The chelodesmid genus Dibolostethus Hoffman, 2009, the sole member of the tribe Dibolostethini, is reviewed. The genus contains the type species D. sicarius Hoffman, 2009 known only from the Los Rios Province, Ecuador, and two new species from the Tropical Andes, D. inopinatus Means, Bouzan & Ivanov sp. nov. from the Morona-Santiago Province, Ecuador and D. kattani Means, Bouzan, Martínez-Torres & Ivanov sp. nov. from the Valle del Cauca Department, Colombia. We redescribe D. sicarius and provide a revised diagnosis of the genus, images of diagnostic morphological characters, and a key to the males of Dibolostethus. In addition, we provide a summary and a distribution map of the Chelodesmidae of the Tropical Andes Biodiversity Hotspot.
A new spionid polychaete, Prionospio expansa sp. nov., collected from the intertidal habitat of the Yellow Sea in Korea, is described. The new species is closely related to P. japonica Okuda, 1935 from Northeast Asia both morphologically and genetically. They share four pairs of branchiae which are cirriform and apinnate, whereas the new species differs from P. japonica in the length of the branchiae, expansion of the anteriormost body, and size of the first notopodial postchaetal lamellae. Herein, a detailed description and illustrations of P. expansa sp. nov. are provided, with molecular data for three gene fragments: mitochondrial cytochrome c oxidase subunit I, 16S ribosomal DNA (rDNA), and nuclear 18S rDNA. A phylogenetic analysis was conducted based on mitochondrial and nuclear gene fragments.
Iberian material originally identified as Hincksina flustroides is revised and five different species are now identified: the Atlantic species Hincksina flustroides is present to the NW of the Iberian Peninsula, whilst the Mediterranean species Hincksina synchysia is here reported for the first time in Iberian waters. Two new species of Hincksina are described, one from the Strait of Gibraltar area, and another from the Alboran Sea, whereas another colony from this area actually corresponds to Hincksina longispinosa. A new description of Electra angulata is given, based on the original and other historical material, as well as on newly collected colonies. The taxonomic position of the species in the genus Arbopercula is discussed, and the diagnosis of the genus itself is amended. Finally, a new species of Caberea is described from deep waters off the north Iberian coast.
A new genus, Plesioxylion Liu & Beaver gen. nov., is described for Amintinus gambianus Borowski, 2018 from West Africa with a more detailed description and new records of both sexes. We also provide a key to the ten Afrotropical genera in the tribe Xyloperthini Lesne, 1921 as the baseline information for a future study.
In this study, we revise the taxonomy of the endemic Mexican genus Ceratotrupes Jekel, 1865. It comprises three species, distributed in the Sierra Madre Occidental and Trans-Mexican Volcanic Belt (Ceratotrupes fronticornis (Erichson, 1847) and Ceratotrupes bolivari Halffter & Martínez, 1962), and the Sierra Madre del Sur (Ceratotrupes sturmi (Jekel, 1865)). We confirm C. mniszechi (Jekel, 1865) as a junior subjective synonym of C. sturmi. The examination of the holotype of C. sturmi and specimens recently collected in the Sierra Sur de Oaxaca (Oaxaca) and Omiltemi (Guerrero) allowed us to identify and describe a new species, Ceratotrupes gonzaloi sp. nov. from Omiltemi, Guerrero. We redescribe the morphology of C. sturmi and provide a diagnostic key to the four members of the genus Ceratotrupes. Photographs of the habitus and male genitalia of the four species, a distribution map, and observations on their ecology and biogeography are provided.
The railway cutting near Oberrödinghausen at the northern margin of the Rhenish Mountains is the cardinal section for the investigation of Early Tournaisian (Early Carboniferous; Mississippian) ammonoids. The ammonoids from the Hangenberg Limestone (= Gattendorfia Limestone) of this and neighbouring outcrops are revised here, using the historical collections as well as undescribed new material. The ammonoid assemblages are composed of a total of 67 species, which occur in four successive ammonoid zones. The assemblages are composed of predominant prionoceratids (Order Goniatitina) with the twenty genera Mimimitoceras (two species), Globimitoceras (one species), Paragattendorfia (two species), Kornia (three species), Stockumites (eleven species), Acutimitoceras (two species), Costimitoceras (one species), Nicimitoceras (four species), Imitoceras (one species), Voehringerites (one species), Gattendorfia (eight species), Zadelsdorfia (two species), Kazakhstania (one species), Gattenpleura (one species), Weyerella (three species), Hasselbachia (three species), Paprothites (five species), Pseudarietites (three species), Rodingites (two species), Paralytoceras (one species) as well as subordinate eocanitids (Order Prolecanitida) with the genera Eocanites (eight species) and Nomismocanites (one species). The new genera Rodingites gen. nov. and Nomismocanites gen. nov. as well as the new species Mimimitoceras perditum sp. nov., Kornia fibula sp. nov., Kornia acia sp. nov., Stockumites parallelus sp. nov., Stockumites voehringeri sp. nov., Acutimitoceras ucatum sp. nov., Acutimitoceras paracutum sp. nov., Imitoceras initium sp. nov., Gattendorfia rhenana sp. nov., Gattendorfia bella sp. nov., Gattendorfia valdevoluta sp. nov., Gattendorfia schmidti sp. nov., Gattendorfia corpulenta sp. nov., Gattendorfia immodica sp. nov., Zadelsdorfia oblita sp. nov., Weyerella lenis sp. nov., Hasselbachia erronea sp. nov., Paprothites beckeri sp. nov., Paprothites kullmanni sp. nov., Eocanites delicatus sp. nov. and Nomismocanites raritas gen. et sp. nov. are described from Oberrödinghausen. Mimimitoceras mina sp. nov., Stockumites marocensis sp. nov., Zadelsdorfia zana sp. nov. and Kazakhstania kana sp. nov. are newly named for material from the Anti-Atlas of Morocco.
