Two subspecies of Cosmodela duponti (Dejean) (Coleoptera: Cicindelidae) are elevated to species rank: Cosmodela barmanica (Gestro) and C. indica (Fleutiaux). The lectotypes of all the above-mentioned species are designated as well. Short redescriptions of the three species are provided together with a key, and illustrations of their habitus.
Thirty-four species of dacine fruit flies (Diptera: Tephritidae) were recorded in Bangladesh, based on field surveys carried out between 2013 and 2020. Five species are reported in Bangladesh for the first time: Bactrocera aethriobasis (Hardy), B. limbifera (Bezzi), B. melania (Hardy and Adachi), B. nigrifemorata Li and Wang, and Dacus jacobi David and Sachin. The attraction of B. nigrifemorata to cue-lure is a new male lure association. An annotated checklist and illustrated key to the species are provided.
The Nearctic species of Nematodes Berthold (Coleoptera: Eucnemidae: Macraulacinae: Nemato-dini) are reviewed. Four species are redescribed. One new species, Nematodes rugosipennis Otto (Coleoptera: Eucnemidae) is described from Florida, Georgia, and Oklahoma, USA. A key to species modified from Muona (2000) is provided for all known species of Nematodes present in the Nearctic region.
Hamaticherus Dejean, 1821 (Coleoptera: Cerambycidae: Cerambycinae) is considered a junior synonym of Cerambyx Linnaeus, 1758. Hamaticherus sensu Audinet-Serville, 1834 is considered a posterior usage of Hamaticherus Dejean, 1821, and an unavailable name. Plocaederus is considered as a new genus, and not a replacement name, proposed by Dejean (1835) to allocate the species included in Hamaticherus sensu Audinet-Serville, 1834. Therefore, a new genus, Hamaederus Santos-Silva, Garcia and Botero,is herein proposed to include the species currently allocated in Plocaederus Dejean, 1835, creating 15 new combinations, and additionally, a new species from French Guiana, Hamaederus allofasciatus Santos-Silva, Garcia and Botero, is described. Furthermore, Plocaederus barauna Martins and Monné, 2002 and Plocaederus confusus Martins and Monné,2002 are proposed as new junior synonyms of Hamaederus yucatecus (Chemsak and Noguera, 1997), and Hamaticherus bellator Audinet-Serville, 1834 is transferred to Plocaederus Dejean,
1835, new combination. New geographical records are provided for Hamaederus fraterculus (Martins), H. glaberrimus (Martins), H. rusticus (Gounelle), and H. yucatecus (Chemsak and Noguera). Hamaederus fasciatus is formally excluded from the fauna of French Guiana. A key to American genera of Cerambycina (Cerambycini) is provided.
Fractipes tayrona new species (Coleoptera: Chrysomelidae: Eumolpinae: Eumolpini) is described from a dry forest on the Caribbean coast of Colombia. This locality is very distant from the localities in southeast Brazil, where the other two known species of Fractipes Bechynĕ were described. Male and female genitalia are described for the first time in this genus, and F. tayrona is compared with holotype photographs of F. rhabdopteroides Bechynĕ and F. secundus Bechynĕ and Springlová de Bechynĕ.
Allomyia renoa (Milne, 1935) (Trichoptera: Apataniidae) was described from six females. The male association is verified in this paper. The original type locality information is limited: “Reno, Nev.,‘78, Morrison”. An Allomyia Banks population found at Mount Rose in Washoe County, Nevada, was compared to the A. renoa type material and found to be the conspecific. Figures, descriptions and distribution of male, female, pupal and larval A. renoa are provided.
A recent phylogenetic analysis has shown that the genus Stephanopis comprises several different lineages of bark-dweller crab spiders. The ones with South American distribution that present a close relationship with other Neotropical genera like Epicadus, Onocolus, Rejanellus and Epicadinus were recovered in a single clade, with good support and stability. Here, we present a taxonomic review of Stephanopis species attributed to the ‘pentacantha clade’, proposing the new genus Kryptochroma Machado gen. nov. to accommodate them. New distribution records are provided and the following species are described for the first time: Kryptochroma gigas Machado & Viecelli gen. et sp. nov., Kryptochroma hilaris Machado & Teixeira gen. et sp. nov., Kryptochroma quadrata Machado & Viecelli sp. nov. and Kryptochroma septata Machado & Teixeira sp. nov. The species Stephanopis borgmeyeri is considered a nomen dubium, Stephanopis aheneus is a junior synonym of Epicadus tuberculatus, Stephanopis quimiliensis is transferred to Ulocymus and Stephanopis stelloides is transferred to Epicadus, being Epicadus stelloides the senior synonym of Stephanopis salobrensis, Stephanopis trilobata and Epicadus caudatus.
