The Bittacidae fauna in Guizhou Province, China is reviewed. Eleven species in the genera Terrobittacus Tan & Hua, 2009 and Bittacus Latreille, 1805 of Bittacidae are documented in Guizhou, including three new species: Bittacus dilobus sp. nov. and Bittacus leigongshanicus sp. nov. from Leigongshan, and Bittacus multisetus sp. nov. from Yushe. A key to species of Bittacidae in Guizhou is provided.
During a taxonomic study of the species of Croton sect. Adenophylli occurring in Brazil, approximately 140 collections usually identified as Croton echioides, C. rhamnifolius or C. rhamnifolioides caught our attention due to the distinct morphology of vegetative and reproductive organs. After the analysis of these collections, we concluded that they represent a new species, C. sertanejus Sodré & M.J.Silva sp. nov., which was also corroborated by an anatomical study of their leaves. This new species can be differentiated by pseudomonopodial branching, leaves with petioles up to 1.7 cm long, 4–6 subsessile nectary glands and indumentum of sessile trichomes on both surfaces. Detailed descriptions, including details of leaf anatomy, are provided for C. sertanejus sp. nov. and C. echioides, its closely related species. We also formalize the synonymization of C. kalkmannii under C. echioides and re-evaluate the typification of these names, in order to better clarify their taxonomic status.
A key, an annotated checklist with detailed distribution, biological and host information, and color photographic plates are provided for the 91 species of dacine fruit flies (Diptera: Tephritidae: Dacini) known to occur in Oceania. Dacus virgatus Coquillett, previously a synonym of Bactrocera psidii (Froggatt), is instead considered a junior synonym of B. facialis (Coquillett). The species originally described in 1971 as Dacus (Asiadacus) perpusillus Drew, later reassigned as Bactrocera (Sinodacus) perpusilla (Drew) and in recent years as Zeugodacus (Sinodacus) perpusillus (Drew) actually belongs to genus Dacus, and is transferred back to Dacus, but to the subgenus Neodacus, restored combination. The presence of B. redunca (Drew) is recorded for the first time in New Caledonia. New male lure records include isoeugenol and dihydroeugenol for both B. neoxanthodes Drew and Romig and B. quadrisetosa (Bezzi) and zingerone for Dacus taui (Drew and Romig), all in Vanuatu.

A new lichen species Lecaimmeria pakistanica K.Habib, R.Zulfiqar & Khalid sp. nov. is described and illustrated from rocks in the temperate forests of the Himalaya of Azad Jammu and Kashmir, Pakistan. This species is characterized by its yellow-brown to brown thallus having areoles 0.4 to 1.5 mm across, branched and anastomosing paraphyses, a tall hymenium, large ascospores 20–32 × 10–16 μm, and no substance detected by thin layer chromatography. All other species of the genus have ascospore dimensions in the range of 14–22 × 5–14 μm. A phylogenetic analysis is provided based on ITS nrDNA sequences, and supports the separation of the novel species. Photographs and a comparative analysis with related species of Lecaimmeria are provided to confirm the status of the species.
Two new opilionid species from suborder Cyphophthalmi, family Sironidae, Siro franzi Karaman & Raspotnig sp. nov. and Siro ozimeci Karaman sp. nov., from Austria and Croatia respectively, are described and illustrated. Both species show a close relation to two other relict sironid species from the southern and eastern parts of the Alps, Siro valleorum and Siro crassus. All four species are treated here as a monophyletic, alpine group of genus Siro, opposed to the remaining two European sironids, S. rubens and S. carpaticus (palaeoeuropean Siro group). The history of the alpine Siro group parallels the history of a part of the dynamic European archipelago in the Mediterranean Tethys area, which became a part of the Alpine orogeny. Diversification of the alpine Siro group is the result of the orogenic evolution of the Alps, linked to the Austroalpine and South Alpine tectonic units.

