Based on an integrative taxonomic approach, a new species of the genus Loxosceles Heineken & Lowe, 1832, is described from the state of Hidalgo, Mexico. Loxosceles tolantongo sp. nov. is described based on DNA barcoding using cytochrome c oxidase subunit 1 (CO1) and internal transcribed spacer 2 (ITS2), and morphology. For species delimitation, four molecular methods were implemented: 1) corrected p-distances under neighbor joining (NJ); 2) automatic barcode gap discovery (ABGD); 3) general mixed yule coalescent model (GMYC) and 4) Bayesian Poisson tree processes (bPTP). The new species morphologically resembles L. jaca, another species from Hidalgo, but there are morphological differences mainly in the tibiae of the male palp, the seminal receptacles of the females and also the high genetic p-distances. CO1 was more informative than ITS2 for the genetic separation; however, both concatenated genes (CO1 + ITS2) present robust evidence for species delimitation. Loxosceles tolantongo sp. nov. is considered a unique species for four reasons: 1) it can be diagnosed and distinguished by morphological characters (of the male palps mainly, but also of the seminal receptacles of the females); 2) the genetic p-distances with CO1 were high (>10%); 3) the molecular species delimitation methods were congruent under CO1 and CO1 + ITS2; and 4) under CO1 and CO1 + ITS2, the new species is a putative sister group of L. jaca + L. tenango.
The tribal allocation of Xalitla Lane, 1959 (Cerambycidae: Cerambycinae) is discussed. Xalitla limoni Santos-Silva and Skillman, new species,is described from Mexico (Jalisco). Xalitla lezamai Galileo and Martins,2008 is determined to be synonymous with X. genuina Martins,1970 and formally placed in synonymy. A key to the species of Xalitla, which includes the new species and synonymy, is provided.
Phlyctinus callosus (Schoenherr, 1826) (Curculionidae, Entiminae, Oosomini) is a species native to the Western Cape province of the Republic of South Africa. It is regarded as a key pest of orchards and vineyards. Detailed observations of its morphology and ecology have shown this species to be a complex of closely related species. In this study we describe the species of this complex, provide morphological and molecular diagnostic tools to distinguish between species, and review their distribution and host plant associations. In all, six species are recognized in the P. callosus complex and five are described as new (P. grootbosensis Haran sp. nov., P. xerophilus Haran sp. nov., P. planithorax Haran sp. nov., P. littoralis Haran sp. nov., P. aloevorus Haran sp. nov.). Sequences of the mitochondrial gene used (cytochrome oxidase I, COI) indicated that P. xerophilus Haran sp. nov. might comprise several cryptic species for which stable morphological features could not be identified at this stage. The species of the genus Phlyctinus appear to be primarily associated with various Asteraceae found in humid, sandy and disturbed habitats.
Description of two new genera and a taxonomic key to the world genera of Cybocephalidae (Coleoptera)
(2020)
The sixteen genera of Cybocephalidae (Coleoptera) occurring worldwide are listed and keyed. The genera included are Amedissia Kirejtshuk and Mantič, Apastillus Kirejtshuk and Mantič, Cybocephalus Erichson, Endrodiellus Endrödy-Younga, Eupastillus Lawrence, Hierronius Endrödy-Younga, Horadion Endrödy-Younga, Pacicephalus Kirejtshuk and Mantič, Pastillocenicus Kirejtshuk and Nel, Pastillodes Endrödy-Younga, Pastillus Endrödy-Younga, Pycnocephalus Sharp, Taxicephomerus Kirejtshuk, Theticephalus Kirejtshuk, a description of a new genus, Microthomas T. R. Smith, with one new species, M. brevicornis T. R. Smith, from Bolivia, and a new genus, Conglobatus T. R. Smith, with two new species, C. armatus T. R. Smith from Central and South America and C. fullertoni T. R. Smith from Dominica. A key to genera, illustrations of morphological features, and distributional data are provided. The genus Nodola Bréthes is found to be a new synonym of Cybocephalus Erichson. The transfer of Nodola chilensis Bréthes into Cybocephalus creates a secondary homonymy with C. chilensis Reitter. Nodola chilensis Bréthes is here given a new name, Cybocephalus brethesi T. R. Smith.
Two new species of Phyxelididae are described from southern Africa: Xevioso cepfi sp. nov. (♂♀), from mountains in the Niassa Province of northern Mozambique, and X. megcummingae sp. nov. (♂♀), from urban Harare, northern Zimbabwe and the Viphya Mts in Malawi. They represent the northernmost localities of the genus. An identification key, partially adapted for the new species, is presented. The biogeographical importance of the mountain areas on both sides of the northern part of Lake Malawi is discussed.
Thirteen species of Echinoderes with nearly identical spine/tube patterns, and apparently similar tergal extensions were re-examined and compared. Based on this, redescriptions and/or emended species diagnoses are provided for Echinoderes aureus, E. dujardinii, E. gerardi, E. imperforatus, E. pacificus, E. pilosus, E. sensibilis, E. sublicarum and E. worthingi, and new details about cuticular structures are added for E. kozloffi and E. gizoensis. The new information derived from the redescriptions, and the subsequent comparative studies revealed that: 1) the holotype of Echinoderes lanceolatus is identical with the types of Echinoderes aureus, and E. lanceolatus is thus a junior synonym of E. aureus; other potentially synonymous species that should be addressed further in the future include: E. dujardinii + E. gerardi; E. imperforatus + E. sensibilis, and E. pacificus + E. sublicarum; 2) the paratypes of E. lanceolatus represented a different yet undescribed species, here described as E. songae Sørensen & Chang sp. nov.; 3) a comparison with literature information about E. ehlersi showed that the species is so insufficiently described that a redescription of topotype material is required before the species should be considered for taxonomic comparison; 4) specimens from the Andaman Islands, India, that previously have been reported as Echinoderes cf. ehlersi represent two different undescribed species, of which one is described as E. chandrasekharai Sørensen & Chatterjee sp. nov. and the other is left undescribed due to the limited material available; 5) out of a total of fifteen addressed species, it is proposed that eleven represent a putatively monophyletic group that is named the Echinoderes dujardinii group. The group includes following species: E. dujardinii, E. ehlersi, E. gerardi, E. imperforatus, E. kozloffi, E. sensibilis, E. pacificus, E. sublicarum, E. songae Sørensen & Chang sp. nov., E. chandrasekharai Sørensen & Chatterjee sp. nov., and Echinoderes sp. from the Andaman Islands, and is supported by a similar spine/tube pattern (except for variation regarding the presence of lateral accessory tubes on segment 8); generally short middorsal spines, especially on segments 4 to 6; glandular cell outlets type 1 always present in middorsal positions on segments 1 to 3, and in subdorsal positions on segments 4 to 9; glandular cell outlets type 2 always present in laterodorsal or midlateral positions on segment 8, and sometimes in same positions on segment 9 but never at any other segments or positions; female papillae always present on sternal plates of segments 7 and 8, and occasionally also on segment 6; tergal extensions well-spaced, triangular, gradually tapered cones, and pectinate fringes of sternal extensions are differentiated into seta-like tufts. The comparisons furthermore showed potential taxonomic significance of two echinoderid character traits that previously have been slightly neglected as diagnostic traits, namely the presence and appearance of female papillae, and the dorsal pattern of glandular cell outlets type 1. Female papillae may occur on the sternal plates of segments 6 to 8, but the positions may differ from ventrolateral to ventromedial, and the morphology of the intracuticular substructure also differ at species level. Information about position and morphology of female papillae proved helpful for species recognition, but it might also provide information of phylogenetic importance. Analyses of glandular cell outlet type 1 patterns on the dorsal sides of segments 1 to 9 in species of Echinoderidae, revealed several apparently unique or rare patterns, but also three distinct patterns that applied to larger groups of species. One pattern is the one present in all species of the E. dujardinii group, whereas the other two common patterns included 1) middorsal outlets on segments 1 to 3, and paradorsal outlets on segments 4 to 9 (found in 27 species), and 2) middorsal outlets on segments 1 to 3, 5 and 7, and paradorsal outlets on segments 4, 6 and 8 to 9 (found in 27 species).
Micropterigidae is a family of Lepidoptera characterized by plesiomorphic morphological characters. Presently, this family consists of more than 22 genera and is distributed throughout all biogeographic realms. Vietomartyria Hashimoto & Mey, 2000 presently consists of six species mainly from South China. Two new species of the genus, V. wuyunjiena sp. nov. and V. maoershana sp. nov., are described herein from China; adult genitalia and wing venation are illustrated. Some biological accounts of the new species are also provided. A key to all described Vietomartyria species is given.
El tipo primario de Psiloptera costata Fairmaire, actualmente en Ectinogonia Spinola (Coleoptera: Buprestidae), fue descubierto y se designa lectotipo. Como la descripción original es incompleta, la especie es brevemente redescrita e ilustrada en función del lectotipo. Adicionalmente, con base en ejemplares de Ectinogonia Spinola recolectados en planicies litorales de lasregiones de Atacama y Coquimbo, se describe una nueva especie del desierto costero de Chile, E. gigantea Pineda y Mondaca, nueva especie.Se presentan caracteres diagnósticos, fotografías de los adultos y de los órganos genitales del macho y la hembra, junto a observaciones sobre el hábitat, historia natural, y distribución del nuevo taxón.