The early Tournaisian (Early Carboniferous; Mississippian) ammonoids from the classical abandoned limestone quarry of Gattendorf (Upper Franconia) are revised, using the historical collections as well as so far undescribed material. The ammonoid assemblage is composed of prionoceratid ammonoids of the six genera Mimimitoceras, Paragattendorfia, Stockumites, Acutimitoceras, Gattendorfia and Gattenpleura, which indicate a stratigraphic position near the Devonian–Carboniferous boundary in the earliest Carboniferous. The new species Stockumites hofensis sp. nov. and S. nonaginta sp. nov. are described.
The number of currently described species of Afrotropical parasitoid wasps does not reflect the true species diversity. One of the most severely understudied parasitoid wasp groups is Ceraphronoidea. In this first study on Afrotropical mainland Ceraphronoidea in more than 20 years, which is also the first ever taxonomic monograph focusing on Ceraphronidae, we describe 88 new species of Ceraphronidae (85 new species) and Megaspilidae (3 new species) from Kakamega Forest (Kenya), Mt. Kilimanjaro (Tanzania) and Ivindo NP (Gabon): Aphanogmus abaluhya sp. nov., A. ashitakai sp. nov., A. idakho sp. nov., A. ikhongamurwi sp. nov., A. isiukhu sp. nov., A. kakamegaensis sp. nov., A. lateritorum sp. nov., A. mangimelii sp. nov., A. mariae sp. nov., A. mashariki sp. nov., A. nehbergi sp. nov., A. njia sp. nov., A. vestrii sp. nov., A. yala sp. nov. (all clavicornis species group), A. dimidiatus sp. nov., A. fraterculus sp. nov., A. guenteri sp. nov., A. kakakili sp. nov., A. kisiwa sp. nov., A. maua sp. nov., A. morriconei sp. nov., A. ndefu sp. nov., A. ngai sp. nov., A. nikii sp. nov., A. pilosicoxa sp. nov., A. rafikii sp. nov., A. robustus sp. nov., A. simbai sp. nov., A. taji sp. nov., A. ukanda sp. nov. (all fumipennis species group), A. campanula sp. nov., A. kikuyu sp. nov., A. pagoda sp. nov. (all tenuicornis species group), Ceraphron banda sp. nov., C. brashi sp. nov., C. breviharpis sp. nov., C. breviscapus sp. nov., C. buyangu sp. nov., C. chemositi sp. nov., C. cingulum sp. nov., C. clavatumeris sp. nov., C. digiti sp. nov., C. eaerendili sp. nov., C. ekero sp. nov., C. ellae sp. nov., C. eulbergi sp. nov., C. herreni sp. nov., C. hitagarciai sp. nov., C. insolitus sp. nov., C. isecheno sp. nov., C. isukha sp. nov., C. ivindoensis sp. nov., C. kaharabu sp. nov., C. kaimosiensis sp. nov., C. kakamegaensis sp. nov., C. kidole sp. nov., C. kimathii sp. nov., C. lirhanda sp. nov., C. longiharpis sp. nov., C. longisetae sp. nov., C. longumerunus sp. nov., C. maathaiae sp. nov., C. malava sp. nov., C. mamamutere sp. nov., C. metapleuralis sp. nov., C. mikoi sp. nov., C. mwekaensis sp. nov., C. nandi sp. nov., C. nzoia sp. nov., C. onesimusi sp. nov., C. pilosiharpis sp. nov., C. pleurosulcus sp. nov., C. reinholdi sp. nov., C. salazar sp. nov., C. sataoi sp. nov., C. semira sp. nov., C. sungura sp. nov., C. tenuimeris sp. nov., C. tiriki sp. nov., C. trietschae sp. nov., Cyoceraphron dhahabudorsalis sp. nov., C. harpe sp. nov., C. invisibilis sp. nov., C. kahawia sp. nov., C. njano sp. nov. (all Ceraphronidae), Conostigmus kijiko sp. nov., C. koleo sp. nov., and Dendrocerus wachagga sp. nov. (all Megaspilidae). In addition, we describe four species of Aphanogmus and five species of Ceraphron without formal naming. A neotype is designated for Dendrocerus anneckei Dessart, 1985 (Megaspilidae). With these new species we more than double the number described from the Afrotropical mainland (65 vs 153). The species numbers found allow us to estimate the real worldwide species number of Ceraphronoidea as being roughly 12 000–21 000, i.e., 16–29 times the number of the currently described species (~730, including the species described herein). This study is meant to highlight that it is necessary and also possible to study the parasitoid wasps of tropical regions and provide momentum for exploring the diversity of small and diverse insect groups in the Afrotropics and elsewhere while also providing the basic knowledge that is much needed for protecting biodiversity and understanding evolution and the networks of life on earth. All described species are diagnosed and illustrated, with focus on the male genitalia. Furthermore, we provide an identification key to males of Afrotropical Ceraphronidae.
We provide a floristic account for the Begoniaceae of Peru. The family is represented in Peru by 76 species, which are all members of the genus Begonia and represent eighteen sections. Twelve new species are described: B. condorensis Jara & Moonlight sp. nov., B. deltoides Moonlight sp. nov., B. huancabambae Moonlight sp. nov., B. imbrexiformis Moonlight sp. nov., B. longinqua Moonlight sp. nov., B. longitepala Moonlight sp. nov., B. nunezii Moonlight sp. nov., B. occultata J.P.Allen & Moonlight sp. nov., B. pedemontana Moonlight sp. nov., B. serratistipula Moonlight sp. nov., B. vargasii Moonlight sp. nov. and B. yuracyacuensis Moonlight sp. nov. We also provide four new records for the country: B. andina Rusby, B. brandbygeana L.B.Sm. & Wassh., B. neoharlingii L.B.Sm. & Wassh. and B. unilateralis Rusby. We provide an identification key to all species. The ecology, distribution, and conservation status of all Peruvian Begonia species are discussed, including provisional IUCN threat assessments. Most species are illustrated by either historical illustrations, contemporary photographic plates, or line drawings. Twenty-six names are newly synonymised including fifteen previously accepted species, and we designate eighty-three lectotypes, four neotypes, and four epitypes.