Following a review of the circumscription of the genus Cladoceras Bremek. (Rubiaceae) in relation to Tarenna Gaertn., the new species Cladoceras rovumense I.Darbysh., J.E.Burrows & Q.Luke sp. nov. is described from the dry forests of the Rovuma Centre of Plant Endemism (CoE) in southeast Tanzania and northeast Mozambique. This species has previously been known as Tarenna sp. 53, following the revision of African Tarenna by Jérôme Degreef. A comparison to Cladoceras subcapitatum (K.Schum. & K.Krause) Bremek., the only other member of this genus as currently circumscribed, is provided. The new species is assessed as Endangered under the criteria of the IUCN Red List. New records for Mozambique of two further Rovuma CoE endemics are recorded: Celosia patentiloba C.C.Towns. (Amaranthaceae) and Cordia fissistyla Vollesen (Boraginaceae), both of which are globally threatened.

This review considers a fascinating, from a zoogeographical viewpoint, group of closely related species: Melitaea lutko Evans, 1932, M. timandra Coutsis & van Oorschot, 2014, M. mimetica Higgins, 1940 stat. rev. and M. shahvarica sp. nov. It is a taxonomical and geographical review of these species, and data on the biology of M. shahvarica sp. nov. and nominate subspecies of M. timandra are discussed. A new species, M. shahvarica sp. nov. from Shahvar Mt. (Iran), and a new subspecies, M. timandra binaludica subsp. nov. from Kuh-e-Binalud Mts (Iran), are described. The specific structure of the group given in previous publications is critically evaluated. Hypotheses about a possible phylogenesis of the study group are provided.
Eight new Neotropical species of Dexosarcophaga Townsend, 1917 are described, five from Brazil, Dexosarcophaga phoenix sp. nov., Dexosarcophaga jandainae sp. nov., Dexosarcophaga patiuorum sp. nov., Dexosarcophaga petra sp. nov., and Dexosarcophaga sphaera sp. nov., one from Costa Rica, Dexosarcophaga limon sp. nov., one from Ecuador, Dexosarcophaga napo sp. nov., and one from Colombia, Dexosarcophaga pallida sp. nov. Male and female morphology is documented with photographs and illustrations, including details of the male terminalia for all new species and female terminalia of Dexosarcophaga phoenix sp. nov. and Dexosarcophaga sphaera sp. nov. With the addition of these new species, 58 species of Dexosarcophaga are now known, with records from the American continent spanning from the southern United States to northern Argentina.
The present study aims to resolve the taxonomic confusion involving several taxa within Mycetophagidae Leach, 1815, originating from the introduction of the genus Atritomus Reitter, 1877, and then by its subsequent controversial interpretation. A detailed overview of the taxonomic and nomenclatural history of the taxa previously linked to Atritomus is provided. The authors propose the introduction of Stereophilus Biscaccianti, Audisio & Esser gen. nov. for Atritomus filicornis Reitter, 1887, and the restoration of Entoxylon Ancey, 1869 at the genus rank, together with some rectifications regarding the authorship and the date of publication of both Entoxylon and its type species, E. abeillei Ancey, 1869. Moreover, the Ethiopian species Atritomus vicinus Grouvelle, 1908 is herein transferred to the genus Typhaeola Ganglbauer, 1899 based on the examination of the holotype. The following new combinations are proposed: Entoxylon baudii (Seidlitz, 1889) comb. nov. (from Esarcus Reiche, 1864), Entoxylon besucheti (Dajoz, 1964) comb. nov. (from Esarcus subg. Entoxylon), Entoxylon franzi (Dajoz, 1964) comb. nov. (from Esarcus subg. Entoxylon), Entoxylon inexpectatus (Dajoz, 1964) comb. nov. (from Esarcus subg. Entoxylon), Entoxylon martini (Reitter, 1887) comb. nov. (from Esarcus), Stereophilus filicornis (Reitter, 1887) gen. et comb. nov. (from Atritomus), Typhaeola vicina (Grouvelle, 1908) comb. nov. (from Atritomus).
New information is presented for Neotropical Cerambycidae (Coleoptera). Dolichestola vittipennis Breuning, 1948 is synonymized with D. annulicornis Breuning, 1942, and the species is newly recorded from the Brazilian state of São Paulo. Dolichestola densepunctata Breuning, 1942 is newly recorded from Venezuela and Brazil, and the difference between it and D. annulicornis is reported. Mecas skillmani Santos-Silva and Androw, new species, is described from Mexico (Jalisco). Pannychella callicera (Bates, 1881) is illustrated, and notes on the genus and species are provided. Pannychis Thomson, 1864 is considered a genus different from Mecas LeConte, 1852, and notes on the genus and P. sericea Thomson, 1864, new combination, are given; therefore, Mecas has no subgenera. Pannychina Gilmour, 1962 is synonymized with Dylobolus Thomson, 1868, and Pannychina atripennis (Bates, 1885) is synonymized with Dylobolus rotundicollis Thomson, 1868.