The oomycete genus Ectrogella currently comprises a rather heterogeneous group of obligate endoparasitoids, mostly of diatoms and algae. Despite their widespread occurrence, little is known regarding the phylogenetic affinities of these bizarre organisms. Traditionally, the genus was included within the Saprolegniales, based on zoospore diplanetism and a saprolegnia/achlya-like zoospore discharge. The genus has undergone multiple re-definitions in the past, and has often been used largely indiscriminately for oomycetes forming sausage-like thalli in diatoms. While the phylogenetic affinity of the polyphyletic genus Olpidiopsis has recently been partially resolved, taxonomic placement of the genus Ectrogella remained unresolved, as no sequence data were available for species of this genus. In this study, we report the phylogenetic placement of Ectrogella bacillariacearum infecting the freshwater diatom Nitzschia sigmoidea. The phylogenetic reconstruction shows that Ectrogella bacillariacearum is grouped among the early diverging lineages of the Saprolegniomycetes with high support, and is unrelated to the monophyletic diatom-infecting olpidiopsis-like species. As these species are neither related to Ectrogella, nor to the early diverging lineages of Olpidiopsis s. str. and Miracula, they are placed in a new genus, Diatomophthora, in the present study.
Dichromatobolus, a new genus of spirobolidan millipedes from Madagascar (Spirobolida, Pachybolidae)
(2020)
A new genus, Dichromatobolus gen. nov., belonging to the genus-rich mainly southern hemisphere family Pachybolidae of the order Spirobolida, is described based on D. elephantulus gen. et sp. nov., illustrated with color pictures, line drawings, and scanning electron micrographs. The species is recorded from the spiny bush of southwestern Madagascar. Dichromatobolus elephantulus gen. et sp. nov. shows an unusual color pattern, sexual dichromatism with males being red with black legs and females being grey. Males seem to be more surface active, as mainly males were collected with pitfall traps. Females mainly come from the pet trade. The body of this species is short and very wide, being only 8 times longer than wide in the males. Live observations show the species is a very slow mover, digging in loose soil almost as fast as walking on the surface. The posterior gonopods of Dichromatobolus gen. nov. are unusually simple and well-rounded, displaying some similarities to the genera Corallobolus Wesener, 2009 and Granitobolus Wesener, 2009, from which the new genus differs in numerous other characters, e.g., size, anterior gonopods and habitus. Despite several attempts with fresh tissue samples and different primers, molecular barcoding did not work for Dichromatobolus gen. nov. Any relationships to the other 15 genera of Pachybolidae indigenous to Madagascar remain unknown.
Die Publikationsgeschichte der vielbändigen "Illustrierten Flora von Mitteleuropa", begründet durch Gustav Hegi (1876-1932), wird bis zur Beendigung der Print-Ausgabe nachgezeichnet. Der Band III/3, betreffend die Paeoniaceae, Ceratophyllaceae, Nymphaeaceae und Ranunculaceae, war im Jahr 1974 in der zweiten Auflage herausgegeben worden. Die Arbeiten an einer dritten Auflage waren noch nicht zu einem Abschluss gekommen, als der Verlag entschied, die Publikation von Hegi-Neubearbeitungen ganz einzustellen. Um bereits vorliegende Bearbeitungen zur Familie Ranunculaceae zugänglich zu machen, werden diese als Online-Publikationen in Kooperation mit der "Gesellschaft zur Erforschung der Flora Deutschlands" (GEFD) realisiert.
Most fossil feather stars are known only from the centrodorsal often connected to the radial circlet. This is the case for Discometra rhodanica (Fontannes, 1877), the type species of the genus Discometra, collected from the Late Burdigalian of the Miocene Rhône-Provence basin (southeastern France). The quarries operating in this area have exposed layers from the Late Burdigalian on the northern fl ank of the Lubéron anticline near Ménerbes (basin of Apt, Vaucluse, southeastern France). These layers contain exceptionally well-preserved echinoderms, among which are three specimens of a feather star with cirri and arms still connected to the centrodorsal. They are attributed to a new species: Discometraluberonensis sp. nov. (Himerometridae). The number of arms can reach 60, as in extant species of the genus Himerometra, but the pattern of arm divisions is closer to that of the genus Heterometra, which has no more than 45 arms in extant species. Discometra luberonensis sp. nov. diff ers from D. rhodanica by the characters of its centrodorsal. Here we redescribe the centrodorsal and radial circlets of D. rhodanica based on previously and newly collected specimens. We designate a neotype for D. rhodanica, because the holotype is considered lost. Affi nities between Discometra, Himerometraand Heterometra are discussed.
Acacia meiantha Tindale & Herscovitch, (Fabaceae) a low to medium shrub with root suckering, is only known to occur at three locations, Clarence, Carcalgong and Mullion Creek in Central West New South Wales. These disjunct populations each separated by >60 km, are considered as isolated subpopulations. A compilation of recent field surveys shows that of the 42,000 stem clusters/aggregates of Acacia meiantha estimated across the three geographic locations, the majority, 39,900 (96%) occur in the Mullions Range State Forest subpopulation, where 61% of clusters occur in the remnant native forest areas and 39% in the plantation forestry compartments. At Carcalgong 1,566 stem clusters were recorded along narrow roadside reserves. The Clarence subpopulation consists of < 400 stem clusters precariously situated among a confluence of road, railway and electricity power-line easements. Ecological observations of habitat are presented; information relating to genetic diversity, seed biology, reproductive biology and response to fire is found to be Data Deficient. The threatened species listing as Endangered under both State and Commonwealth legislation is warranted; the species does not occur on any conservation lands, has restricted distribution and abundance, and is vulnerable to ongoing threats. The area (AOO) and extent of occupancy (EOO) are calculated. It occurs at three locations (< 5), has an estimated EOO of 2,900 km2 (< 5,000 km2) and an AOO of 80 km2 (< 500 km2) (IUCN (2019) thresholds in brackets); there are significant threats to the extent and quality of habitats. Additional opportunities for improving the conservation of the species, particularly in the Mullions Range State Forest, over and above those outlined in the site-managed initiatives of the current Saving our Species program, are presented.
This paper provides a taxonomic assessment and distribution details of the species of the genus Ludwigia L. (Onagraceae) for the Paraíba State, Northeastern Brazil. Six species were found: L. erecta (L.) H.Hara, L. helminthorrhiza (Mart.) H.Hara, L. hyssopifolia (G.Don) Exell, L. leptocarpa (Nutt.) H.Hara, L. nervosa (Poir.) H.Hara and L. octovalvis (Jacq.) P.H.Raven. Ludwigia nervosa was recorded for the first time in the studied area. Our taxonomic treatment comprises an identification key to the species. For each species, description, illustrations, taxonomic comments, flowering and fruiting data, geographic distribution map, and the conservation status for the studied area are provided. Among the recorded species, three were classified as "Near Threatened", two as "Vulnerable" and one as "Critically Endangered".
Actualmente existen dos especies de gorgojos (Coleoptera: Curculionidae) que barrenan los frutos de la palma de chontaduro Bactris gasipaes Kunth en Colombia y que ocasionan pérdidas de hasta el 100% de la producción. Palmelampius heinrichi O’Brien es la principal plaga del cultivo en toda la costa pacífica y en vastas regiones de la amazonia y el piedemonte llanero. En este trabajo se describe una nueva especie del género Parisoschoenus Faust, P. bactrisae Constantino y Pardo-Locarno que ocurre simpátricamente con P. heinrichi en la costa pacífica de Colombia causando un daño similar y que se diferencia de la especie anterior por la presencia de cuernos prosternales notorios en los machos. Adicionalmente, se describe una nueva especie de Cylindrocerus Schönherr, C. loxodontus Constantino y Pardo-Locarno, que presenta cuernos prosternales recurvados, asociada a las inflorescencias de la palma de chontaduro y se alimenta del polen de las brácteas.
Dyslexia Skelley and Gasca-Álvarez, new genus (Coleoptera: Erotylidae: Erotylinae: Erotylini), is described and illustrated. The genus is comprised of four new species, all described by Skelley and Gasca-Álvarez: D. belamyi, D. dathomirria, D. pulcricolor, and D. tomasi. The unique broad head structures of this genus are characterized and compared with other genera. Problems associated with the taxonomy of Erotylini are discussed.
Déterminants de l’utilisation de Acacia auriculiformis comme bois d’œuvre en Afrique de l’Ouest
(2020)
Acacia auriculiformis, un bois énergie, suscite de plus en plus des intérêts de bois d’œuvre au niveau des industriels de bois au Bénin. L’appréciation des performances de l’espèce dans les usines et en plantation est déterminante pour la vul- garisation de l’espèce comme alternative pour mitiger la déforestation en lien avec la demande en bois d’œuvre. L’objectif principal de ce travail est donc d’évaluer les conditions entourant l’adoption de Acacia auriculiformis comme espèce de bois d’œuvre au Bénin, Afrique de l’Ouest. Au total, 154 usines de bois et 25 plantations ont été enquêtées dans les zones abritant les plantations à A. auriculiformis. A. auriculiformis est l’espèce la plus fréquente dans les usines de bois (81%) suivie de Afzelia africana (55%), Tectona grandis (47%) et Khaya senegalensis (47%). Les superficies des plantations à A. auriculi- formis ont augmenté entre 1999 et 2019. Les connaissances sur l’utilisation de ce bois sont variables dans la zone d’étude. Le bois de A. auriculiformis est apprécié comme bois d’œuvre parce qu’il présente une couleur esthétique, un séchage rapide, une facilité de mise en œuvre, une imprégnabilité élevée, une densité moyenne à élevée et un bel aspect après mise en œuvre. Cependant, son bois fournit beaucoup de sciure, a beaucoup de nœuds et présente une déformabilité moyenne. Sa disponibili- té et son accessibilité sont les principaux facteurs justifiant la préférence de l’espèce par les industriels de bois d’œuvre. Cette forme d’utilisation de l’espèce est également remarquée au Togo, en Côte d’Ivoire. L’espèce présente une bonne perspective d’utilisation comme bois d’œuvre.