The fauna of Loricifera along a north-south longitudinal transect following the Atacama Trench was explored. Whereas no loriciferans were collected from the actual trench, the continental slope and surrounding abyssal plains yielded two species of Rugiloricus and two of Pliciloricus. All four species are considered as new to science, but only one of them could be formally described. The new species, Pliciloricus ukupachaensis sp. nov., is closely related with the North Atlantic Pliciloricus leocaudatus, and the two species share different morphological traits, including an enlarged anal field with conspicuous pentagonal and hexagonal fields formed by strong, cuticular ridges. Among other peculiar traits, the new species is characterised by having strongly reduced trichoscalid plates and no double trichoscalids. Comparison with previously published, unidentified specimens suggests that the new species’ distributional range might reach as far as Oregon off the US west coast.
The North American-Caribbean genera Pholcophora Banks, 1896 and Tolteca Huber, 2000 are representatives of Ninetinae, a group of small, cryptic, and thus poorly known pholcid spiders. We present the first comprehensive revisions of the two genera, including extensive SEM data and descriptions of seven new species from Mexico (Pholcophora mazatlan Huber sp. nov., P. papanoa Huber sp. nov., P. tehuacan Huber sp. nov., Tolteca huahua Huber sp. nov., T. manzanillo Huber sp. nov., T. oaxaca Huber sp. nov., and T. sinnombre Huber sp. nov.). We add new CO1 sequences of nine species to previously published molecular data and use these for a preliminary analysis of relationships. We recover a North American-Caribbean clade including ‘true’ (mainland) Pholcophora, Tolteca (Mexico), and a Caribbean clade consisting of the genus Papiamenta Huber, 2000 (Curaçao) and Caribbean ‘Pholcophora’. First karyotype data for Tolteca (2n♂ = 13, X1X2Y and 15, X1X2Y, respectively) reveal a strong reduction of the number of chromosome pairs within the North American-Caribbean clade, and considerable karyotype differentiation among congeners. This agrees with considerable CO1 divergence among species of Tolteca but contrasts with very inconspicuous morphological divergence. Environmental niche analyses show that the widespread P. americana Banks, 1896 (western USA, SW Canada) occupies a very different niche than its Mexican congeners and other close relatives. Caribbean taxa also have a low niche overlap with ‘true’ Pholcophora and Tolteca, supporting the idea that Caribbean ‘Pholcophora’ are taxonomically misplaced.
Recently, it has been hypothesized that the wide distribution of A. fiuzai Salles & Lugo-Ortiz is due to a wide diagnosis and conflicting keys. The same arguments can be applied to A. kallawaya Nieto. In order to test this hypothesis, we revised the type material of A. fiuzai, literature of A. kallawaya, and part of the recorded specimens in Brazil. As a result, three new species from previous records are recognized: Apobaetis pasternakae sp. nov., former A. fiuzai in Amazonas, Roraima and Maranhão states; Apobaetis jaquelinae sp. nov., former A. fiuzai in Rondônia State; Apobaetis luanae sp. nov., former A. kallawaya in Rondônia State. The new data showed that A. fiuzai does not occur in the Amazon Biome and A. kallawaya does not occur in Brazil. Records of A. fiuzai that could not be reviewed in this study are treated as putative and should be evaluated in the light of the new evidence. We also studied the intraspecific variation in A. fiuzai and A. pasternakae sp. nov. The pigment pattern of the nymphs was not considered a robust characteristic for the species differentiation due to the wide variation in and between populations, and interspecific similarity of many features. On the other hand, classical morphological characters such as mouthparts, legs, spines of terga, paraproct and caudal filaments have minimal variation, stable and reliable for specific identification.
Fourteen species of the subgenus Sinotipula (Diptera, Tipulidae) were previously known to occur in China. Here four species are described and illustrated as new to science: Tipula (Sinotipula) drolma sp. nov., T. (S.) forcipicauda sp. nov., T. (S.) heminga sp. nov. and T. (S.) longiloba sp. nov. The following three species are redescribed: T. (S.) exquisita Alexander, 1935, T. (S.) hobsoni Edwards, 1928 and T. (S.) wardi Edwards, 1928, and a key to the species of Tipula (Sinotipula) from China is presented. We also give a new replacement name for Tipula (Vestiplex) bucera Yang, Li, Pan, Liu & Yang, 2021, i.e., T. (V.) curvicornis nom. nov.
Specimens of Deuteraphorura collected in 11 Georgian caves were analysed morphologically and molecularly based on the COI gene barcode region. Two molecular delimitation methods revealed four species (MOTUs); however, only two of them were distinguished morphologically and are described in this paper as new to science. Both new species, D. colchisi sp. nov. and D. kozmani sp. nov., belong to the group with a pseudocellus on the first thoracic tergum; the differential diagnosis table to this species group is provided. The potential of the Caucasus as a hotspot region of subterranean biodiversity and evolution centre of subterranean animals is discussed.
The ant genus Temnothorax Mayr, 1861 (Myrmicinae, Crematogastrini) is diverse with 498 species described. Species are distributed predominately within the northern hemisphere with species richness decreasing closer to the tropics; contrary to other ant genera overall. In Southeast Asia, richness is relatively low and knowledge on the genus remains fragmentary, likely due to poor sampling efforts compared to temperate regions. Here, using specimens from recent sampling efforts, Temnothorax is reported for the first time from the Hong Kong Special Administrative Region. Two new species, T. barrettoi Hamer & Guénard sp. nov. and T. haveni Lee, Hamer & Guénard sp. nov., are described based on qualitive morphological characters, with additional morphometric data also gathered. An updated key, as well as a distributional checklist of Temnothorax species from mainland China is provided. We suggest that the two new species are likely arboreal based on our collections, however, further arboreal sampling is necessary to confirm this hypothesis. We hope this study may spurn effort to generate further information on sub-tropical Chinese Temnothorax species.