The present study examines whether the chaetotaxy of the costal vein in the calyptrate families Fanniidae and Muscidae deserves more attention in phylogenetic and taxonomic contexts. An overview of the macrotrichia and their arrangement on wing vein C is given. Special attention is given to the presence/absence of ventral and dorsal setulae on the costal sectors CS1‒3. This is described as one variable character (A) with nine states (A0‒A8). Specimens of both sexes (when possible) of each species belonging to 4 of a total of 5 fanniid genera and 115 of a total of 179 muscid genus-group taxa were examined and scored for character A. It was found that the presumed ancestral state of character A differs between the two families. It is further shown that the main transformational trend in character A in Muscidae has been bi-directional, leading either to the loss of ventral setulae or the gain of dorsal setulae. The utility of character A in the Fanniidae and Muscidae is many-sided and involves taxa ranging from species to family. It is concluded that character A and other aspects of costal chaetotaxy deserve more attention in morphology-based studies of calyptrate flies.
The discovery of a new species of the genus Canthocamptus, C. waldemarschneideri sp. nov., in northern Siberia prompted a taxonomic analysis of this genus. In this work, on the basis of cladistic analysis, we show that the genus is not monophyletic. Based on differences in the structure of the endopods on the second pair of male swimming legs, fifth legs of males and females, and caudal rami, we conclude that the Canthocamptus mirabilis species group is a separate genus, Kikuchicamptus gen. nov. Additionally, two species are transferred to the genus Attheyella, and one species, Canthocamptus gibba, is synonymized. The subgenera Canthocamptus (Baikalocamptus) and Canthocamptus (Canthocamptus) are also synonymized. The new species, Canthocamptus waldemarschneideri sp. nov., is most closely related to the American Canthocamptus assimilis Kiefer, 1931 and differs from it in the ornamentation of the abdominal somites and the shape of the caudal setae.
Taxonomy of fourteen very little known species of Nodosariinae Ehrenberg, 1838 in Icelandic waters is revised. Knowledge of these species in the North Atlantic relies mainly on studies in the late 19th and early 20th centuries, using large volume samplers. Later studies have emphasized quantitative samples of a few cm3 where the Nodosariinae are very rare. This study analysed 879 dredging samples where Nodosariinae occurred in 492 samples, comprising 7598 specimens of about 415 000 of all picked foraminifera. Ordination analysis of species distributions reflects prominent temperature and salinity differences that exist in the sampling area (753 000 km2) north and south of the Greenland-Scotland Ridge (GSR). Eight species are restricted to southern temperate waters (> 2°C): Dentalina mutabilis (Costa, 1855), Dentalina antarctica Parr, 1950, Dentalina antennula d’Orbigny, 1846, Dentalina filiformis (d’Orbigny, 1826), Grigelis pyrula (d’Orbigny, 1826), Grigelis guttifera (d’Orbigny, 1846) comb. nov., Grigelis semirugosus ? (d’Orbigny, 1846) and Nodosaria subsoluta Cushman, 1923. Four species (Nodosaria haliensis Eiland & Guðmundsson, 2004, Nodosaria incerta Neugeboren, 1856, Dentalina elegans d’Orbigny, 1846 and Dentalina frobisherensis Loeblich & Tappan, 1953) occur mainly north of Iceland. Two species, Dentalina obliqua (Linnaeus, 1758) and Pseudonodosaria subannulata (Cushman, 1923), have wide tolerance ranges for physical variables.