Eight new species of Ecuadorian Ptiliidae are described and figured: Nossidium harrietae sp. nov., Ptenidium robustum sp. nov., P. tauriforme sp. nov., P. triangulum sp. nov., Notoptenidium brunneum sp. nov., Americoptilium nigrescens sp. nov., Discheramocephalus nigerrimus sp. nov. and D. striatus sp. nov. The insects were collected by J. McClarin, 2017–2018, in the Napo Province to the southeast of the capital Quito.
In this study, we examine 500 specimens of Anaplecta collected from China, of which 26 samples were used for COI sequencing. We confirm eight new species, i.e., Anaplecta corneola Deng & Che sp. nov., Anaplecta staminiformis Deng & Che sp. nov., Anaplecta arcuata Deng & Che sp. nov., Anaplecta strigata Deng & Che sp. nov., Anaplecta furcata Deng & Che sp. nov., Anaplecta cruciata Deng & Che sp. nov., Anaplecta nigra Deng & Che sp. nov. and Anaplecta bicolor Deng & Che sp. nov. based on morphological and molecular data using ABGD and GMYC analyses. The results of ABGD and GMYC were basically consistent with the morphospecies of Anaplecta. The intraspecific and interspecific genetic distances of Anaplecta ranged from 0 to 6.6% and 16.8% to 31.8%, respectively. We found the male genitalia of Anaplecta to exhibit intraspecific variation, especially in the phallomeres.
Es wird über einen Fund von Alyxoria ochrocheila an Fraxinus excelsior in Nordrhein-Westfalen bei Hirschrott im Naturschutzgebiet "Erkensruhrtal mit Nebenbächen und Felsen am Oberseeufer" im Nationalpark Eifel berichtet, der einen Neufund für die Nordeifel und den Nationalpark Eifel darstellt. Die Neuansiedlung steht wahrscheinlich im Zusammenhang mit den steigenden Temperaturen im Rahmen des Klimawandels.

Microporella Hincks, 1877 is one of the most diverse genera of cheilostome bryozoans, containing more than 150 named species. Distributed globally since the early Miocene, the majority of species of Microporella have sheet-like colonies encrusting hard and / or ephemeral substrates, while a limited number of species have erect bifoliate colonies starting from an encrusting base. Herein, the four nominal species of erect bifoliate Microporella (M. bifoliata, M. hastigera, M. hyadesi and M. ordo) are revised, and one new Pliocene (M. tanyae sp. nov.) and three new Recent species (M. ordoides sp. nov., M. lingulata sp. nov. and M. modesta sp. nov.) are formally described. Furthermore, the lectotype and paralectotypes were designated for M. bifoliata and M. hastigera. An additional Recent species, Microporella sp. 1, is also described and illustrated but left in open nomenclature owing to the absence of ovicells in the single available fragment. Although the molecular phylogeny of Microporella has yet to be resolved, the diversity of character states present among the erect bifoliate species described here suggests that this colony growth-form is not monophyletic but has evolved on multiple occasions.
After publication of Armitage and Harris (2020), it was noticed that the wrong illustrations were used for the species Neotrichia espinosa Armitage and Harris (Fig. 9) and Neotrichia michaeli Armit-age and Harris (Fig. 10), resulting in images that did not correspond to the captions. The authors and the Insecta Mundi editorial staff apologize for this error. The intended versions of Figures 9 and 10 are reproduced here. Insecta Mundi has also released a revised version of the Armitage and Harris (2020) manuscript, with this error corrected. However, the revised version is not an official peer-reviewed article, and anyone wishing to reference the findings of Armitage and Harris (2020) should cite the original manuscript or this erratum.
Ein kleiner Bestand von Ranunculus parviflorus konnte im Mai 2019 erstmals für Nordrhein-Westfalen in einem lückigen Scherrasen auf dem Friedhof in Zülpich-Juntersdorf/Kreis Euskirchen nachgewiesen werden. Das Vorkommen in Juntersdorf sowie die Merkmale, Verbreitung und Ökologie der mediterran-atlantischen Art werden diskutiert.
Campodeinae is the most diverse subfamily of Campodeidae diplurans and inhabits soils and subsurface ecosystems. These are distributed in the Palearctic area, clearly rarifying towards northern latitudes. The major taxonomic characters are chaetotaxy, shape and complexity of pretarsal structures, and secondary sexual characters. This monograph provides a taxonomic revision of the subfamily Campodeinae in the Euro-Mediterrnean region, based on extensive literature review and new material studied. It comprises detailed morphological descriptions and illustrations together with habitat and distribution data of 161 species and 14 subspecies from 10 genera: Campodea Westwood, 1842, Edriocampa Silvestri, 1933, Eutrichocampa Silvestri, 1902, Helladocampa Condé, 1984, Libanocampa Condé, 1955, Litocampa Silvestri, 1933, Oreocampa Condé, 1950, Podocampa Silvestri, 1932, Remycampa Condé 1952, and Spaniocampa Silvestri, 1933. With 116 species Campodea is the most diverse and widely distributed genus in the studied area.
The subfamily Sepiolinae (Mollusca: Cephalopoda: Sepiolidae), currently containing the genera Sepiola Leach, 1817, Euprymna Steenstrup, 1887, Inioteuthis Verrill, 1881, Rondeletiola Naef, 1921 and Sepietta Naef, 1912, is characterized by the hectocotylization of the left dorsal arm, i.e., its transformation into a copulatory organ thanks to modifications of sucker/pedicel elements. The hectocotylus morphology varies to a great extent across genera and species. In particular, one to several pedicels in its proximal third lose their sucker and become highly and diversely modified in shape to constitute a copulatory apparatus. An evolutionary gradient was observed in the copulatory apparatus morphology, from the simple modification into a papilla of just one pedicel from the third element of the ventral sucker row (some nominal species of Euprymna) to a quite complex structure involving several variously modified pedicels from both the ventral and dorsal sucker rows (Inioteuthis). In some species, elements in the distal portion of the hectocotylus may also be highly modified, such as the columnar suckers in Euprymna. The hectocotylian diversity allows to distinguish nine groups of species that do not match the current generic subdivision of Sepiolinae. Additional morphological characters (number of sucker rows on arms, female bursa copulatrix, occurrence and shape of visceral light organs, etc.) corroborate the subdivision of Sepiolinae into nine subtaxa, i.e., genera. Accordingly, a cladogram is drawn to describe the possible phylogenetic relationships among the nine clades. To comply with these results, all current genera are redefined and four new genera are described, namely Adinaefiola gen. nov., Boletzkyola gen. nov., Eumandya gen. nov. and Lusepiola gen. nov.
We report on fourteen species and four genera of Tischeriidae recorded from Las Cuevas, a single tropical forest locality in Belize, Central America. This is the highest number of species of Tischeriidae recorded from a single locality worldwide, exceeding the species and generic diversity of the entire Tischeriidae fauna of Europe and accounting for about 9% of the documented global fauna for this family. We describe and name six new species: Astrotischeria papilloma Diškus & Stonis sp. nov., mining on Lasianthaea fruticosa (L.) K.M.Becker (Asteraceae); A. scutifera Diškus & Stonis sp. nov., mining on Sida glabra Mill. (Malvaceae); A. basilobata Remeikis & Stonis sp. nov., mining on Lasianthaea fruticosa; Paratischeria robinsoni Diškus & Stonis sp. nov., mining on Otopappus verbesinoides Benth. (Asteraceae); P. tubifex Diškus & Stonis sp. nov., mining on Lasianthaea fruticosa; and P. belizensis Remeikis & Stonis sp. nov. (host plant unknown). Additionally, we review eight previously described species from the same period of collecting at Las Cuevas in 1997–1998: A. selvica Diškus, Carvalho-Filho & Stonis, 2018, mining on Sphagneticola trilobata (L.) Pruski and Synedrella nodiflora (L.) Gaertn. (Asteraceae); A. casila Diškus & Stonis, 2018, mining on Montanoa atriplicifolia (Pers.) Sch.Bip. (Asteraceae); A. furcata Diškus & Stonis, 2018 (host plant unknown); Paratischeria neotropicana (Diškus & Stonis, 2015), mining on Sida L. (Malvaceae), including S. rhombifolia L.; Dishkeya gouaniae (Stonis & Diškus, 2007), mining on Gouania polygama (Jacq.) Urb. (Rhamnaceae); Coptotriche pulverea (Walsingham, 1897), mining on Terminalia amazonia (J.F.Gmel.) Exell (Combretaceae); C. forsteroniae Stonis & Diškus, 2008, mining on Forsteronia myriantha Donn Sm. (Apocynaceae); and C. singularis Stonis & Diškus, 2008 (host plant unknown). All taxa, except for C. singularis, are illustrated with photographs of the adults and their genitalia. We also briefly discuss the discovery of some novel characters for Astrotischeria Puplesis & Diškus, 2003 and Paratischeria Diškus & Stonis, 2017, Tischeriidae, and provide the first photographic documentation of Coptotriche pulverea and C. forsteroniae.
Our knowledge of early evolution of snakes is improving, but all that we can infer about the evolution of modern clades of snakes such as boas (Booidea) is still based on isolated bones. Here, we resolve the phylogenetic relationships of Eoconstrictor fischeri comb. nov. and other booids from the early-middle Eocene of Messel (Germany), the best-known fossil snake assemblage yet discovered. Our combined analyses demonstrate an affinity of Eoconstrictor with Neotropical boas, thus entailing a South America-to-Europe dispersal event. Other booid species from Messel are related to different New World clades, reinforcing the cosmopolitan nature of the Messel booid fauna. Our analyses indicate that Eoconstrictor was a terrestrial, medium- to large-bodied snake that bore labial pit organs in the upper jaw, the earliest evidence that the visual system in snakes incorporated the infrared spectrum. Evaluation of the known palaeobiology of Eoconstrictor provides no evidence that pit organs played a role in the predator–prey relations of this stem boid. At the same time, the morphological diversity of Messel booids reflects the occupation of several terrestrial macrohabitats, and even in the earliest booid community the relation between pit organs and body size is similar to that seen in booids today.