Crenicichla is the largest and most widely distributed genus of Neotropical cichlids. The Crenicichla mandelburgeri species complex from the Middle Paraná departs from the ancestral and predominant ecomorphology of the large genus and shows parallel evolution of ecomorphs both within the complex and also to the unrelated C. missioneira species complex from the Uruguay River. Here, we formally describe a new species pair from the C. mandelburgeri species complex that has evolved a parallel morphological and ecological dichotomy to another species pair and also to species in the unrelated C. missioneira species complex. The new species pair is endemic to a single tributary (the Piray Guazú) of the Middle Paraná River where it is sympatric and partly syntopic. Mitochondrial DNA phylogeny shows the two new species as distantly related within the C. mandelburgeri species complex, each with a sister species in the Iguazú rather than in the neighbouring Paraná River tributaries. Nuclear DNA analyses demonstrate their sister-group relationship, which is however complicated by the reticulated origin of one of the new species. We present determination keys for all the currently formally described species of the C. mandelburgeri species complex including the new species described here.
A new species of Apseudidae is described from a submarine canyon in the Mediterranean Sea, Leviapseudes tethys sp. nov. The species was sampled at 600 m depth on deep muddy sand. The new species is characterized by the presence of processes on both sides of the rostrum, a pinnate seta on the inner distal margin of the maxillipedal endite, smooth distal spines of the labium palp, two spines on the cheliped basis, three ventral spines on pereopod 1 basis and an unarticulated pleopod exopod. This is the second species and the third record of the genus in the Mediterranean Sea, and raises the number of tanaid species known from the deep Mediterranean Sea to a total of 16. The diagnosis of the genus is amended in light of the new data and re-evaluation of previous works. The new species presents a set of characters that provide novel insights to understanding the diversity and taxonomy of the Leviapseudinae, as well as their geographic distribution. Finally, a list of all deep-sea Tanaidacea known in the Mediterranean Sea is provided.
Metafruticicola is a diverse land snail genus inhabiting the north-eastern Mediterranean region from S Albania to Israel. In this study, we describe Metafruticicola kavafis sp. nov., a new species for science from Kasos Island. We also focus on the reproductive system of steno-endemic species and subspecies of the genus from small islands of the Aegean Archipelago, whose anatomy was previously completely unknown. These species are M. crassicosta, M. pieperi, M. coartata gemina and M. nicosiana conciliatrix. For the latter subspecies, only the outlines of the genitalia were previously given. Additionally, we investigated in detail for the first time the genital anatomy of M. nicosiana nicosiana from Cyprus. Hitherto, information on the genital apparatus of this subspecies was based on sparse data derived from sexually immature specimens. These new anatomical data contribute to a plethora of controversies concerning the subgeneric division of Metafruticicola, which was based solely on conchological features and especially the microsculpture of the teleoconch. We suggest that the current subgeneric division of the genus should be abandoned.
The weevil genus Cryptolarynx Van Schalkwyk, 1966 is endemic to the Northern and Western Cape provinces of South Africa. The two previously known species of the genus, C. vitis (Marshall, 1957) and C. estriatus (Marshall, 1957), have an aberrant globular body and head shape, which has made it difficult to place the genus into the classification systems of the Curculionoidea. This paper presents the description of 21 new species of Cryptolarynx from South Africa (C. subglaber Haran sp. nov., C. squamulatus Haran sp. nov., C. muellerae Haran sp. nov., C. hirtulus Haran sp. nov., C. robustus Haran sp. nov., C. namaquanus Haran sp. nov., C. carinatus Haran sp. nov., C. variabilis Haran sp. nov., C. pyrophilus Haran sp. nov., C. pilipes Haran sp. nov., C. armatus Haran sp. nov., C. falciformis Haran sp. nov., C. oberprieleri Haran sp. nov., C. spinicornis Haran sp. nov., C. cederbergensis Haran sp. nov., C. homaroides Haran sp. nov., C. marshalli Haran sp. nov., C. endroedyi Haran sp. nov., C. oberlanderi Haran sp. nov., C. san Haran sp. nov., and C. luteipennis Haran sp. nov.) and of one new genus and species, Hadrocryptolarynx major Haran gen. et sp. nov., also from South Africa. A redescription of the genus Cryptolarynx is provided to incorporate the characters of the new species. The plant genus Oxalis (Oxalidaceae) is recorded as larval host for several species of Cryptolarynx and for Hadrocryptolarynx Haran gen. nov., as their larvae develop in the subterranean bulbs of members of the genus, and the egg, larva and pupa of C. variabilis are described. The characters of the Cryptolarynx larva confirm that Cryptolaryngini are an early-diverging group of Curculionidae, with a placement among taxa currently classified in the subfamily Brachycerinae sensu lato, and although their exact taxonomic position remains unresolved, some larval characters, and also pupal ones, suggest a close relationship between Cryptolaryngini and Stenopelmus Schoenherr. Potential use of species of Cryptolarynx in the biological control of weedy South African species of Oxalis is discussed.
Four new species and one new genus of Lamiinae (Coleoptera: Cerambycidae) are described: Nyssodrysilla humeralis new species (Acanthocinini), from Paraguay; Atrypanius schmidi new species (Acanthocinini), from Paraguay; Chicanatonus hovorei, new genus, new species (Acanthocinini), from Mexico; Euryestola transversa new species (Calliini), from Ecuador. The following new combinations are established: Leiopus convexus Melzer, 1934 is transferred to Hyperplatys Haldeman, 1847; Leiopus floccidus Erichson, 1847 is transferred to Anisopodus White, 1855; Leiopus marcelamonneae Audureau and Demez, 2015 and L. pleuriticus White, 1855 are transferred to Atrypanius Bates, 1864. Leiopus histrionicus Gistel, 1848 is newly synonymized with Eutrypanus dorsalis (Germar, 1823). The formal transference of Leiopus soricinus Fairmaire and Germain, 1859 to Lepturges (Lepturges) Bates, 1863, forgotten in recent catalogs and checklists, is reinforced. Atrypanius marcelamonneae new combination is excluded from the Paraguayan fauna. Euryestola cribrata (Bates, 1881) is newly recorded from Panama. Keys to species of Nyssodrysilla Gilmour, 1962 and Euryestola Breuning, 1940 are provided. The occurrence of Colobothea naevia Bates, 1865 in Ecuador is confirmed. Colobothea olivencia Bates, 1865 is newly recorded from Ecuador and from the Brazilian states of Pará and Ceará; variation in the pubescent pattern on the pronotum of this species is reported. Four new species and one new genus of Lamiinae (Coleoptera: Cerambycidae) are described: Nyssodrysilla humeralis new species (Acanthocinini), from Paraguay; Atrypanius schmidi new species (Acanthocinini), from Paraguay; Chicanatonus hovorei, new genus, new species (Acanthocinini), from Mexico; Euryestola transversa new species (Calliini), from Ecuador.