The monotypic ant genus Igaponera gen. nov. is proposed to include its type species I. curiosa (Mackay & Mackay, 2010). Igaponera gen. nov. is described and phylogenetically compared with other ponerine genera based on external morphology. The type species is known from a single gyne originally described in the genus Pachycondyla Smith, 1858. Igaponera curiosa is easily diagnosed by: costate sculpture on head, mesosoma, and petiole; short, robust, triangular mandibles with blunt apex; relatively large eyes set at mid-length on sides of head; lack of stridulitrum; and presence of distinct but relatively small arolia. Putative apomorphies of the new genus are: cuticular flange concealing metapleural gland opening; vertically standing hypostomal tooth with recessed base; stout mandibular shape with blunt apex; absence of stout spine-like setae on meso- and metatibial apices. Our phylogenetic results based on morphology suggest that Neoponera Emery, 1901 and Pachycondyla are the closest lineages to Igaponera, which shows intermediate characteristics as compared to those genera. The genus is apparently arboreal, known only from a seasonally flooded Igapó forest near Manaus, Brazil. Despite the collection site being frequented by researchers, no other specimens of this genus have been collected in over 40 years prior to this study.
Psychodid specimens from one of the world’s biodiversity hotspots – the Caucasus region – were sorted from samples collected during field work in 2019. Pneumia fuehzulii sp. nov. (from two localities in Azerbaijan) and Thornburghiella salihi sp. nov. (from one locality in Azerbaijan and four sites in Georgia) are described from this material. Differential diagnoses are given and some morphological characters illustrated. Sijaricia Krek, 1999, syn. nov. of Thornburghiella Vaillant, 1982 is proposed and T. erinacea (Krek, 1971) comb. nov. from Ulomyia Walker, 1856 is suggested.
The ammonoids of the suborder Gephuroceratina from the Roteisenstein (Red Ironstone) Formation of the area around Dillenburg (eastern Rhenish Mountains) are revised, mainly based on historical collections stored in the Museum für Naturkunde, Berlin. The new species Ponticeras materni sp. nov. is described and the species Pseudoprobeloceras pernai (Wedekind, 1918), Pseudoprobeloceras applanatum (Wedekind, 1918), Ponticeras aequabile (Beyrich, 1837), Darkaoceras galeatum (Matern, 1931), Taouzites acutus (Matern, 1931), Koenenites lamellosus (Sandberger & Sandberger, 1851), Acanthoclymenia forcipifera (Sandberger & Sandberger, 1851) and Acanthoclymenia planorbis (Sandberger & Sandberger, 1851) are revised. The stratigraphic distribution of the genera is discussed; they are assigned to three assemblages: (1) Pseudoprobeloceras pernai Zone (latest Givetian; genera Pseudoprobeloceras, Ponticeras, Darkaoceras and Taouzites), (2) Koenenites lamellosus Zone (early Frasnian, containing Koenenites lamellosus and Acanthoclymenia forcipifera) and (3) Mesobeloceras kayseri Zone (middle Frasnian, containing Acanthoclymenia planorbis).
Two new species of the family Nemouridae of the genus Indonemoura Baumann, 1975, Indonemoura yingjiangensis Bai & Qian sp. nov. and Indonemoura longihamata Bai & Qian sp. nov. are described from Yunnan Province, southwest of China. The morphological characteristics of the two new species are compared to related taxa.
The kinorhynch fauna from Portugal has been explored, yielding a new species of the genus Setaphyes (Kinorhyncha: Allomalorhagida). This is the first description of an allomalorhagid species from Portugal. Specimens of the new species were collected at a subtidal muddy beach in Alvor, a village located in the southernmost region of Portugal. Setaphyes algarvensis sp. nov. may be distinguished from its congeners by a unique arrangement of the setae: paired paradorsal setae on segments 2–7 and 9, paradorsal seta on segment 8 unpaired, laterodorsal setae on segments 2–3 and 6–9 in males and 2–9 in females, paralateral setae on segment 1, lateroventral setae on segments 2–10 (two pairs on segment 5), ventrolateral setae on segment 1 in males and 1–3 in females, and ventromedial setae on segments 3–9 in males and 4–9 in females. The diagnostic features of Setaphyes algarvensis sp. nov. are discussed from a comparative perspective with the congener species. Additionally, morphometric analyses of selected features, namely the total trunk length and the relation between the total trunk length and the length of lateral terminal spines, turned out to be useful to distinguish between the new species and Setaphyes kielensis (its most similar congener).