The Chinese fauna of the pselaphine genus Sathytes Westwood (Batrisitae: Batrisini) currently includes 20 species. In this paper, 15 new species from various provinces of the country are described: S. alpicola sp. nov. (Xizang), S. australis sp. nov. (Guangdong, Guangxi), S. chayuensis sp. nov. (Xizang), S. chengzhifeii sp. nov. (Yunnan), S. huapingensis sp. nov. (Guangxi), S. linzhiensis sp. nov. (Xizang), S. maoershanus sp. nov. (Guangxi), S. nujiangensis sp. nov. (Yunnan), S. panzhaohuii sp. nov. (Xizang), S. shennong sp. nov. (Hubei), S. tianquanus sp. nov. (Sichuan), S. transversus sp. nov. (Xizang), S. valentulus sp. nov. (Guangxi), S. xingdoumontis sp. nov. (Hubei) and S. xizangensis sp. nov. (Xizang). New collection records are provided for S. longitrabis Yin & Li, 2012, S. tangliangi Yin & Li, 2012 and S. yunnanicus Yin & Li, 2012. Maps showing the distribution of the genus in China, and an updated checklist of the world species are provided.
Salacia crassifolia (Mart. ex Schult.) G.Don., (Celastraceae) is a native species of shrub/tree highly appreciated in Brazil for its fruits and medicinal properties. Scale insects have never been reported associated with S. crassifolia; nevertheless, this paper describes the occurrence of two diaspidids on S. crassifolia leaves in Brazil. Three mature trees were inspected in February and March 2018 and scale insect samples were collected and preserved in 70% alcohol, then mounted and identified under an optical microscope. Two species of scale insects were found associated with this plant, Pseudoparlatoria argentata Hempel and Melanaspis aristotelesi Lepage and Giannotti, both from the family Diaspididae (Hemiptera). The three observed trees were infested by the diaspidids, with some leaves completely colonized by both species. This is the first reported occurrence of P. argentata and M. aristotelesi in plants of the Celastraceae family. It is also the first report of these insects in the Distrito Federal, Brazil, expanding the distribution and hosts in native plant species of the Cerrado biome.
Chromosome counts of Lactuca viminea from Cyprus revealed the diploid number 2n = 18, which confirms results from other parts of its distribution range. Cultivation of plants corroborated the existence of two habit forms but assignment of Cypriot material to infraspecific taxa still seems to be premature.
Prey Long (Prey Lang) Forest is the largest remaining lowland rainforest in Indochina, shared by Stung Treng, Preah Vihear, Kampong Thom and Kratie Provinces of Cambodia, which has been persisted until present because of the lack of roads. It includes patches of unique evergreen swamp forests. Odonata of Prey Long forest, including Cheum Takong forest swamp, was briefly examined in December 2019, while the already deforested area was examined in June 2018. The former examination resulted in 40 species, the latter in 34 species, 60 species in total. Two species, Copera chantaburii Asahina, 1984 and Burmagomphus williamsoni Förster, 1914, are for the first time reported for Cambodia from the deforested area (Chey Saen District of Preah Vihear Province). The swamped forest of Cheum Takong provided 17 species, 5 of which were not found elsewhere in the considered area, 3 are rare and 4 generally Sondaic. Prey Long Forest should be re-examined in the rainy season soon after the road to Spong village is constructed.
The Isla Sala y Gómez or Motu Motiro Hiva is located 415 km northeast of Rapa Nui (Easter Island) and 3420 km from the coast of northern Chile. It is a small oceanic island (2.5 km2) dominated by volcanic rock with very little vegetal cover. Here, we describe the first endemic arachnid for the island, Ariadna motumotirohiva sp. nov. Females are similar to those of Ariadna perkinsi Simon, 1900 from Hawaiʻi and Ariadna lebronneci Berland, 1933 from the Marquesas in the dorsal dark abdominal pattern, but they differentiate from the latter in the anterior receptaculum, promarginal cheliceral teeth and leg IV macrosetae. A recent survey of the arachnid fauna of Rapa Nui, which included Motu Nui and the rocky shores, did not record the presence of the family Segestriidae, neither has it been found during previous surveys. However, it is not possible to discard the possibility of a local extinction on Rapa Nui and survival on Sala y Gómez. This study suggests other endemic terrestrial arthropods could be present on this very small and remote island.
The present corrigendum corrects errors that occurred in: Petzold A., Magnant A.-S., Edderai D., Chardonnet B., Rigoulet J., Saint-Jalme M. & Hassanin A. 2020. First insights into past biodiversity of giraffes based on mitochondrial sequences from museum specimens. European Journal of Taxonomy 703: 1–33. https://doi.org/10.5852/ejt.2020.703
Intensified exploration of sub-Saharan Africa during the 18th and 19th centuries led to many newly described giraffe subspecies. Several populations described at that time are now extinct, which is problematic for a full understanding of giraffe taxonomy. In this study, we provide mitochondrial sequences for 41 giraffes, including 19 museum specimens of high importance to resolve giraffe taxonomy, such as Zarafa from Sennar and two giraffes from Abyssinia (subspecies camelopardalis), three of the first southern individuals collected by Levaillant and Delalande (subspecies capensis), topotypes of the former subspecies congoensis and cottoni, and giraffes from an extinct population in Senegal. Our phylogeographic analysis shows that no representative of the nominate subspecies camelopardalis was included in previous molecular studies, as Zarafa and two other specimens assigned to this taxon are characterized by a divergent haplogroup, that the former subspecies congoensis and cottoni should be treated as synonyms of antiquorum, and that the subspecies angolensis and capensis should be synonymized with giraffa, whereas the subspecies wardi should be rehabilitated. In addition, we found evidence for the existence of a previously unknown subspecies from Senegal (newly described in this study), which is now extinct. Based on these results, we propose a new classification of giraffes recognizing three species and 10 subspecies. According to our molecular dating estimates, the divergence among these taxa has been promoted by Pleistocene climatic changes resulting in either savannah expansion or the development of hydrographical networks (Zambezi, Nile, Lake Chad, Lake Victoria).
Cypherotylus dromedarius (Lacordaire, 1842) (Coleoptera: Erotylidae) was described from French Guiana. Information about its current distribution is scattered throughout the literature and the internet. Specimens of this species were recently observed and photographed in the Boquete area, Chiriqui Province, Panama, and constitute a new record for the country of this species. Subsequently, we located two specimens deposited in the National Reference Collection of the G. B. Fairchild Museum of Invertebrates, University of Panama, from the same locality in Chiriqui Province. We summarize the distribution of this species from scattered sources and provide five new records.
In April 2017, several scale insect specimens in the family Dactylopiidae were collected from infested cladodes of wild Opuntia tomentosa Salm-Dyck, 1822 (Cactaceae) in the outskirts of Morelia City, Michoacan, Mexico. The specimens were identified as Dactylopius confusus (Cockerell, 1929) (Hemiptera: Coccomorpha: Dactylopiidae). In this article, the presence of D. confusus in Michoacan state, Mexico, is recorded for the first time. A subsequent finding of D. confusus on Opuntia ficus-indica (L.) Mill., (1768) (Cactaceae) in October 2019 was confirmed with 18S rDNA and 28S rDNA.
In April 2018, specimens of an asterolecaniid were collected on infested wild plants of Asclepias curassavica Linnaeus, 1753 (Gentianales: Asclepiadaceae) in Jiquilpan, Michoacan, Mexico. The collected specimens were identified as Planchonia stentae (Brain,1920) (Hemiptera: Asterolecaniidae). In this paper, we record for the first time the presence of P. stentae infesting A. curassavica in Mexico.
First record of the orchid bee Euglossa dilemma (Hymenoptera: Apidae) in Hispaniola, the Antilles
(2020)
The occurrence of the orchid bee Euglossa dilemma Bembé and Eltz (Hymenoptera: Apidae) is recorded for the first time for the island of Hispaniola in the Greater Antilles. Males were observed visiting varieties of sweet basil plants (Ocimum basilicum Linnaeus (Lamiaceae)) to obtain fragrances used during courtship and reproduction. Our observations showed that the species is established in Hispaniola and that it does not require the presence of orchids for reproductive success, being able to adapt to new plant resources it finds in the areas it colonizes. These observations correspond to what was found in Florida, United States, where Euglossa dilemma was also recently introduced. It is not clear how the species was introduced to Hispaniola, but Euglossa dilemma is clearly an adventive species that is colonizing the Antilles in addition to peninsular Florida.
The family Hahniidae is reported from Thailand for the first time. The genus Hexamatia gen. nov. and two new species, Hexamatia seekhaow gen. et sp. nov. and Hahnia ngai sp. nov., are described and illustrated. DNA sequences are provided for all the species reported here. The phylogenetic position of the novel genus Hexamatia gen. nov. and its relation to Hahnia are discussed. Based on these results, a new combination is proposed for Hexamatia senaria (Zhang, Li & Zheng, 2011) gen. et comb. nov. = Hahnia senaria. Known distribution of the species Hahnia saccata Zhang, Li & Zheng, 2011, originally described from China, is expanded. A brief review and notes on the taxonomy of the six-eyed hahniids are included.