The Asterolecaniidae (Hemiptera: Coccomorpha), known as pit scales, are currently represented by 11 genera and 52 species in the Neotropical region, and by five species in Argentina. The goal of this study is to review and update the information currently known about the biodiversity of Asterolecaniidae in Argentina. We describe Argenta Granara de Willink new genus, Argenta eduardoi Granara de Willink new species, Mycetococcus ligae Granara de Willink new species, and Sclerosococcus williamsi Granara de Willink new species; an illustration of Pollinia pollini (Costa) is also included; the species Asterolecanium puteanum Russell and Russellaspis pustulans (Cockerell) are noted for the first time in Argentina. Dichotomous keys to the genera of Asterolecaniidae and the species of Asterolecanium Targioni-Tozzetti, Mycetococcus Ferris, and Sclerosococcus McKenzie in Argentina are presented. This work increases the number of known species in Argentina to ten.

We studied the slides of Nipaecoccus viridis (Newstead) (Hemiptera: Pseudococcidae) deposited in the Florida State Collection of Arthropods and provided specimen label data, including geographical location, global positioning system coordinates when available, host plant, collector name, adult females/immature stages, sex of specimens on respective slides, number of slides, and collection date. In addition, we discuss its first record from Florida ornamental landscape and two most recent new host records of the species on commercial crops, including blueberries and hemp. These data will help regulatory agencies slow the spread of this pest inside and outside of Florida.

Two new genera, Skelleyus Opitz and Divulgoatus Opitz (Coleoptera: Cleridae: Enopliinae), show unusual antennal development. Funicular antennomeres become shorter as they approach an extensive capitulum. This study involves three taxa, Skelleyus leavengoodi Opitz, new species, Divulgoatus kelleri Opitz, new species, and Divulgoatus discrepans (Gorham).

Bicellonycha amoena (Gorham, 1880) (Coleoptera: Lampyridae) usually flies one meter above ground level over grass, water, or open areas, where males produce a simple single flash every 2–4 seconds, having their most active flashing period from mid to late dusk and early night. In addition, nothing else is known about the behavior of this species. We conducted field observations at the “Mayan Golf Club” in Guatemala Department, and Santiago Sacatepéquez, Sacatepéquez Department, Guatemala; and analyzed B. amoena flashes with a spectroscope. Fireflies displayed a lime-green bioluminescence color. The male flashing activity began ~30 minutes after sunset and lasted approximately 70 minutes. For B. amoena, the spectral composition of the flash is intermediate between those known from twilight-active fireflies and nocturnalactive fireflies.

The New World genus Mycotretus Lacordaire, 1842 (Erotylidae: Erotylinae: Tritomini) is the second most speciose genus within Erotylidae and is found mainly in the Neotropical region. Currently, the genus includes 231 available names, of which 204 are valid. Accurate species identification is hampered by the lack of taxonomic revisions, identification keys or an illustrated catalogue for Mycotretus. To correct this problem and to allow further studies, the objective in this paper is to provide an illustrated catalogue for Mycotretus and propose some taxonomic acts promoting taxonomic stability within the genus. The present catalogue is the result of more than six years of morphological studies and careful comparisons of specimens, including research in several scientific collections throughout America and Europe, searching for identified specimens and types of available names of Mycotretus. The historical literature was examined and all available names listed in the catalogue of Blackwelder (1945) are included here, along with updated information from the catalogue of Alvarenga (1994). Our main results are: (i) examination of types of 216 former available names within Mycotretus, including 74 types previously not examined or not located by Alvarenga (1994); (ii) lectotype designations for 143 available names of Mycotretus; (iii) proposal of 41 new synonyms and three new combinations; (iv) the number of valid species of Mycotretus is reduced from 204 to 174; (v) plates providing images (most of them types) of specimens representing most available names within Mycotretus. The present work is the first major step towards a nomenclatural stability that will allow further revisionary and phylogenetic studies on Mycotretus.
Ten new species of Thinophilus Wahlberg, 1844 from the Afrotropical region are described and illustrated: T. saegeri sp. nov. from the Democratic Republic of the Congo, T. medvedevi sp. nov., T. longicercus sp. nov., T. cataractae sp. nov. and T. manambato sp. nov. from Madagascar, T. gallagheri sp. nov. and T. deemingi sp. nov. from Oman, T. sigwalti sp. nov. from Senegal, T. subpalpatus sp. nov. from South Africa, and T. fluvialis sp. nov. from Tanzania. Type material for 13 previously described Afrotropical species is examined. The genus Paralleloneurum Becker, 1902 is newly synonymized with Thinophilus (syn. nov.). As a result, the following new combinations are here established: Thinophilus cilifemoratus (Becker, 1902) comb. nov. and T. pygmaeus (De Meijere, 1916), comb. nov. The following new synonyms are proposed: Thinophilus annulitarsis Parent, 1936 with T. calopus Loew 1852; T. bipunctatus Curran, 1926 and T. maculatus Parent, 1929 with T. indigenus Becker, 1902. New records are given for some known species. Thinophilus argyropalpis Becker, 1910 and T. spinitarsis Becker, 1907 are reported from the Afrotropical Region for the first time. The number of species of the genus, known from continental Africa, Oman, Yemen and Madagascar, has increased to 30. An identification key to 29 Afrotropical species is compiled. Thinophilus versutus Haliday, 1851 and T. cilifemoratus (Becker, 1902), type species of the former genera Schoenophilus Mik, 1878 and Paralleloneurum Becker, 1902, are subsequently also included into the key, because the two species inhabit northern Africa.