The Chinese species of the genus Chinoperla Zwick, 1980 are reviewed. One species from Hainan is described as new to science: C. changjiangensis sp. nov. Chinoperla gorohovi Sivec & Stark, 2010 is reported from China for the first time, with a redescripion and color images of the male, and the first description of the female and egg. Chinoperla nigrifrons (Banks, 1939) is redescribed and illustrated, synonymy of C. furcomacula (Wu, 1973) is confirmed. Taxonomic relationships within the studied species are discussed. A provisional key to the six known species of Chinoperla for China is presented.
A new Brazilian leafhopper genus of the subfamily Neocoelidiinae is proposed: Takiyaella gen. nov. based on T. sexguttata (Chiamolera & Cavichioli, 2003) gen. et comb. nov. and five new species: T. anomala gen. et sp. nov., T. coelhomarquesae gen. et sp. nov., and T. daniela gen. et sp. nov. from the state of Rio de Janeiro; T. cavichiolii gen. et sp. nov. from the state of Paraná, and T. mejdalanii gen. et sp. nov. from the state of Minas Gerais. A distribution map and identification key to Takiyaella species are provided.
Two novel species of Russula (Russulaceae, Russulales), R. coronaspora Y.Song sp. nov. and R. minor Y.Song sp. nov. belonging to subgenus Russula crown clade, are described based on both morphological and phylogenetic evidence. In morphology, R. coronaspora sp. nov. is mainly characterized by its distinct spores ornamented with sparse, cylindrical and isolated spines, which resemble coronavirus, and gelatinized pileipellis with pileocystidia mostly septate and sometimes branched; R. minor sp. nov. possesses a very small basidiocarp with pileus less than 2.5 cm in diameter., small basidia, easily peeling and gelatinized pileipellis with slender terminal cells and abundant SV+ pileocystidia. Positions of the two new species in both phylogenetic trees based on ITS and 5-locus sequences (nLSU, mtSSU, rpb1, rpb2 and tef1) confirm their distinct taxonomic status.
A comprehensive survey of several lakes in the Tuva Republic of Russia yielded, besides the ubiquitous Gammarus lacustris, the discovery of a small freshwater, lacustrine amphipod not previously recorded in this area. A comparative study of the Tore-Khol Lake gammarid population, probably conspecific with Gammarus koshovi (Bazikalova, 1946) originating from Khubsugul Lake, was conducted. The species, G. koshovi, is characterized by a specific habitus: a small-sized compact body, all limbs shortened, carpi of pereopods (PIII and PIV) reduced, coxal plates broad, and pereopod dactyli sturdy. It has been suggested that juveniles of the euryoecious G. lacustris or other large species could be confused with the relatively small G. koshovi. Consequently, we decided to present the distribution of gammarid species throughout south Siberia and Mongolia, referring to the sequences of works primarily by Soviet authors, which may be hard to access by international readers. We discuss affinity with related groups, distribution, and ecology of G. koshovi to better understand their evolution. Additionally, the zoobenthic species diversity of widely represented groups in the ecosystems of Tore-Khol Lake is briefly reviewed. An identification key for the Siberian Gammarus with 10 species is provided.
Four new Colombian species of the spider genus Medionops Sánchez-Ruiz & Brescovit, 2017 are described and illustrated: M. carolinae sp. nov. (male and female) from Boyacá department, M. cauca sp. nov. (male) from Cauca department, M. luiscarlosi sp. nov. (male and female) from Caldas department and M. santarosa sp. nov. (male) from Risaralda department. Additionally, the distribution of the type species of M. blades Sánchez-Ruiz & Brescovit, 2017, previously known only from Bogotá, Cundinamarca department, is extended to several localities in the Boyacá department. An updated identification key for all Medionops species is provided.