Ancognatha aymara Mondaca, 2016 (Coleoptera: Scarabaeidae: Dynastinae: Cyclocephalini), a species previously known only from Chile, is recorded for the first time in northern Argentina. The new records are based on male specimens collected in the provinces of Jujuy and Salta. Illustrations of the habitus and male genitalia of the species are presented in color photographs. A map with its current distribution in Chile and Argentina is included.
Brachyplatys subaeneus (Westwood) (Hemiptera: Plataspidae), is reported from Miami Beach, FL, the first report from the United States. It was noticed first on a photo-sharing site (iNaturalist) providing an example of the importance of these sites for helping to track introduced species. Information on distribution, host plants and potential spread are provided along with photos and taxonomic characters to assist with identification of this recently introduced species.
A new phylogenetic hypothesis is proposed for the relationships among the species within the genus Docosia Winnertz, 1863, based on a combined analysis of five DNA markers (28S, ITS2, COI, COII and CytB). Five new species are described, Docosia anatolica Ševčík sp. nov. from Turkey, D. japonica Kurina sp. nov. from Japan, D. peloponnensis Ševčík sp. nov. from Greece, D. svanetica Kurina sp. nov. from Caucasus and D. polyspina Kurina sp. nov. from the Russian Far East. New country records of the following species are presented: D. diutina Plassmann, 1996 (Turkey), D. flavicoxa Strobl, 1900 (Georgia), D. gilvipes (Haliday in Walker, 1856) (Georgia), D. kerkini Kurina & Ševčík, 2011 (Bulgaria), D. moravica Landrock, 1916 (Georgia), D. pannonica Lastovka & Ševčík 2006 (Georgia) and D. rameli Kurina & Ševčík, 2011 (Slovakia).
Five new species of Peltonotellini (Caliscelinae) are described and illustrated: Bruchomorpha pseudodorsata sp. nov., Fitchiella brachyrhina sp. nov., Protrocha nigrilutea sp. nov. and P. punctatosa sp. nov. from Mexico, and Fitchiella zahniseri sp. nov. from Panama. Additionally, five previously described species are redescribed based on newly collected specimens: Aphelonema brevata Caldwell, 1945 (proposed original combination), Bruchomorpha decorata Metcalf, 1923, Bruchomorpha mormo Kirkaldy, 1907, Nenema virgata (Doering, 1941) and Protrocha nesolitaria (Caldwell, 1945). Bruchomorpha decorata is recorded from Panama for the first time. Redescriptions provide new information on the distribution of sensory pits and the first detailed descriptions of male and female terminalia for these species.
Five new species of Meta Koch, 1836 (Araneae: Tetragnathidae) from Gaoligong Mountains, China
(2020)
Five new species of the genus Meta C.L. Koch, 1836 from the Gongligong Mountains, Yunnan are described: Meta hamata sp. nov. (♂♀), M. longlingensis sp. nov. (♂), M. tangi sp. nov. (♂♀), M. yani sp. nov. (♂♀) and M. yinae sp. nov. (♂♀). Detailed descriptions of somatic features and genitalic characters, photos of the body and genital organs, line drawings of the copulatory organs and distribution maps are provided.
This paper treats the planthopper genus, Atracis Stål, 1866 (Flatidae: Flatoidinae) in China. Five new species, A. ocularia sp. nov., A. patefacta sp. nov., A. punctulata sp. nov., A. sphaerica sp. nov. and A. ungulata sp. nov., are described and a checklist of all its known species from China is provided.

Diplura is a group of entognathous hexapods, often considered a sister group to insects. They play an important role in recycling organic matter in soil and subterranean terrestrial ecosystems. The Campodeidae is the most diverse family, divided into four subfamilies. The subfamily Plusiocampinae has a subterranean life-style with many species distributed in the Euro-Mediterranean area. The incertae sedis tachycampoids ("lignée Tachycampoïde") is a group within the family Campodeidae that share with the Plusiocampinae a strong preference for subterranean habitats and several morphological characters, such as slender body shape, elongated appendages, considerable increment in the number of antennomeres and cercal articles, and complexity of sensorial structures. The present monograph provides a taxonomic revision of the subfamily Plusiocampinae and the genera belonging to the tachycampoid lineage from Europe and the Mediterranean region. It comprises detailed morphological descriptions and illustrations together with data on the habitats and distributions of 87 species, 10 subspecies and 11 affinis forms. Seven new species are described among those, namely: Plusiocampa (Plusiocampa) apollo Sendra, Giachino & Vailati sp. nov., P. (P.) chiosensis Sendra & Gasparo sp. nov., P. (P.) dublanskii Sendra & Turbanov sp. nov., P. (P.) hoffmanni Sendra & Paragamian sp. nov., P. (P.) rhea Sendra sp. nov., P. (P.) ternovensis Sendra & Borko sp. nov. and P. (Venetocampa) ferrani Sendra & Delić sp. nov.
Four new Astrothelium species and a Mazaediothecium from Várzea areas in Mato Grosso do Sul, Brazil
(2020)
Five species of lichens are described as new from Várzea areas in Mato Grosso do Sul (Brazil): Astrothelium fernandae, A. pseudodermatodes, A. septoconicum, A. xanthopseudocyphellatum, and Mazaediothecium serendipiticum, the latter being deviating from all other species in its order by the at least morphologically chlorococcoid photobiont. Further, we found 226 identifiable species in the Várzea reserve near Jateí and 47 on a farm near Naviraí. Of these, 15 are new records for Brazil and a further 88 are first reports from the state.
The area comprising the Pyrenees, Northeast Spain, Southern France and Corsica-Sardinia supports a large part of the diversity of Lumbricidae earthworms, including most species of the endemic genera Prosellodrilus, Cataladrilus and Scherotheca. In this region, the probability of encountering new species for science is significant, especially in scarcely sampled localities. In this study, we describe two unidentified species recently collected in the Hyères Archipelago (France), which we assigned to the genera Cataladrilus and Scherotheca based on morphological characters and molecular phylogenetic analyses. Other species of Scherotheca from Montpellier (including the type species of the genus, Sc. gigas gigas) were included in the analysis to clarify their conflicting systematics. A reduced molecular marker set (COI, 16S, 28S and ND1) proved as successful as larger marker sets for identifying phylogenetic relationships within the Lumbricidae. Remarkable disjunctions between both Cataladrilus porquerollensis Marchán & Decäens sp. nov., Scherotheca portcrosana Marchán & Decäens sp. nov. and their most closely related relatives, suggesting a strong influence of paleogeographic events on the earthworm fauna of the area and a possible role of near-shore islands as refugia for relict taxa. Genetic distances and branch lengths supported the elevation of some subspecies of Scherotheca to specific status as well as the retention of other subspecies, highlighting the importance of testing for such delimitation with molecular methods.

The geographical range of the typically host-specific species of chewing lice (Phthiraptera) is often assumed to be similar to that of their hosts. We tested this assumption by reviewing the published records of twelve species of chewing lice parasitizing wild and domestic chicken, one of few bird species that occurs globally. We found that of the twelve species reviewed, eight appear to occur throughout the range of the host. This includes all the species considered to be native to wild chicken, except Oxylipeurus dentatus (Sugimoto, 1934). This species has only been reported from the native range of wild chicken in Southeast Asia and from parts of Central America and the Caribbean, where the host is introduced. Potentially, this discontinuous distribution is due to a low tolerance for dry environments, possibly exacerbated by competitive exclusion by Cuclotogaster heterographus (Nitzsch, 1866). Our examinations of O. dentatus also revealed that this species differs significantly from other species of Oxylipeurus in the male and female genitalia, head structure and chaetotaxy, and other morphological characters. We therefore here erect the monotypic genus Gallancyra gen. nov. for O. dentatus, and redescribe the type species.
The generic status of Winitia Chaowasku (Annonaceae Juss., Miliuseae Hook.f. & Thomson) is reaffirmed by an extensive phylogenetic reconstruction using seven plastome regions (matK, ndhF, rbcL, ycf1 exons; trnL intron; psbA-trnH, trnL-trnF intergenic spacers) and including, among others, seven accessions of Winitia plus two accessions of its sister group, Stelechocarpus Hook.f. & Thomson. The results disclosed a maximally supported clade of Winitia, as well as of Stelechocarpus. The sister relationship of the two genera is still rather poorly supported and the branch uniting them is very short, whereas the branches leading to Winitia and to Stelechocarpus are relatively long, corresponding to their considerable morphological differences. Additionally, in Miliuseae there is a particular indel of eight continuous base pairs in the trnL-trnF intergenic spacer potentially diagnostic for generic discrimination, i.e., members in the same genus possess the same indel structure (absence or presence of a gap), and this indel differentiates Winitia from Stelechocarpus. Winitia cauliflora (Scheff.) Chaowasku appears polyphyletic and Winitia longipes (Craib) Chaowasku & Aongyong comb. nov. based on Stelechocarpus longipes Craib is consequently proposed. Furthermore, our phylogenetic data support a new species, Winitia thailandana Chaowasku & Aongyong sp. nov. from southern Thailand, which is described and illustrated. A key to genera in the sageraeoid clade (Sageraea-Winitia-Stelechocarpus) and a key to the four species of Winitia are provided.