A revision of microscope slides deposited between 2014 and 2017 in the collection of Rocha and Doma (National University of La Pampa, Argentina) revealed three new species of the genus Milnesium Doyère, 1840: M. pelufforum sp. nov., M. irenae sp. nov. and M. quiranae sp. nov. Milnesium pelufforum sp. nov. is mostly characterized by ten transverse bands of sculptured cuticle and pseudoplates (the first band, until now, never detected in the genus), six peribuccal lamellae and claw configuration [2-2]-[2-2] in young or [2-3]-[3-2] in senior specimens. Milnesium irenae sp. nov. is mostly characterized by complex cuticular ornamentation including a fine reticulation different from the typical one in the genus; it also has pseudoplates, six peribuccal lamellae, medioventral peribuccal papilla reduced, stylets, their furcae and supports very developed, and claw configuration [2-3]-[2-2]. Milnesium quiranae sp. nov. is mostly characterized by smooth cuticle, six peribuccal lamellae, and claw configuration [3-3]-[3-3]; with growing, the medioventral peribuccal papilla reduces and the buccal tube becomes wider. With the present contribution the genus Milnesium now has 48 valid species, and the number of described limno-terrestrial tardigrade species from South America has risen to 11, including 8 from Argentina with 5 from Salta and La Pampa province.
The pseudoscorpion (Arachnida: Pseudoscorpiones) fauna of mainland Ecuador, excluding the Galápagos Islands, is poorly known, with only 41 described species in 9 families. The family Syarinidae has a pantropical distribution and presently comprises ca 120 species in 17 valid genera that are found in leaf litter and subterranean habitats, mostly in tropical and subtropical climates. Four syarinid species have been recorded from Ecuador, including the Galápagos, in two widespread genera, Ideobisium and Ideoblothrus, but field collections suggest that these pseudoscorpions are common and abundant in all forest systems across the country. Here, we review field collections of syarinids from mainland Ecuador and describe five new species in these genera: Ideobisium kichwa sp. nov. (Napo Province, Colonso Chalupas Natural Reserve), I. sonqo sp. nov. (Napo Province, Colonso Chalupas Natural Reserve), I. susanae sp. nov. (Napo Province, Jatun Sacha Natural Reserve), Ideoblothrus nadineae sp. nov. (Napo Province, Colonso Chalupas Natural Reserve) and I. safinai sp. nov. (Pichincha Province, Otongachi Natural Reserve) based on morphology. These species seem to have narrow distributions and we therefore restrict the ranges of two species previously recorded from Ecuador (Ideobisium crassimanum Balzan, 1892 and Ideoblothrus costaricensis (Beier, 1931)) to their countries of origin, which is Costa Rica and Venezuela, respectively.
Here, we present the results of our field survey in Sri Lanka and describe ten new species of Sericini: Selaserica fabriziae sp. nov., Sel. sororinitida sp. nov., Neoserica pophami sp. nov., Maladera haniel sp. nov., M. kishi sp. nov., M. windy sp. nov., M. karunaratnae sp. nov., M. hiyarensis sp. nov., M. dambullana sp. nov., and M. deenstana sp. nov. All seven of the newly described species of Maladera belong to the M. fistulosa species group, which is an endemic radiation on the island that is characterized by entirely reduced or fused parameres. An updated key to the Maladera fistulosa group is provided. Further, new locality records for 23 already known species are given. The genitalia and habitus of all new species are illustrated, the distribution of the new species is shown with maps.
Benthic samples collected along the Brazilian central continental margin from Espírito Santo State to Rio de Janeiro State (19° S to 24° S) during the last 20 years and at depths of 50–2200 m yielded the description of six new species of Typhlotanais in the deep-sea (> 200 m): Typhlotanais andradeorum sp. nov., T. bolarticulus sp. nov., T. ischnochela sp. nov., T. longiseta sp. nov., T. priscilae sp. nov. and T. spinibasis sp. nov. Within these species, we found members of four Typhlotanais morpho-groups as ‘cornutus’ group, ‘greenwichensis’ group, ‘spinicauda’ and ‘trispinosus’ group. Typhlotanais ischnochela sp. nov. exhibited the greatest bathymetric range, occurring from the continental shelf until the lower slope (46–1898.7 m depth). The bathymetric distribution of the other five species of Typhlotanais herein described were restricted to the slope. Tables of diagnostic characters of the Typhlotanais morpho-groups and an identification key to the species of Typhlotanaidae found in Brazil are provided. This work brings the total number of Tanaidacea known for Brazilian coast to 64 species, and the family Typhlotanaidae from Brazil is now represented by 11 species in five known genera.