The taxonomy of cyclostome bryozoans is founded on characters of the skeleton, but molecular sequence data have increasingly shown that established higher taxa are not monophyletic. Here we describe the skeletal morphology of a new species from Guadeloupe (French West Indies) with erect ramose colonies consisting of long, curved zooids that are typical of the suborder Cerioporina among living cyclostomes. However, molecular evidence from nuclear ribosomal RNA genes 18S and 28S places the new taxon in the suborder Rectangulata, where this colony-form has not been previously recorded. It nests firmly within the genus Disporella Gray, 1848, in a strongly supported clade that also includes Plagioecia patina (Lamarck, 1816) (Tubuliporina) and the sister taxa Doliocoitis cyanea Gordon & Taylor, 2001 (Rectangulata) and Favosipora rosea Gordon & Taylor, 2001 (Cerioporina). The short and robust branches of the new Guadeloupe cyclostome, here named Disporella guada Harmelin, Taylor & Waeschenbach sp. nov., are well adapted to life in shallow rocky sites exposed to severe wave action, which appear to be its exclusive habitat.
The whip spider family Charinidae Quintero, 1986 is the most speciose and widely distributed in the arachnid order Amblypygi Thorell, 1883. It comprises three genera and 95 species distributed across all tropical continents and the eastern Mediterranean. Despite recent advances in the taxonomy of the family, a global revision of all its species, necessary to advance understanding of its systematics, biogeography and evolution, has never been conducted. In the present contribution, the family is revised in its entirety for the first time, including all previous names and 33 new species, 24 in the genus Charinus Simon, 1892: C. alagoanus sp. nov., C. apiaca sp. nov., C. carinae sp. nov., C. carioca sp. nov., C. carvalhoi sp. nov., C. cearensis sp. nov., C. diamantinus sp. nov., C. euclidesi sp. nov., C. goitaca sp. nov., C. guayaquil sp. nov., C. imperialis sp. nov., C. loko sp. nov., C. magalhaesi sp. nov., C. miskito sp. nov., C. mocoa sp. nov., C. monasticus sp. nov., C. palikur sp. nov., C. perquerens sp. nov., C. puri sp. nov., C. renneri sp. nov., C. sooretama sp. nov., C. souzai sp. nov., C. susuwa sp. nov., C. una sp. nov.; eight in the genus Sarax Simon, 1892: S. bilua sp. nov., S. dunni sp. nov., S. gravelyi sp. nov., S. indochinensis sp. nov., S. lembeh sp. nov., S. palau sp. nov., S. rahmadii sp. nov., S. tiomanensis sp. nov.; and one in the genus Weygoldtia Miranda et al., 2018: W. consonensis sp. nov. Taxonomic keys to the 132 species (excluding four nomina dubia) are presented and several taxonomic rearrangements implemented. Four subspecies are elevated to species level: Charinus cavernicolus Weygoldt, 2006, C. elegans Weygoldt, 2006, C. longipes Weygoldt, 2006, and Sarax bispinosus (Nair, 1934). Sarax batuensis Roewer, 1962 is removed from synonymy with Sarax buxtoni (Gravely, 1915) and S. buxtoni newly synonymized with Sarax rimosus (Simon, 1901). Stygophrynus moultoni Gravely, 1915 is transferred to Sarax, resulting in Sarax moultoni (Gravely, 1915) comb. nov. Ten species are transferred from Charinus to Sarax, resulting in new combinations: S. abbatei (Delle Cave, 1986) comb. nov., S. bengalensis (Gravely, 1911) comb. nov., S. dhofarensis (Weygoldt, Pohl & Polak, 2002) comb. nov., S. ioanniticus (Kritscher, 1959) comb. nov., S. israelensis (Miranda et al., 2016) comb. nov., S. omanensis (Delle Cave, Gardner & Weygoldt, 2009) comb. nov., S. pakistanus (Weygoldt, 2005) comb. nov., S. seychellarum (Kraepelin, 1898) comb. nov., S. socotranus (Weygoldt, Pohl & Polak, 2002) comb. nov. and S. stygochthobius (Weygoldt & Van Damme, 2004) comb. nov.