Geography and host spider family are strongly linked in the spider wasps (Hymenoptera: Pompilidae) Entypus unifasciatus (Say) and Tachypompilus ferrugineus (Say) (rusty spider wasp) when 2031 host spider locality records from the years 1918–2020 are mapped. Entypus unifasciatus lycosid host records are plentiful from 43–44° N in the U.S. to northern Mexico. Tachypompilus ferrugineus lycosid host records are numerous from southern Ontario and New England to Mexico east of the Rocky Mountains. Most E. unifasciatus and T. ferrugineus pisaurid host records are from the SE U.S. Trechaleid host records for E. unifasciatus and T. ferrugineus are predominant in southern Mexico and Central America, while ctenid host records for these species are prevalent in northern South America. All E. unifasciatus sparassid host records are from extreme SW U.S. and Mexico, whereas T. ferrugineus sparassid host records are scattered from Texas, Florida and Puerto Rico to Panama. Lycosidae are the predominant host spider family in the Americas for E. unifasciatus (80.3%) and T. ferrugineus (67.4%) followed by Pisauridae (5.4%, 21.7%), Trechaleidae (4.8%, 6.8%), Ctenidae (4.6%, 1.8%), and Sparassidae (4.3%, 1.5%). Lycosidae and Pisauridae are overrepresented in this study as the vast majority of host records (87.8%) are from the U.S. and Ontario, Canada where such species are abundant. Trechaleidae and Ctenidae are grossly underrepresented as host records from Mexico, Central America and South America are scarce (12.2%). Zoropsidae/Miturgidae and Zoropsidae/Agelenidae are atypical host families for E. unifasciatus (0.3%, 0.3%) and T. ferrugineus (0.4%, 0.4%), respectively. Rabidosa rabida (Walckenaer) (Lycosidae) (rabid wolf spider) is the predominant host spider species for both E. unifasciatus (56.8%) and T. ferrugineus (58.3%).
Im Rahmen einer Untersuchung der Bahnsteige und des Gleisbereichs von insgesamt 31 Bahnhöfen des Taunus und seines Vorlandes konnten insgesamt acht Geranium-Arten nachgewiesen werden. Die bei weitem häufigste Art war G. robertianum (28 Bahnhöfe), mit weitem Abstand gefolgt von G. columbinum (10). Das bisher im Taunus nur einmal nachgewiesene G. purpureum wurde immerhin an sieben Bahnhöfen gefunden. Die weiteren angetroffenen Gerania waren G. molle (6 Bahnhöfe), G. pusillum (5) sowie G. dissectum, G. pyrenaicum und G. sanguineum (je 1 Bahnhof). Bei Letzterem handelte es sich offensichtlich um einen Kulturflüchtling. Höchstwahrscheinlich sind im Untersuchungsgebiet auch spontane Hybriden von G. purpureum und G. robertianum vorhanden.
Im Taunus konnten folgende Pflanzengesellschaften der Ordnung Agropyretalia intermedio-repentis durch Vegetationsaufnahmen belegt werden: Convolvulo arvensis-Agropyretum repentis, Cardario drabae-Agropyretum repentis, Falcario vulgaris-Agropyretum repentis, Diplotaxio tenuifoliae-Agropyretum repentis, Agropyro repentis-Rumicetum thyrsiflori, Poo compressae-Anthemidetum tinctoriae, Poo compressae-Tussilaginetum farfarae und Poa-compressa-Poa-pratensis-[Convolvulo-Agropyrion]-Gesellschaft.
Am Ufer der Rurtalsperre (Untersee) konnten im Frühherbst 2018 größere Bestände von Cardamine occulta beobachtet werden. Es handelt sich um den zweiten Nachweis an einem naturnahen Standort in Nordrhein-Westfalen. Die Ökologie und Phänologie der neophytischen Art werden diskutiert. Bisher wurden in Europa außer an Ufern des Bodensees und des Rheins sowie in Reisfeldern in Norditalien nur Vorkommen in stark anthropogen beeinflussten Lebensräumen, wie Gärtnereien, Blumenkübeln und Friedhöfen beobachtet. Es lassen sich zwei Hauptentwicklungsphasen im Spätwinter/Frühjahr und im Spätsommer/Herbst feststellen. Während an anthropogenen Standorten wie Friedhöfen zu beiden Zeiten blühende Pflanzen beobachtet werden können, beschränken sich die Vorkommen an natürlichen/naturnahen Standorten offenbar entweder wie am Bodensee auf das Winter- oder wie in Nordrhein-Westfalen auf das Sommerhalbjahr.
We provide a review of the enoplid suborder Trefusiina Siddiqi, 1983, based on morphological considerations and analyses of new and published 18S rDNA sequences. We also describe Halanonchus scintillatulus Leduc sp. nov. from the Hauraki Gulf, northern New Zealand, as well as females of Trefusialaimus idrisi Leduc, 2013 from the continental slope of New Zealand. We show for the first time that the structure of the female reproductive system of Trefusialaimus Riemann, 1974 consists of two opposed and outstretched ovaries, an unusual feature for the Enoplida. The Trefusiina did not form a monophyletic group in the 18S rDNA phylogeny due to the placement of Lauratonema Gerlach, 1953 and Trefusialaimus sequences well away from the main Trefusiina clade. However, due to generally weak Maximum Likelihood support values, we refrain from changing the classification of these taxa until more comprehensive analyses can be conducted. Our phylogenetic analysis supports the inclusion of the Trischistomatidae Andrássy, 2007 within the Trefusiina, meaning that all of the enoplid suborders now include at least some terrestrial/freshwater representatives. The Trefusiina currently comprises five families, 14 genera and 92 valid species.
Handbook of best practice and standards for 2D+ and 3D
imaging of natural history collections
(2020)
Digitising a collection is key to make it last even after the physical objects are no longer available. Almost all of the techniques currently available to digitise a natural history collection in 2D+ and 3D are listed herein. The techniques are explained in a way that even one without any knowledge on the subject may understand their principle. The strong and weak points of the techniques are discussed, and an overview of suitable collections and specimens are given for each one of them. Also, plenty of examples already digitised with each technique are provided together with the links to visualise them in 3D. After explaining all the different digitisation options, the subsequent chapters provide information on how to improve the 2D+ and 3D digital twins of the specimens and techniques are compared to each other by means of test specimens. These give a fast overview of the capabilities of the digitisation techniques. Possible solutions to avoid digitisation errors are equally provided. Lastly, the dissemination of the results and the data management of the 3D models are briefly discussed in the final chapters. Also, a large chapter is provided with several workflows that can be followed to get the best possible results.
Hemipogon s. str. (Apocynaceae: Asclepiadoideae) currently consists of three species sharing an erect herbaceous habit, narrow leaves and corona-less flowers with urceolate, internally bearded corolla, that are mainly distributed in savannahs of the Cerrado biodiversity hotspot, South America. Here, we describe and illustrate a new species of Hemipogon, H. trilobatus Bitencourt & Rapini sp. nov., from an open savannah in Chapada dos Veadeiros, Central Brazil. Hemipogon trilobatus sp. nov. differs from the other species of the genus mainly by the presence of a reduced staminal corona with 3-lobed lobes, but also by opposite leaves and triangular anthers. Distribution and habitat data, as well as a key and a comparative table to distinguish the four species currently accepted in Hemipogon s. str., are provided. Based on criteria B2ab(i,ii,iii,iv) of the International Union for Conservation of Nature (IUCN), the species is provisionally assessed as Critically Endangered.
We describe a long-unnamed Chaetopterus Cuvier, 1830 species from southern California, using a combination of DNA barcoding and detailed morphological investigation employing highresolution X-ray microtomography (micro-CT). Chaetopterus dewysee sp. nov. is not only one of the most dominant annelids in the benthic communities of the shallow end of the La Jolla submarine canyon, but also a well-established model for studying bioluminescence and has a published transcriptome. The description and naming of this southern Californian Chaetopterus is a step towards the muchneeded revision of the group’s taxonomy and towards resolving the confusion over the 'cosmopolitan' Chaetopterus variopedatus species complex. Micro-CT data showing details of both internal and external anatomy has been made freely available as the first annelid cybertype.
The functional relationships between woody vegetation, climate, soils and disturbances like fire are complex and vary greatly between continents due to historical and environmental differences. In the temperate grasslands of lowland south–eastern Australia, it is hypothesised that the extent of treelessness was influenced by Aboriginal burning practices, although this remains highly contested. This study reconstructed a multi–bioregional–scale grass/ tree boundary map across a large portion of central and northern Victoria from hundreds of historic plans, overlayed with the georeferenced observations of the earliest European accounts to test whether these grasslands were (a) more extensive than previously assumed, and (b) if there is evidence of the targeted, purposeful and frequent use of fire by Aborigines. The archival coverage was well–corroborated and identified extensive treeless 'plains' in unexpected areas compared with reconstructions based on climate–edaphic relationships alone. The historic accounts also served to shed light on the original nature of these treeless 'plains' as diverse and dynamic, and frequently dominated by Kangaroo Grass (Themeda triandra), implying a distinct influence of both frequent fire and people. However, while there is evidence of broad–acre Aboriginal fires in the collective historic accounts (including resistance to European intrusion), there remains a need for more in–depth and reliable historic case studies to clearly describe the use of fire by Aborigines that is inferred in the historic accounts studied here and commonly assumed by historians. The results lend support to treelessness driven by the dynamic interaction of 'bottom–up' and 'top–down' processes and that lowland temperate grassland distribution reconstructions across this region should be extensively corroborated or even derived exclusively from historic sources.
The scale insects (Hemiptera: Coccomorpha) are one of the most successful groups of plant-feeding arthropods. Most species of shade trees, fruit trees and ornamental shrubs are subject to scale insect attacks. Based on the review of the literature and survey results, the host plant list of the scale insects in South Korea was developed and updated. Herein, an updated list of 253 species of host plants in 71 families associated with scale insects is provided and 162 species in 15 scale insect families are listed.