Revision of the Eurasian species of Aegilips Haliday, 1835 (Hymenoptera: Figitidae: Anacharitinae)
(2022)
The knowledge of Aegilips in Eurasia is updated. One new species is described: Aegilips insularis Mata-Casanova and Pujade-Villar sp. nov., from Portugal (Madeira). The genus is also cited for the first time in the Indomalayan region with specimens of A. atricornis found in Northern India and Pakistan. Aegilips curvipes Giraud, 1860, Aegilips gemellus Belizin, 1961, Aegilips laevis (Hedicke, 1914), Aegilips montanus Belizin, 1951 and Aegilips punctatus Belizin, 1951 are synonymized with A. nitidulus (Dalman, 1823). Aegilips vena Fergusson, 1985 is synonymized with Aegilips zaitzevi Kovalev, 1974. Aegilips notatus Belizin, 1951, and Aegilips punctulatus Hedicke, 1928 are designated as incertae sedis. The known distributions of A. atricornis, A. kozlovi, A. nitidulus and A. romseyensis are expanded. Morphological differences are discussed and a key for Eurasian Aegilips species is also given.

A new species of the genus Caucaseuma Strasser, 1970, Caucaseuma strasseri Antić sp. nov., is described from a cave in the Western Caucasus, representing the eighth species of the genus, and the fourth presumed troglobiontic Caucaseuma. An updated key to and a distribution map of all eight species of Caucaseuma is presented, including new records. In addition, the cave millipede fauna of the Caucasus is briefly discussed, with the inclusion of the most relevant references.
Acrostilicus Hubbard, 1896 and Pachystilicus Casey, 1905 are North American genera known from only one and two species, respectively, and have never been a subject of a modern revision. In fact, Acrostilicus was not even properly described as its author provided only a sketchy diagnosis of the genus and species. Here, we provide a redescription of the genus Acrostilicus and its species and illustrate the habitus and male genital features. For the first time, we also redescribe Pachystilicus and its two species, and provide their differential diagnoses. Additionally, we tested the phylogenetic position of both genera. They were scored into a morphological matrix supplemented with molecular data and the analyses were run using Bayesian inference and maximum likelihood methods. A total of 119 morphological characters and 4859 bp of nuclear (28S, TP, Wg, CADA, CADC, ArgK) and mitochondrial (COI) sequences were analysed for 46 taxa. The results confirmed that both Acrostilicus and Pachystilicus are members of the subtribe Stilicina, but at the same time challenged the monophyly of the subtribe in its current composition. Additionally, we provided further evidence for non-monophyly of the subtribe Medonina and discussed the biology of Acrostilicus and Pachystilicus.
Japanese species of the genus Georissus are revised. Seven species, including two new, G. (Neogeorissus) takahashii sp. nov. and G. (Ne.) satoi sp. nov. are recognized. Georissus (Neogeorissus) sakaii Satô, 1972 and G. (Ne.) katsuoi Nakane, 1995 are synonymized with G. (Ne.) japonicus Satô, 1972. Based on the type series and additional specimens, three subgenera and seven species are (re)described with SEM micrographs of the external morphology and figures of male and female genitalia. The terminology of some structures of the head and the pronotum are redefined for convenience of taxonomy. A key to the Japanese species is also given.
The hoverfly genus Eumerus Meigen, 1822 (Eristalinae: Merodontini) comprises 250+ described species, of which 36 are reported from the Iberian Peninsula. The high species diversity linked to the low degree of morphological differentiation between some species, which is even lower in females, leads to a high taxonomic complexity in this genus. The aim of this work is to confirm the morphological and molecular validity of an undescribed species of Eumerus, which is widespread in the Iberian Peninsula. The new species is described and compared with similar species. The genitalia of the new species are similar to those of Eumerus clavatus Becker, 1923 and Eumerus uncipes Rondani, 1850, but also share some features with Eumerus nudus Loew, 1848. The COI-5’ barcode is provided for the new taxon and analysed together with those of other named Eumerus sequences/species publicly available online. In the light of the morphology and barcoding data, the systematic position of the new species is discussed.