The pharciceratid ammonoids from the Roteisenstein Formation of Dillenburg (Cephalopoda, Ammonoidea)
(2021)
The ammonoids of the suborder Pharciceratina from the 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 genus Evopharciceras gen. nov. and the following species are newly described: Maenioceras ornatum sp. nov., Pharciceras beyrichi sp. nov., Pharciceras kruegeri sp. nov., Pharciceras ferrum sp. nov., Evopharciceras formosum gen. et sp. nov., Extropharciceras metallicum sp. nov., Lunupharciceras kochi sp. nov., Stenopharciceras lotzi sp. nov., Pluripharciceras ahlburgi sp. nov. and Sandbergeroceras archiaci sp. nov. Neotypes are proposed for the species Extropharciceras becheri (von Buch, 1832) and Sandbergeroceras costatum (d’Archiac & de Verneuil, 1842). The stratigraphic distribution of the genera is discussed; they are assigned to three assemblages: (1) Maenioceras terebratum Zone (early Givetian; two species), (2) Pseudoprobeloceras pernai Zone (latest Givetian; fifteen species) and (3) Sandbergeroceras costatum Zone (early Frasnian; three species).
For each of the 534 species of the millipede order Chordeumatida known from Europe, available information on taxonomy, distribution and habitat is summarized, and the distribution in 50 × 50 km UTM/MGRS squares is shown on a map. Comparisons between Chordeumatida and the equally-sized order Julida are made with respect to distribution patterns and history of exploration.
Grasstrees (Xanthorrhoea) are a group of monocotyledonous plants endemic to Australia, with a characteristic crown of long and narrow leaves. In the present study, the grasstree-associated weevils of the genus Paratranes Zimmerman, 1994 are reviewed and two species are recognised: P. monopticus (Pascoe, 1870) and P. zimmermani sp. nov. A lectotype for Tranes xanthorrhoeae Lea, 1898, which was recently synonymised with P. monopticus, is herein designated, and the validity of this synonymy is confirmed. Descriptions and diagnoses of the species are supplemented with photographs of their habitus and salient structures as well as a map of their distributions.
Two new species of the genus Eponisiella Emeljanov, 1984 are described and illustrated from China (Guizhou and Shandong Provinces). These are E. dafangensis sp. nov. and E. shandongensis sp. nov., giving the genus eight species in total. A key to the species of Eponisiella is provided as well as a map of their geographic distribution, which is briefly discussed.
Ophiuroidea is the largest class among extant echinoderms, with over 2000 described species assigned to 33 families. Here, the first identification key to the recently revised classification was developed, and revised morphological descriptions were derived from it, expanding the previous short diagnoses. The key was built by analyzing internal and external skeletal characters of predominantly the type species of each family, including at least two mutually exclusive attributes per family. Various numeric and multistate characters were used to create a traditional as well as an interactive key using the DELTA and Xper software programs. Illustrations (SEM and digital photos) are included in the key to facilitate the assessment of character states by users. Not only is it the first identification key to the families, according to the recently proposed new classification and the examined species, but this interactive key also assists users in understanding the family level taxonomy of brittle stars. The interactive key allows new characters and states to be added, when more species will have been analyzed, without the need to reconfigure the complete key (as may be necessary with conventional keys).
In an elevational gradient, the mountain top generally presents a reduced species diversity. However, it is there where we often find microendemic and quite often still undescribed species. That prediction is very common in underexplored Neotropical mountains, like those of the Caparaó National Park – a protected area that includes the highest peak of the Atlantic Forest, a megadiverse domain. Up in its top, we found a dwarf frog of the genus Physalaemus (Anura, Leptodactylidae, Leiuperinae), belonging to the P. signifer clade. After an integrative (morphological, bioacoustical, and genetic) analysis, we were able to describe it as a new species and found it to be sister to P. maculiventris. Due to its very restricted distribution at a site with extreme environmental conditions (which includes fires and frosts) and current instability in national environmental policy, we suggest this to be classified as an endangered species. A brief description of its natural history and the description of the species itself will now enable its proper conservation status categorization and the future planning for conservation actions.