The New World species of the genus Ceratoculicoides Wirth & Ratanaworabhan are described, illustrated and keyed in both sexes. Ceratoculicoides borkenti sp. nov., C. confusus sp. nov., C. grogani sp. nov., C. pacificus sp. nov. and C. propinquus sp. nov. are described, with C. confusus being the first record of the genus from South America (Colombia). Ceratoculicoides blantoni is a junior synonym of C. virginianus and the identity of C. longipennis remains unclear as the male morphospecies associated in taxonomic literature with the female type series is not conspecific. A morphological phylogeny of all extant species in the genus is presented and characters discussed. The moravicus species group is recognized for a clade of species with the lateral margins of the aedeagus straight or concave.
The Cyrtodactylus irregularis group, originally considered to consist of only one taxon, has been split into 26 species. We herein present the distribution of all species within the group in Cambodia, Laos and Vietnam and describe two new species based on integrative analyses. Cyrtodactylus chumuensis sp. nov. is discovered from Dak Lak Province and distinguished from the remaining taxa by more than 11.86% genetic divergence and by the following distinct morphological characters: size medium (SVL 67.5 mm); enlarged femoral scales on each thigh 4–5, femoral pores 0–2 in males; precloacal pores 6–7 in males; ventral scale rows 43–45; lamellae under toe IV 17–21. Cyrtodactylus arndti sp. nov. is described from Binh Dinh Province and genetically differentiated from its congeners by a minimum of 11.42% and by the following characters: adult size medium (SVL 73.4–80.8 mm); enlarged femoral scales on each thigh 5–11; femoral pores 0–2 in males; 6 precloacal pores in males, females with 6 pitted precloacal pores; ventral scale rows 26–38; lamellae under toe IV 17–22; subcaudal scales transversely enlarged. Additionally, we highlight the potential cryptic diversity with the taxon currently regarded as C. pseudoquadrivirgatus and understudied areas in Vietnam where new species will likely be discovered.
Three new species of the bamboo-feeding genus Bambusiphaga Huang & Ding, 1979, B. parvula sp. nov., B. angulosa sp. nov., and B. nigrigena sp. nov., are described and illustrated from China. A key to species of the genus is provided. Habitus photos for adults and illustrations of male genitalia are also given.
The American species of Cosmetidae, in spite of being clearly distinguished in the older literature, were mixed-up by Roewer. This, aggravated by groundless synonymies done by Goodnight & Goodnight, prevented all subsequent authors from properly recognizing and adequately naming those species. Herein, we define and characterize the three most widespread species of Cosmetidae in the USA, explaining the misleading synonymies and misidentifications in the taxonomic literature. A recent phylogenetic analysis revalidated Libitioides Roewer, 1912 from the synonymy of Vonones Simon, 1879 to include three American species: Gonyleptes ornatum Say, 1821 (from southeastern USA), Cynorta sayi Simon, 1879 (from central-southern USA) and Cosmetus albolineatus Sørensen, 1884 (from eastern USA). Expanding on that, we herein aggregate another two species to Libitioides: Vonones modestus Banks, 1909 (from Cuba, herein revalidated from the synonymy of Libitioides ornata Roewer, 1912) and Libitioides scabrissima Roewer, 1912 (from Mexico, restored from the current combination with Vonones). The following subjective synonymies are proposed: (1) Platycynorta Mello-Leitão, 1933 and Denticynorta Roewer, 1947 = Libitioides; (2) Metacynorta denticus Walker, 1928 = Cosmetus albolineatus; (3) Platycynorta secunda Roewer, 1947 = Vonones modestus; (4) Libitioides ornata Roewer, 1912 and Cynorta (Cynorta) depressa Sørensen, 1932 = Cynorta sayi. Outside Libitioides, Cynorta bimaculata Banks, 1893, currently combined under Calicynorta Goodnight & Goodnight, 1943, and originally reported from California (due to a misinterpretation of label) has its type locality corrected as to be in Costa Rica instead and is transferred to Holovonones Roewer, 1912. Accordingly, Calicynorta is herein considered a junior subjective synonym of Holovonones Roewer, 1912. Platycynorta clavifemur Roewer, 1957 from Peru is newly combined under the genus Ambatoiella Mello-Leitão, 1943, otherwise known from Ecuador. The present analysis of the distributional data suggests that the occurrence of Cosmetidae is determined not directly by temperature, but by the absence of a dry season and the presence of a hot summer.
A new species of Laubierpholoe Pettibone, 1992 (Annelida, Sigalionidae), Laubierpholoe massiliana Zhadan sp. nov., was found in two submarine caves near Marseille (France). This is the first record of the genus in the Mediterranean Sea. The new species differs from congeners by inhabiting soft sediments instead of having an interstitial lifestyle and by several morphological characters: the ventral tentacular cirri slightly shorter or of similar length to the dorsal tentacular cirri, the presence of bidentate neurochaetae, the body length, and the number of segments. Molecular phylogenetic analysis using 18S rRNA and 28S rRNA sequences confirmed that the new species belongs to the genus Laubierpholoe, as well as the monophyly of the genus. The ecology of the new species and its adaptation to the cave-dwelling lifestyle are discussed. An identification key for all known species of Laubierpholoe is provided.
Taxonomic history and review of the Förster genera of Platygastridae (Hymenoptera: Platygastroidea)
(2023)
Platygastridae is a ʻdark taxonʼ, with many genera and species in dire need of professional attention. The taxonomic impediment is especially severe in the Palearctic Platygastrinae due to the abundance of names with vague concepts. Historical descriptions and their associated type material must be examined and clarified before further revisionary work can occur. Arnold Förster described 18 genera of Platygastridae, most of which represent distinct and recognizable lineages. The present study reviews their taxonomic history, providing diagnostic remarks, English translations, and illustrations of important specimens from the Förster collection in the Natural History Museum Vienna. The collection also includes original exemplar specimens of European species whose types have been lost. Neotypes and lectotypes are designated from this material to improve nomenclatural stability in the group. Neotypes are designated for Amblyaspis forticornis (Nees, 1834), Isocybus grandis (Nees, 1834), Platygaster striolata Nees, 1834, and Trichacis tristis (Nees, 1834). Lectotypes are designated for Leptacis spinigera (Nees, 1834) comb. nov. and for Platygaster corvina Förster, 1861, with Platygaster henkvlugi Buhl, 1996 treated as a junior synonym. Platygaster mutica Nees, 1834 stat. rev., nomen dubium, is transferred from Synopeas.