The previously endemic Australian genus Habritella Girault & Dodd, 1915 is reported for the first time in the Afrotropical region with four new species: H. africana sp. nov., H. mandibulata sp. nov., H. noyesi sp. nov., and H. viridifrons sp. nov. The males of Habritella are described for the first time. A new generic synonymy and combination are also proposed: Ezgia Koçak & Kemal, 2008 syn. nov. and H. stylifera (Bouček, 1988) comb. nov. Habritella is redescribed to accommodate the newly discovered and transferred species. An illustrated key to the Afrotropical species is provided.
The finding of Breviconia andrei sp. nov. in the Russian Bering Sea enabled the clear-cut phylogenetic characterization of the former monotypic genus Breviconia Conroy-Dalton & Huys, 2000 as a monophylum. Comparison of the new species with B. australis (George, 1998) and other members of the subfamily Ancorabolinae Sars, 1909 yielded four autapomorphies that unambiguously support the monophyletic state of Breviconia: (1) an elongated and approximately 90°-curved mandibular gnathobase, (2) reduction of the maxillar endopod, (3) maxillar endites carrying 2 instead of 3 setae, and (4) loss of the minute seta on the maxillipedal claw. For B. andrei sp. nov., two autapomorphies could be detected, namely, (1) the development of dorsal tubercles on the P5-bearing body somite and (2) the remarkable elongation of the first endopodal segment of the first swimming leg that is twice as long as the whole exopod. Of particular interest is the presence of a 3-segmented endopod in the third swimming leg of the male of B. andrei sp. nov. It disproves the current assumption that the Ancorabolinae are characterized by (among others) the derived presence of an only 2-segmented endopod in the male’s third swimming leg.
Three new six-eyed species of the spider genus Caponina Simon, 1891 are described, photographed, diagnosed and illustrated: C. alejandroi sp. nov. (male and female) from the Boyacá Department, C. bochalema sp. nov. (male) from the Santander Department and C. huila sp. nov. (male) from the Huila Department. Also, a emended diagnosis for the genus, a distribution map and an identification key for all species of Caponina are provided.
A global synonymical checklist of the species and higher taxa of the insect order Megaloptera is provided. The checklist includes both extant and extinct taxa, and recognizes 2 families, 4 subfamilies, 48 genera, 425 species, and 6 subspecies. Both families (Corydalidae and Sialidae), and three of the four subfamilies (Corydalinae, Chauliodinae, and Sialinae) are known from both extant and extinct species; the Sharasialinae (Sialidae) is entirely extinct. Country-level geographic distribution data are provided for all species and subspecies. Synoptic type data are provided for taxa in the family and genus groups. Summary data are given for the numbers of megalopteran species currently known to occur in each of the major biogeographical regions of the world, and for the world fauna. Increase of knowledge about the diversity of the world Megaloptera fauna is summarized in counts of valid species described per decade and in a global taxonomic description curve. An updated set of keys to the world families, subfamilies, and genera of the Megaloptera is also provided.
A new species of the Neotropical genus Platygonia Melichar, 1925 is described and illustrated from the municipality of Ipixuna, State of Amazonas, Northern Brazil. Platygonia nigra sp. nov. can be distinguished from the other species of the genus by the following combination of features: (1) dark brown to black ground color of dorsum; (2) presence of a white to pale yellow spot at the distal portion of corium; (3) male pygofer with a conspicuous diagonal cleft; (4) connective Y-shaped, keeled, with the stem longer than the arms; and (5) aedeagus with an unpaired basiventral process directed anteriorly. This is the first record of the genus from the Brazilian Amazon Rainforest. Notes on P. undecimmaculata (Fowler, 1899), which is a taxon of uncertain taxonomic position, a key to the species of Platygonia, and a map showing their distribution are added.
Two new species of Psyllocarpus sect. Psyllocarpus, P. itakangapyra Sobrado, J.A.M.Carmo & R.M.Salas sp. nov. and P. vianae Sobrado, J.A.M.Carmo & R.M.Salas sp. nov., from the “campo rupestre” of the state of Minas Gerais, southeastern Brazil, are here described and illustrated. We provide comments on their distribution, habitat, and preliminary conservation status, and discuss their taxonomy. In addition, we analyse floral, fruit, and seed micromorphology, as well as pollen grains of the new species. We also provide an updated identification key to the species of P. sect. Psyllocarpus.