The genus Oplognathus MacLeay, 1819 is revised based on type material of two of the three described species and scattered additional material from several collections around the world. The diagnostic characters of the genus are confirmed, distinguishing it from other Brazilian Areodina mainly by: quadrangular clypeus with trilobate apex in males, rounded in females, extending beyond labrum in both sexes; mandibles with three distinct teeth; maxillae with six teeth; antenna with 10 antennomeres; 10 elytral striae; mesoventral process present; and asymmetrical parameres. The genus and all three species are redescribed, and the female of Oplognathus bahianus Ohaus, 1912 is described for the first time. We consider Oplognathus helmenreichi var. maculicollis Ohaus, 1914 an unavailable infrasubspecific taxon that is conspecific with Oplognathus helmenreichi Ohaus, 1905; its distribution is updated, and the different spelling of the specific epithet is discussed. A neotype is designated for Oplognathus kirbii MacLeay, 1819 since the holotype is currently considered lost. Additionally, an identification key and a distribution map are included.
An ongoing study of the longhorned beetle fauna in the cloud forests of Cusuco National Park revealed multiple additions to the Honduran fauna. Four new species are described: Heterachthes caceresae sp. nov. (Cerambycinae, Neoibidionini), Oreodera kawasae sp. nov. (Lamiinae, Acrocinini), Phrynidius guifarroi sp. nov. (Lamiinae, Apomecynini), and Strangalia lunai sp. nov. (Lepturinae, Lepturini). Additionally, Lagocheirus parvulus Casey, 1913 (Lamiinae, Acanthocinini) is revalidated as Lagocheirus araneiformis parvulus Casey, 1913 (Lagochirus [sic]). We recorded Arixiuna varians (Bates, 1881) (Lamiinae, Hemilophini) for the first time for Honduras. These findings confirm how poorly the invertebrate biodiversity of cloud forests is documented and hints at the large number of species we are losing with the ongoing deforestation.
The genus Trypheridium Brancucci, 1985 is endemic to the Hindu Kush Himalayan Region, and is currently known from a single species, T. nuristanicum (Wittmer, 1956). Here, the genus is reviewed, T. nuristanicum nom. emend. is re-described and T. kashmiricum sp. nov. is described from Kashmir Himalayan Region of India. Descriptions, diagnoses, high quality images, distribution maps and identification keys are presented. The morphology and distribution of Trypheridium are discussed and compared with those of the closely related genus Trypherus LeConte, 1851.
Serratacosa, a new genus of Lycosidae (Araneae) from the southern slopes of the Eastern Himalayas
(2021)
A new wolf spider genus, Serratacosa gen. nov., is erected based on the type and new species, S. medogensis gen. et sp. nov. and two newly combined species, S. himalayensis (Gravely, 1924) (from Hogna Simon, 1885) and S. multidontata (Qu, Peng & Yin, 2010) (from Pardosa C.L. Koch, 1847). All of them are from the southern slopes of the Eastern Himalayas. Descriptions of the new genera and species, and a redescription of S. multidontata are provided together with digital images, illustrations and a distribution map.
Five species of the subgenus Clessiniella of Cochlostoma (Cochlostomatidae) are recognized, viz. Cochlostoma (Clessiniella) villae (Strobel, 1851), Cochlostoma (Clessiniella) tergestinum (Westerlund, 1878), Cochlostoma (Clessiniella) waldemari (A.J. Wagner, 1897), Cochlostoma (Clessiniella) anomphale Boeckel, 1939 and Cochlostoma (Clessiniella) stelucarum sp. nov. The shells and the genitalia are described and the distributional data are summarized for all the species.
The present study redescribes four species of Neanthes Kinberg, 1865 (Nereididae de Blainville, 1818) based on their type specimens collected from different worldwide localities: Neanthes chilkaensis (Southern, 1921) from India, N. galetae (Fauchald, 1977) from Panama, N. helenae (Kinberg, 1865) from St Helena Island, and N. mossambica (Day, 1957) from Mozambique. The morphology of the types was re-examined for the first time after the species were originally described, and incorporated the recent improvements in the standards and terminology for describing nereidid features. The arrangement of paragnaths on area VI stood out among the diagnostic features used to distinguish these four species. Neanthes chilkaensis and N. helenae are the unique nereidids bearing p-bar paragnaths on the area VI. Both species are also distinctive as the former species only exhibited p-bar paragnaths on the area VII–VIII and the latter ventrolateral projections on the apodous segment. Further examination revealed that N. nanciae (Day, 1949) from St Helena is a junior synonym of N. helenae. Moreover, N. galetae and N. mossambica are distinguishable from other species also by the development of dorsal cirri, neuropodial postchaetal lobe and ventral ligule, the presence/absence of merged paragnaths on area IV, paired oesophageal caeca, among other features. This study has further contributed to the morphological delimitation of the species in Neanthes as a first step towards revising the genus.