Family Corethrellidae has a worldwide distribution with most known extant species occurring in the Neotropics, many with only the adult stages described. Despite previous efforts, one remaining problem in the taxonomy of Corethrellidae is the challenge of delimiting species due to the current range of morphological characters included in descriptions to date. This paper discusses additional morphological evidence to distinguish species and their phylogenetic relationships. Together with fresh samples collected in Bahia, the only state in the Northeast Region with records of corethrellids, and slide-mounted specimens from other regions, five new species are described: Corethrella pindorama sp. nov., C. patasho sp. nov., C. fuscifimbria sp. nov. and C. unifasciata sp. nov. based on female adults; and C. bifida sp. nov. based on male and female adults, and larval and pupal exuviae. We also provide complementary descriptions comprising the novel characters for 33 previously described species, including the immature stages of nine. Fifteen species are newly recorded for Bahia and the Northeast Region, of which two are new records for Brazil. Additionally, we provide remarks about the biology of species, an updated list of species recorded in Brazil and an updated taxonomic key of New World species, modified from Borkent (2008).
Enicospilus Stephens, 1835 is the largest genus of subfamily Ophioninae (Ichneumonidae) with more than 700 extant species worldwide that are mostly nocturnal and parasitoids of larvae of Lepidoptera.

Molluscs are the second most species-rich phylum in the animal kingdom, yet only 11 genomes of this group have been published so far. Here, we present the draft genome sequence of the pulmonate freshwater snail Radix auricularia. Six whole genome shotgun libraries with different layouts were sequenced. The resulting assembly comprises 4,823 scaffolds with a cumulative length of 910 Mb and an overall read coverage of 72×. The assembly contains 94.6% of a metazoan core gene collection, indicating an almost complete coverage of the coding fraction. The discrepancy of ∼690 Mb compared with the estimated genome size of R. auricularia (1.6 Gb) results from a high repeat content of 70% mainly comprising DNA transposons. The annotation of 17,338 protein coding genes was supported by the use of publicly available transcriptome data. This draft will serve as starting point for further genomic and population genetic research in this scientifically important phylum.

Morphological descriptions, photos of body and copulatory organs, as well as the locality map are provided.
Bujurquina is the most widely distributed and species-rich genus of cichlids in the western Amazon of South America. In this study we describe a new species from Peru from a hypothesized reverse flowing river system. Prior to the origin of the modern Amazon River at 4.5 Ma, this river system had its headwaters on the Iquitos arch, one of several main structural arches (swells) in the Amazon. Prior to the origin of the modern Amazon these arches formed topographic barriers of drainage basins in lowland Amazonia. For our analyses we use morphological and molecular data, analyzed through multivariate statistics and molecular phylogenies, respectivelly. For all valid species in the genus (except B. cordemadi and B. pardus) we additionally for the first time provide photographs of live specimens. Based on DNA phylogeny and coloration patterns we demonstrate that Bujurquina is divided into two main clades and based on this we provide a dichotomous key for all the species.
One of the major problems in evolutionary biology is to elucidate the relationships between historical events and the tempo and mode of lineage divergence. The development of relaxed molecular clock models and the increasing availability of DNA sequences resulted in more accurate estimations of taxa divergence times. However, finding the link between competing historical events and divergence is still challenging. Here we investigate assigning constrained-age priors to nodes of interest in a time-calibrated phylogeny as a means of hypothesis comparison. These priors are equivalent to historic scenarios for lineage origin. The hypothesis that best explains the data can be selected by comparing the likelihood values of the competing hypotheses, modelled with different priors. A simulation approach was taken to evaluate the performance of the prior-based method and to compare it with an unconstrained approach. We explored the effect of DNA sequence length and the temporal placement and span of competing hypotheses (i.e. historic scenarios) on selection of the correct hypothesis and the strength of the inference. Competing hypotheses were compared applying a posterior simulation analogue of the Akaike Information Criterion and Bayes factors (obtained after calculation of the marginal likelihood with three estimators: Harmonic Mean, Stepping Stone and Path Sampling). We illustrate the potential application of the prior-based method on an empirical data set to compare competing geological hypotheses explaining the biogeographic patterns in Pleurodeles newts. The correct hypothesis was selected on average 89% times. The best performance was observed with DNA sequence length of 3500-10000 bp. The prior-based method is most reliable when the hypotheses compared are not temporally too close. The strongest inferences were obtained when using the Stepping Stone and Path Sampling estimators. The prior-based approach proved effective in discriminating between competing hypotheses when used on empirical data. The unconstrained analyses performed well but it probably requires additional computational effort. Researchers applying this approach should rely only on inferences with moderate to strong support. The prior-based approach could be applied on biogeographical and phylogeographical studies where robust methods for historical inferences are still lacking.

Campanula cervicaria steht in Hessen kurz vor dem Aussterben und wurde im Rahmen des Kooperationsvertrages zwischen der Botanischen Vereinigung für Naturschutz in Hessen (BVNH) und dem Land Hessen untersucht. Das Ziel der Untersuchung war, herauszufinden wo Campanula cervicaria in Hessen noch vorkommt und wie groß die Populationen sind. In Hessen sind aktuell noch 20 Populationen vorhanden. Fast 90 % der Populationen befinden sich in der Umgebung von Lißberg, Hirzenhain und Gedern im Westlichen Unteren Vogelsberg. Zwei weitere liegen bei Jossa im Spessart und bei Ober-Gleen im Nördlichen Vogelsberg-Vorland. Die größte Population befindet sich an der Kreisstraße 216 bei Hirzenhain am Forsthaus Luisenlust. Campanula cervicaria wächst in Hessen an sonnenexponierten Wegböschungen und Windwurfflächen, meist zusammen mit Hypericum hirsutum und Brachypodium sylvaticum. Um auch zukünftig die Bestände von Campanula cervicaria zu sichern, müsste ein Artenhilfskonzept erarbeitet werden.