The arboreal click beetle fauna (Coleoptera: Elateridae) in a lowland tropical rainforest in southern Venezuela was observed and collected by means of a tower crane for a full year. The evaluation of the elaterid assemblage is part of a general survey of Coleoptera associated with several canopy trees. The Elateridae represented the tenth most species-rich beetle family in the canopy of the crane plot and was therefore selected for a detailed analysis of host-use patterns. In total, 20 species of Elateridae with 402 adult individuals were sampled, including seven singletons. Species were either flower visiting (Aeolus Eschscholtz and Cosmesus Candèze) or fed mainly on extrafloral nectaries (Chalcolepidius Eschscholtz, Crepidius Candèze, Lacon Castelnau, Lissomus Dalman, and Semiotus Eschscholtz). The most abundant species was Aeolus sp. 1 (N = 306) feeding on flowers of nine different host-tree species. This species was found often in high abundances during the entire flowering period of a single tree species with highest abundances coinciding with the maximum of open flowers. Aeolus sp. 1 was recorded almost every month of the year moving usually from one flowering tree species to another comprising possibly the entire local population. This species showed preferences between different tree species and occurred there only at night. Tree species that supported the most species-rich elaterid assemblages were Ruizterania trichanthera (Spruce ex Warm.) Marc.-Berti (Vochysiaceae) (N = 8) and Goupia glabra Aubl. (Goupiaceae) (N = 6). Only one elaterid species with at least two collected individuals was found restricted to one tree species.
As a result of the integrative (morphology and DNA barcodes) revision of the Taiwanese species of the rove beetle genus Quedius belonging to the abnormalis group, in the subgenus Microsaurus, three valid hypogean species are reported for the fauna of this island: Quedius masuzoi Watanabe, 1989, Q. nishikawai Watanabe, 1991 and Q. adilus sp. nov. A new synonymy, Quedius masuzoi = Quedius chiangi Smetana, 1995 syn. nov., is established along with providing additional records, a larval description and bionomic information for this species. Finally, the biogeographic origin of the abnormalis group in Taiwan is discussed.
Recent shipments of aquarium plants to pet stores in five Florida counties were found to be infested with an exotic delphacid planthopper. Rearing adult males allowed identification by morphological analysis. Molecular analysis confirmed that it was the same as authoritatively identified reference specimens of the planthopper, Opiconsiva anacharsis (Fennah) (new combination) (Hemiptera: Delphacidae), first reported from Florida in 1989 and known to be established only in Broward County. The host plants, Echinodorus spp. Rich. ex Engelm.(Alismatales: Alismataceae), originally from Thailand, were sold in enclosed plastic cylinders that provided a suitable environment for maintaining the planthoppers. Attempts to trace the shipment histories to these stores suggested a circuitous multi-state pathway leading to a Broward County, Florida, business that receives aquatic plants from Southeast Asia. While the infestation of these plants may have occurred in Florida, trade in semi-emergent aquatic plants is shown to be a potential pathway for introduction for insect pests.
We honor the life and accomplishments of Michael C. Thomas with a short narrative of his professional life along with appendices listing his scientific artwork, bibliography and patronyms. This paper is the first of a Festschrift with contributed remembrances and separate papers honoring him with additional patronyms.
Ipomoea beninensis Akoègn., Lisowski & Sinsin (Convolvulaceae) is the only endemic plant known for Benin. To date, no data exist on its usages, distribution, abundance, and threats. An improved understanding of indigenous know- ledge and of local practices can provide insight into how the species could be sustainably conserved. We interviewed 114 local residents for collecting ethnobotanical and ethnoecological data in six sites known to host the species. Data were pro- cessed by calculation of descriptive statistics and variance and multivariate analyses. A total of twelve uses were reported. Among them, treatment of varicella (19%), malaria (18%) and fodder (17%) were the most recurrent. These mainly involve use of the species rootstock. Almost all respondents mentioned decline of the species in natural habitats. None of them was aware about the endemic status of the species. Consequently, negative practices toward the protection of I. beninensis were prevalent among local residents. Several conservation measures are proposed to ensure the longterm survival of I. beninensis.
A new species of the genus Mesobiotus is described from the Republic of South Africa using a traditional morphological approach (light and scanning electron microscopy) combined with molecular analysis (18S rRNA, 28S rRNA, ITS-2 and COI markers). Mesobiotus anastasiae sp. nov. differs from all known Mesobiotus species by having a unique combination of characters of the adult animals and the eggs. Adults of the new species have an oral cavity armature without elongate teeth in the second band, while the processes of the egg chorion have a basal collar and distinct rows of large pores. An updated key to the species of the genus Mesobiotus, including 66 of 70 currently described species, is given. An aquatic mite species from the Lobohalacarus weberi complex (freshwater Halacaridae) co-occurs with M. anastasiae sp. nov., suggesting that the newly described tardigrade inhabits constantly wet moss cushion habitats.
An integrative redescription of Hypsibius pallidoides Pilato, Kiosya, Lisi, Inshina & Biserov, 2011 was undertaken following a reexamination of the type material and new material using highquality light microscopy, scanning electron microscopy and methods of molecular taxonomy. Detailed morphological investigations revealed a unique complex of characters that precluded the attribution of this species to the genus Hypsibius Ehrenberg, 1848. Furthermore, phylogenetic analyses indicated the affi nity of this species within the subfamily Pilatobiinae (Hypsibiidae). Notahypsibius gen. nov. is erected for H. pallidoides and two putatively related species: H. scaber Maucci, 1987 and Ramazzottius arcticus (Murray, 1907). An emended diagnosis for the genus Pilatobius is given, while the subfamily Pilatobiinae lacks a cohesive morphological diagnosis despite representing, at the same time, a wellsupported molecular clade. Obvious controversy between the results of the morphological and molecular analyses of the phylogeny of Hypsibioidea is discussed. The distribution of morphological characters such as the claw type, organization of the bucco-pharyngeal apparatus, and egg shell sculpture type within Eutardigrada is analyzed and their phylogenetic signifi cance discussed.
In this paper we describe Macrobiotus engbergi sp. nov. and Tenuibiotus zandrae sp. nov. from Greenland. Our study has involved both classical taxonomic methods, which include morphological and morphometric analyses conducted with the use of light and scanning electron microscopy, and genetic analysis based on four molecular markers (three nuclear: 18S rRNA, 28S rRNA, ITS-2, and one mitochondrial: COI). Moreover, we re-examined the type series of Tenuibiotus voronkovi (Tumanov, 2007) as well as the original sample where the species was found and we provide new morphological data from light and scanning electron microscopy which enabled us to amend its description. Finally, we also analysed slides with animals and egg of two populations from Nordaustlandet and Edgeøya (archipelago of Svalbard, Norway) designated as T. voronkovi within its recent redescription. The results and comparisons presented in our study question the validity of this designation.
Integrative taxonomy of the genus Dyscolus (Coleoptera, Carabidae, Platynini) in Ecuadorian Andes
(2020)
The genus Dyscolus Dejean, 1831 is a highly speciose taxon of neotropical Carabidae and the major component of high-altitude ground beetle communities in the tropical Andes. The aim of this study is threefold: (i) refine the taxonomic position of the equatorial members of Dyscolus using molecular data, (ii) provide a delimitation of the species found in Ecuador in páramo and montane forest environments based on a robust combination of molecular and morphological data, (iii) describe the new species and take the nomenclatural decisions made necessary by the results of this study. The seclusion of Dyscolus from more basal platynine clades including Platynus, Batenus and Glyptolenus, is supported by a phylogenetic analysis of the COI marker. Twenty-five new species of Dyscolus, most of them microendemic, are described and illustrated: D. aquator Moret sp. nov. (Tandayapa, Pichincha), D. arauzae Moret sp. nov. (Mt Cayambe, Pichincha), D. arborarius Moret sp. nov. (Parque Nacional Yacuri, Loja), D. barragani Moret sp. nov. (Mt Ayapungu, Chimborazo), D. crespoae Moret sp. nov. (Parque Nacional Podocarpus, Zamora-Chinchipe), D. danglesi Moret sp. nov. (Parque Nacional Yacuri, Loja), D. donosoi Moret sp. nov. (Parque Nacional Podocarpus, Zamora-Chinchipe), D. eleonorae Moret sp. nov. (Cotopaxi and Pichincha provinces), D. famelicus Moret sp. nov. (Papallacta, Napo), D. giselae Moret sp. nov. (Reserva Otonga, Cotopaxi), D. globoculus Moret sp. nov. (Parque Nacional Podocarpus, Zamora-Chinchipe), D. gobbii Moret sp. nov. (Guamaní and Mt Antisana, Pichincha), D. incommunis Moret sp. nov. (Tandayapa, Pichincha), D. marini Moret sp. nov. (Parque Nacional Podocarpus, Loja), D. piscator Moret sp. nov. (Guamaní, Napo), D. placitus Moret sp. nov. (Guamaní, Napo), D. ravidus Moret sp. nov. (Parque Nacional Podocarpus, Loja), D. rivinus Moret sp. nov. (Reserva Otonga, Cotopaxi), D. rugitarsis Moret sp. nov. (Parque Nacional Yacuri, Loja), D. ruizi Moret sp. nov. (Parque Nacional Podocarpus, Loja and Zamora), D. salazarae Moret sp. nov. (Parque Nacional Podocarpus, Loja), D. silvestris Moret sp. nov. (Papallacta, Napo), D. sulcipedis Moret sp. nov. (Parque Nacional Yacuri, Loja), D. verecundior Moret sp. nov. (Mt Illiniza and Mt Corazón, Pichincha) and D. verecundissimus Moret sp. nov. (Mt Chimborazo, Chimborazo). Dyscolus palatus Moret, 1998 is newly synonymized with D. denigratus (Bates, 1891). We demonstrate the subgenus Hydrodyscolus Moret, 1996 to be polyphyletic and therefore consider it a junior synonym of Dyscolus Dejean, 1831.