Iberia has one of the richest bee faunas in the world, and the genus Andrena is no exception with around 200 species known from the Peninsula. The fauna of Andrena was largely revised in the 1970s, but since then, it has received little attention. Molecular investigation of the taxonomically challenging subgenus Taeniandrena has revealed that the situation is more complicated than previously thought with several cryptic and overlooked species. From the species allied to Andrena (T. ) gelriae van der Vecht, 1927, Andrena (T. ) gredana Warncke, 1975 stat. nov. from Spain and Portugal is raised to species status, and Andrena (T. ) levante Wood & Praz sp. nov. from southeastern Spain is newly described. Furthermore, Andrena (T. ) benoisti Wood & Praz sp. nov. is described, having previously been referred to as Andrena (T. ) wilkella beaumonti Benoist, 1961. Andrena (T. ) beaumonti stat. rev. is itself distinct and restricted to the High Atlas Mountains of Morocco. Outside of the subgenus Taeniandrena, Andrena (Euandrena) fortipunctata Wood sp. nov. and Andrena (Charitandrena) hattorfiana nigricauda Wood subsp. nov. are described from Spain, and Andrena (Notandrena) juliana Wood sp. nov. is described from Spain and Portugal. The male of Andrena (Lepidandrena) baetica Wood, 2020 is also described. Andrena (Euandrena) impressa Warncke, 1967 stat. nov. is raised to species status, displaying a West Mediterranean distribution. Finally, a further two species of Andrena are newly recorded for Spain, Andrena laurivora Warncke, 1974 and Andrena confinis Stoeckhert, 1930. Altogether, these findings reinforce the fact that our understanding of the taxonomy and distribution of Andrena in southern Europe remains incomplete.
Handaoia Seyrig, 1952 is a small genus of Phygadeuontinae currently represented by eleven described species from Madagascar, Tanzania and Europe, and can be recognized by the combination of the distally expanded and ventrally flattened antennal flagellum, complete posterior transverse carina of the mesosternum, isolated ‘pit’ (episternal scrobe) in the mesopleuron, and a single bulla in fore wing vein 2m-cu. Most species have a distinctive combined area basalis and area superomedia on the propodeum. The following six new species from Central and South America are described and illustrated: H. cuscoensis Bordera sp. nov. from Peru, H. fritzi sp. nov. from Brazil, H. mercedensis Bordera sp. nov. from Peru, H. plaumanni sp. nov. from Brazil, H. ruizcancinoi Bordera sp. nov. from Mexico, and H. urceus sp. nov. from Brazil. A key to the New World species is provided.
We here describe a new Indian helicarionoidean genus, Varadia Bhosale & Raheem gen. nov., containing the single species Varadia amboliensis Bhosale, Thackeray, Muley & Raheem gen. et sp. nov. This new semi-slug is endemic to the northern and central Western Ghats and is primarily a forest-living species. We describe and figure the shell, reproductive system, radula, spermatophore and external morphology of this new species, and detail its known distribution. We explore its relationships to other helicarionoideans using phylogenetic analyses of DNA sequence data for part of the ribosomal RNA gene cluster and discuss the morphology of the new genus in relation to other, primarily South Indian, helicarionoidean taxa. Based on characters of the reproductive system, particularly the male genitalia and the gametolytic sac, we provisionally place Varadia gen. nov. in the Macrochlamydinae (Ariophantidae). This is consistent with the results of our molecular phylogenetic analyses. The combination of large size, broad, densely tuberculated shell lobes and a shell with ca 4 whorls and a disproportionately large body whorl makes V. amboliensis gen. et sp. nov. unique among the helicarionoidean taxa of the Western Ghats. The new semi-slug is also highly distinctive in the morphology of its male genitalia.
The Acanthocinini genus Alcathousiella Monné, 2005 (Coleoptera, Cerambycidae, Lamiinae) is revised with both the genus and the type species, Alcathousiella polyrhaphoides (White, 1855) redescribed. New country records for the species, greatly expanding its known distribution in South America, are also presented. Lastly, Alcathousiella giesberti sp. nov., from Nicaragua, Costa Rica and Panama is described and illustrated.