Betrachtet man die Anzahl der in Hessen ausgestorbenen Pflanzenarten über den gesamten Zeitraum ab Beginn der floristischen Erforschung, so scheint ein Zusammenhang zwischen der geringeren Anzahl ausgestorbener Arten in den letzten Dekaden und den gleichzeitig vermehrt ausgewiesenen Naturschutzgebieten zu bestehen. Es stellt sich daher die Frage, ob es auch einen kausalen Zusammenhang gibt, oder ob andere Faktoren einen Einfluss auf das Ausmaß an ausgestorbenen Pflanzenarten haben. Für die Entwicklung der Aussterberate in den kommenden Jahrzehnten wird es nötig werden, alle Vorkommen der derzeit vom Aussterben bedrohten Pflanzenarten dahingehend zu überprüfen, ob ihr Bestand gesichert und erhalten werden kann. So kann dann die Frage beantwortet werden, ob es gelungen ist, das Aussterben von Pflanzenarten in Hessen zu stoppen oder lediglich zu verlangsamen.
Im Rahmen des von der KfW Stiftung geförderten Artenschutzprojektes „Erhaltungskulturen von bedrohten Pflanzen in Hessen“ wurden in den Jahren 2014–2018 von 15 gefährdeten Pflanzenarten in verschiedenen Regionen Hessens Samen gesammelt und im Botanischen Garten der Stadt Frankfurt am Main vermehrt. In Zusammenarbeit mit Naturschutzbehörden, Forstämtern und Naturschutzverbänden wurden dokumentierte Wiederansiedlungsmaßnahmen oder Populationsstärkungen durchgeführt. Überzähliges Saatgut wurde im Botanischen Garten eingefroren und kann für zukünftige Artenschutzprojekte verwendet werden. Bei den 15 gefährdeten Arten handelt es sich um Allium strictum, Festuca albensis, Fumana procumbens, Iris spuria, Jurinea cyanoides, Mibora minima, Moenchia erecta, Nigella arvensis, Poa badensis, Scleranthus verticillatus, Sedum villosum, Spergula pentandra, Ventenata dubia, Veronica acinifolia und Vicia orobus. Alle diese Arten sind als Verantwortungsarten Bestandteil der hessischen Biodiversitätsstrategie. Im Jahr 2021, also drei Jahre nach dem Ende des Projektes, ergab eine Erfolgskontrolle folgendes Ergebnis: Von insgesamt 50 Wiederansiedlungsversuchen an 34 Orten sind immerhin 25 (50 %) erfolgreich. Weitere 5 (10 %) sind möglicherweise ebenfalls gelungen, jedoch sind die neu begründeten Populationen sehr klein. Eindeutig misslungen sind 20 (40 %). Die Gründe für das Misslingen sind meist klar erkennbar und werden thematisiert: Manchmal war der Zielort ungünstig gewählt, oder die verwendete Ansiedlungsmethode erwies sich als ungeeignet. Das Projekt konnte dazu beitragen, unser Wissen über Ökologie und Verbreitung sowie Gefährdung und Schutzbedarf dieser Verantwortungsarten teils erheblich zu vermehren. Damit leistet es auch einen Beitrag zum Schutz der bereits bestehenden Altpopulationen.
In diesem Artikel und weiteren geplanten Folgen werden Ergänzungen, Nachträge, Erläuterungen und Korrekturen sowohl zum von der Taunusflora (Wittig & al. 2022) erfassten Gebiet (Vortaunus, Hoher Taunus, kammnaher Hintertaunus) als auch zum bisher nicht bearbeiteten kammfernen Bereich des Hintertaunus publiziert. Bei den bisherigen Ergänzungen und Nachträgen handelt es sich um die Ergebnisse der Nachbestimmung eines Belegs (Allium christophii), den Fund einer für das Gebiet bisher nicht genannten Art (Hylotelephium vulgare) sowie um Hinweise auf ältere Funde (Bolboschoenus maritimus, Polystichum lonchitis) und einen neueren Fund (Luronium natans). Weiterhin werden die wichtigsten Ergebnisse der Begehungen sechs kammferner Rasterfelder präsentiert (Rote-Liste- und sonstige seltene Arten). Als selten werden diejenigen Arten angesehen, die im bisherigen Kartierungsgebiet in maximal 5 % (= 26) der insgesamt 523 Rasterfelder gefunden wurden. Außerdem werden in der Taunusflora enthaltene Fehler korrigiert.
Vergesellschaftung von Salzpflanzen an Straßenrändern unter besonderer Berücksichtigung des Taunus
(2023)
Im Taunus wurden an Straßen bisher fünf Arten festgestellt, die allgemein als Charakterarten der mitteleuropäischen Salzvegetation gelten und daher als Salzpflanzen im engeren Sinne bezeichnet werden können: Cochlearia danica, Plantago coronopus, Puccinellia distans, Spergularia marina und Trifolium fragiferum. Mit Ausnahme der Vorkommen von Trifolium fragiferum handelt es sich dabei oft um nur wenige weitere Arten enthaltende Dominanzbestände, wobei Trittpflanzen am häufigsten vertreten sind, so dass Straßenrandvegetation mit Puccinellia distans in der vorliegenden Literatur allgemein den Trittpflanzengesellschaften zugeordnet wurde (Plantaginetea majoris beziehungsweise Polygono-Poetea annuae). Entsprechendes gilt auch für viele Vorkommen von Plantago coronopus. Wie die vorliegende Arbeit zeigt, können aber einige der aus dem Taunus vorliegenden Aufnahmen mit Plantago coronopus zu den Salzwiesen im weiteren Sinne gestellt werden (Juncetea maritimi). Entsprechendes gilt für die hier präsentierte Vegetationsaufnahme eines Cochlearia-danica-Bestandes. Trifolium fragiferum wurde dagegen in einer als Flutrasen (Molinio-Arrhenatheretea, Agrostietalia stoloniferae) zu bezeichnenden Pflanzengesellschaft angetroffen.