Two new species, Hyphessobrycon frickei Guimarães, Brito, Bragança, Katz & Ottoni sp. nov. and H. geryi Guimarães, Brito, Bragança, Katz & Ottoni sp. nov., are herein described, based on seven different and independent species delimitation methods, and on molecular and morphological characters, making the hypothesis of these new species supported from an integrative taxonomy perspective. They belong to the “Rosy tetra” clade, which is mainly characterized by the presence of a dark brown or black blotch on the dorsal fin and the absence of a midlateral stripe on the body. These two new species are distinguished from the other members of this clade mainly by the arrangement, shape and color pattern of humeral and dorsal-fin spots, as well as by other characters related to scale counts and body pigmentation. The placement of the new species within the “Rosy tetra” clade was based on the combination of morphological character states mentioned above and corroborated by a molecular phylogenetic analysis using the mitochondrial gene cytochrome oxidase subunit 1. In addition, a new clade (here termed Hyphessobrycon copelandi clade) within the “Rosy tetra” clade is proposed based on molecular data, comprising H. copelandi, H. frickei sp. nov., H. geryi sp. nov. and a still undescribed species. Our results corroborate the occurrence of hidden species within the “Rosy tetra” clade, as suggested by previous studies.
Jumping bristletail (Insecta: Apterygota: Microcoryphia) records in the southeastern United States
(2020)
Few records of Microcoryphia exist for the southeastern United States, with named species being reported only from Arkansas, Tennessee, and the mid-Atlantic states, and with an unnamed species being reported from Georgia. Records are here provided from 291 specimens housed in the Mississippi Entomological Museum, including ten new species-level state records. This is also the first published report of the order Microcoryphia from Alabama and Mississippi. Species include the machilids Pedetontoides atlanticus Mendes in Alabama, Arkansas, Georgia, Mississippi, and North Carolina; Pedetontus cf. atlanticus in Kentucky; Pedetontus (Verhoeffilis) gershneri Allen in Arkansas; and Pedetontus (Pedetontus) saltator Wygodzinsky and Schmidt in Mississippi and North Carolina; and the meinertellid Machiloides banksi (Silvestri) in Alabama, Arkansas, Mississippi, and North Carolina.
Taxonomic work on the land snail genus Sarika Godwin-Austen, 1907 in Cambodia is scarce. A total of three species were recognized from Cambodia prior to this study. However, their taxonomic descriptions were based mainly on shell morphology, with limited genital data. To address this knowledge gap, we opportunistically surveyed for land snails in Cambodia. Our inventory yielded four species of Sarika – one recognized species, Sarika bocourti (Morelet, 1875), from Battambang Province and three new species, Sarika khmeriana Pholyotha & Panha sp. nov., Sarika lactoconcha Pholyotha & Panha sp. nov. and Sarika nana Pholyotha & Panha sp. nov. from Kampot and Takeo Provinces in southern Cambodia. Our discovery involves the first species of Sarika to be described from Cambodia in more than a century highlights the extent to which the diversity of Cambodian land snails remains to be discovered. The status of two species, Sarika benoiti (Crosse & Fischer, 1863) and Sarika resplendens (Philippi, 1846), is at present ambiguous because no material identifiable as these species was found in recent extensive surveys. Although S. bocourti was recently collected from Cambodia, its taxonomic position remained unclear due to a lack of living specimens. Detailed descriptions and illustrations of living animals, shell morphology and reproductive anatomy are provided, and a map showing their distributions is given.
Recent studies have shown that the speciose Holarctic genera of Leiobunum C.L. Koch, 1839 and Nelima Roewer, 1910 are polyphyletic taxa, and therefore, the traditional diagnostic characters for these European genera of Leiobuninae Banks, 1893 (respectively, the presence or absence of tubercle rows on leg coxae) are unsuitable. We present the description of Leiolima iberica gen. et sp. nov., a new endemic harvestman from the north-western part of the Iberian Peninsula. The newly established genus shows intermediate characters between Leiobunum and Nelima. In addition, the new genus is characterized by shorter legs compared to Leiobunum and the presence of trichomes on all leg femora and pedipalpal patellae, a structure that is absent in all other western Palearctic genera of the subfamily Leiobuninae.
Many aspects of the biology of Genoplesium baueri R.Br. (Orchidaceae) an endangered terrestrial orchid endemic to New South Wales, Australia, remain unknown. In this study observations were made on (1) plant morphology; (2) the biology of the fruit and seeds; (3) the biology of the plant tuber and the spatial patterning of emergent plants ; (4) the morphology of the pollen and the identity of pollen vectors and (5) to develop a preliminary description of the lifecycle of the orchid, by carrying out annual surveys of two key Genoplesium baueri populations in northern Sydney, for a 12-year period and collecting data on fruits, tubers and pollinators opportunistically. Individual plants cannot be tracked from year to year. We observed that each emergent plant produces a tubular leaf and an inflorescence of 1-15 non-resupinate flowers. Fruit capsules contained numerous tiny seeds, which were slightly larger than seeds of a closely related species, Corunastylis filiformis. The papillose surface of mature tubers of Genoplesium baueri differed greatly from the smooth, spherical tubers of Corunastylis fimbriata and is likely to be the site of orchid mycorrhizae. The occurrence of clumps of closely-packed, variously-sized tubers, each subtending single Genoplesium baueri plants, warrants investigation as development by vegetative increase at the tuber level provides one of several possible explanations. The morphology of the pollinarium and evidence of Chloropid fly-mediated pollination was observed. Our better understanding of the natural history and biology of Genoplesium baueri will contribute to orchid systematics and help inform management decisions regarding this species to ensure its persistence into the future.
Three species of Lophogastrida and eight Mysida are documented for samples from 5161–5497 m bottom depth in the Angola Basin. Previously known latitudinal ranges are extended southward for five species, and bathymetric ranges extended beyond 5000 m for six species. Upon revision of the subfamily Petalophthalminae (Mysidae), four species previously attributed to the genus Petalophthalmus are integrated into Ipirophthalmus gen. nov. as I. liui gen. et comb. nov., I. caribbeanus gen. et comb. nov., I. oculatus gen. et comb. nov., and I. macrops gen. et comb. nov., mainly based on the structure of eyes and presence of setae on the telson. Petalophthalmus cristatus sp. nov. is described based on its reduced cornea and the structure of eyestalks, rostrum, mandibles, and telson. The structure of mouthparts, foregut and maxillipeds suggests an omnivorous mode of life. The diagnosis of the tribe Calyptommini (Mysidae: Erythropinae) is widened to cover the 3-segmented, uniramous fourth male pleopod and the non-incised eyeplate with horn-like rudiments of eyestalks in Abyssomysis cornuta gen. et sp. nov. The structure of mandibles, foregut, and second maxilliped suggest detritus feeding in this species. Keys to the Calyptommini and Petalophthalminae are given.
A new jumping spider genus, Manzuma gen. nov. (Salticidae Blackwall, 1841), is described, type species is Manzuma nigritibia (Caporiacco, 1941). Aelurillus reconditus Wesołowska & van Harten, 1994 is synonymized with Rafalus nigritibiis (Caporiacco, 1941). Four new combinations are proposed: M. jocquei gen. et comb. nov. (ex Aelurillus), M. kenyaensis gen. et comb. nov. (ex Langelurillus), M. lympha gen. et comb. nov. (ex Rafalus) and M. nigritibia gen. et comb. nov. (ex Rafalus). Three species, M. botswana gen. et sp. nov. (♂♀, Botswana and Republic of South Africa), M. petroae gen. et sp. nov. (♂♀, Republic of South Africa) and M. tanzanica gen. et sp. nov. (♂, Tanzania), are described. The male of M. kenyaensis gen. et comb. nov. and female of M. lympha gen. et comb. nov. are described for the first time. A new aelurilline synapomorphy is proposed. Identification key for males is provided.
Morphological characters support the description of two new species of Orchidaceae from New Caledonia: Dendrobium butinii M.Pignal & Munzinger sp. nov. and Dendrobium letocartiorum Munzinger & M.Pignal sp. nov. The lectotypes of Dendrobium camaridiorum Rchb.f. and D. crassifolium Schltr. are designated here. A leaf anatomical study was conducted and provided useful characters to distinguish the five New Caledonian graminoid Dendrobiineae species. Two identification tools are provided: an anatomical key for sterile material of grass-like Dendrobiineae and a morphological key for the New Caledonian graminoid Dendrobium. We propose preliminary conservation assessments with IUCN criteria for the new taxa.
We describe three new parastenocaridid: Cottarellicaris sanctiangeli Bruno & Cottarelli sp. nov., Stammericaris vincentimariae Bruno & Cottarelli sp. nov. and Proserpinicars specincola Bruno & Cottarelli sp. nov., collected in the pools of five different caves located in Calabria (Southern Italy). We conducted a phylogenetic analysis based on the mitochondrial COI and ribosomal 18S sequences of C. sanctiangeli sp. nov. and S. vincentimariae sp. nov., and of four more species of Stammericaris and one Proserpinicaris available from literature. Based on the molecular study, the specimens of C. sanctiangeli sp. nov. are clearly separated from the species belonging to the closely-related genus Stammericaris. The morphological and molecular data indicate that the genera belonging to the two subfamilies Parastenocaridinae and Fontinalicaridinae form two monophyletic and distinct clades, thus supporting their status. We also provide insights on the genus Proserpinicaris based on morphological data only; in particular, the most important synapomorphic character of the genus, i.e., the taxonomic value of the hyaline structure inserted on the anterior surface of the male leg 4 basis, is discussed based on the development of the P4 endopod, as observed in the last copepodid stage of some species of this genus. Finally, we widen the biogeographic and ecological knowledge of the three genera.