The taxonomy of Micronectidae in Vietnam is reviewed. Based on our cumulative collections during 2001–2020, 11 new species of Micronecta Kirkaldy, 1897 are documented and described in this study: M. acuminata sp. nov., M. arcuata sp. nov., M. caperata sp. nov., M. clavata sp. nov., M. cultellata sp. nov., M. fulvopicta sp. nov., M. nieseri sp. nov., M. pingae sp. nov., M. sinuata sp. nov., M. undulata sp. nov., and M. vietnamica sp. nov. Nine species are recorded from Vietnam for the first time: M. decorata Lundblad, 1933, M. drepani Nieser, 2000, M. erythra Nieser, Chen & Yang, 2005, M. fugitans Breddin, 1905, M. johorensis Fernando, 1964, M. melanochroa Nieser, Chen & Yang, 2005, M. ornitheia Nieser, Chen & Yang, 2005, M. sahlbergi (Jakovlev, 1881), and M. tuwanoni Nieser, Chen, Leksawasdi, Thanyakam & Duangsupa, 2004. Thus, in this study, two genera and 37 species of Micronectidae are now reported from Vietnam: Synaptonecta Lundblad, 1933 with only one species, S. issa (Distant, 1910), and Micronecta with 36 species. A key to all species occurring in Vietnam, subgeneric diagnoses, and a key to all current subgenera of Micronecta are provided.
Two new species of Sonerila Roxb. (Melastomataceae), S. erectifolia Phonep., Soulad. & Tagane sp. nov. from southern Laos, and S. souvannii Phonep. & Soulad. sp. nov. from central Laos, are described and illustrated. Comparisons with morphologically similar species are presented, along with ecological information and preliminary conservation status. A key to the species of Sonerila in Laos is also provided.
New species, revision, and phylogeny of Ronzotherium Aymard, 1854 (Perissodactyla, Rhinocerotidae)
(2021)
Ronzotherium is one of the earliest Rhinocerotidae in Europe, which first appeared just after the Eocene/Oligocene transition (Grande Coupure), and became extinct at the end of the Oligocene. It is a large-sized rhinocerotid, with a special position in the phylogeny of this group, as being one of the earliest-branching true Rhinocerotidae. However, its intra-generic systematics has never been tested through computational phylogenetic methods and it is basically unknown. Its taxonomical history has gone through numerous complications, and thus we aim to provide here a complete revision of this genus, through phylogenetic methods. After a re-examination of all type specimens (five supposed species) as well as of most well-preserved specimens from all over Europe and ranging through the complete Oligocene epoch, we performed a parsimony analysis to test the position of some problematic specimens. According to our results, five species can be distinguished, Ronzotherium velaunum (type species), R. filholi, R. elongatum and R. romani as well as a new species: R. heissigi sp. nov. We also drastically re-interpret its anatomy and show that the ‘short-limbed’ “Diaceratherium” massiliae, described from Southern France, can be considered as a junior synonym of R. romani. Finally, we exclude the Asian species “Ronzotherium” orientale and “Ronzotherium” brevirostre from Ronzotherium and we consider R. kochi as a junior synonym of R. filholi.
A morphological and molecular review of the genus Goniurosaurus, including an identification key

The genus Goniurosaurus (tiger geckos) currently consists of 23 species distributed in China, Japan and Vietnam. Several species complexes and recent discoveries of cryptic species pose challenges to the species identification, which is crucial to effectively implement the recent listing of the species from China and Vietnam in CITES Appendix II and the species from Japan in CITES Appendix III. Based on the results of our field work in northern Vietnam and data compiled from literature, we herein provide a taxonomic review of the genus Goniurosaurus. Our phylogenetic analyses showed that all recorded populations of tiger geckos from Vietnam, which were found to be monophyletic with low intra-specific genetic divergences, are assigned to one of the four species: G. catbaensis, G. huuliensis, G. lichtenfelderi or G. luii. Both genetic and morphological analyses confirm that the species from China and Vietnam can be split into three major groups. Based on the newly collected data, we provide an extended morphological description of the Vietnamese species. In addition, we provide an identification key for all Goniurosaurus species from China, Japan and Vietnam in order to assist authorities in the enforcement of the recent CITES listing.
The Smicridea (Smicridea) fasciatella species group occurs from the southwestern USA, throughout Central America, the Greater Antilles islands, and most of South America, except for the Chilean subregion. It is characterized by the phallic apparatus being a simple tube with eversible internal sclerites at the apex. The fasciatella group is composed of 61 species, of which only 11 occur in Brazil, mainly in the Atlantic Forest biome in the southeastern region. In order to reduce the Linnean and Wallacean shortfalls for the Smicridea Brazilian fauna, we diagnose, describe, and illustrate males of six new species in the fasciatella group: Smicridea (Smicridea) blahniki Desiderio, Pes & Hamada sp. nov., S. (Smicridea) brevitruncata Desiderio, Pes & Hamada sp. nov., S. (Smicridea) caaguara Desiderio, Pes & Hamada sp. nov., S. (Smicridea) ipiranga Desiderio, Pes & Hamada sp. nov., S. (Smicridea) jeaneae Desiderio, Pes & Hamada sp. nov., and S. (Smicridea) polyacantha Desiderio, Pes &; Hamada sp. nov. Additionally, we provide distributional data for S. (Smicridea) albosignata Ulmer, 1907, S. (Smicridea) bivittata (Hagen, 1861), S. (Smicridea) erecta Flint, 1974, S. (Smicridea) obliqua Flint, 1974, S. (Smicridea) paranensis Flint, 1983, and S. (Smicridea) sattleri Denning & Sykora, 1968. The number of S. (Smicridea) species in Brazil increases from 21 to 27 and Smicridea is recorded from the states of Acre, Amapá, and Sergipe for the first time.
Selizitapia gen. nov. (Hemiptera: Fulgoromorpha: Flatidae) from tapia woodlands of Madagascar
(2021)
A new monotypic genus of flatid planthoppers (Hemiptera: Fulgoromorpha: Flatidae), Selizitapia gen. nov., is described for Selizitapia pennyi gen. et sp. nov. (type species) from the island of Madagascar. Habitus, male and female external and internal genital structures of the new species are illustrated and compared with similar taxa. Selizitapia pennyi gen. et sp. nov. is endemic to Madagascar where it is known to date only from one locality in the Central Plateau and is associated with tapia woodland formation.
This is the first part of a revision of the type specimens of the South American Sericini. Herein, we examine type specimens of Astaena described by Lawrence Webster Saylor (1913–1999). We provide diagnostic redescriptions, images of habitus, aedeagus, and labels of the type specimens of all 18 species described by him in the genus Astaena. We raise Sayloria Frey, 1973, a former subgenus of Symmela Erichson, 1835 that includes three species, to genus level. Our study results in the following new combinations and synonymy: Sayloria bicoloripes (Saylor, 1946) comb. nov. (= A. postnodata Frey, 1973 syn. nov.), S. abcora (Saylor, 1946) comb. nov. (= A. apolinarmaria Saylor, 1946 syn. nov.) and S. pottsi (Saylor, 1946) comb. nov.
Three new South American leafhopper genera of the tribe Gyponini are proposed: Beltrana gen. nov. based on Beltrana reticulata gen. et sp. nov. from French Guiana, Fulana gen. nov. based on Fulana brasiliensis gen. et sp. nov. from Brazil, and Sicrana gen. nov. based on Sicrana plana gen. et sp. nov. from Brazil and Ecuador. Diagnoses, detailed descriptions, and illustrations are provided for each taxon, as well as comparisons with closely related genera. In addition, the following synonyms are proposed: Freytagana DeLong, 1975 as a junior synonym of Marganana DeLong, 1948 and F. gibsoni DeLong, 1975 as a junior synonym of M. (Marganana) mexicana DeLong & Freytag, 1963. Chilella DeLong & Freytag, 1967 is transferred from Gyponini to Selenomorphini Evans, 1974.
The planthopper genus Arcofaciella Fennah, 1956 (Hemiptera: Fulgoromorpha: Delphacidae) is reviewed. Four species are recognized, of which A. obflexa Guo & Liang, 2005 and A. verrucosa Fennah, 1956 are redescribed, and one new species, A. indiana sp. nov., is described. Habitus photos for adults and illustrations of male genitalia (excluding A. penangensis (Muir, 1919)) are given. A key for identifying the species of Arcofaciella is also provided.
The Brazilian endemic irroratus species group of the genus Inca (Scarabaeidae, Cetoniinae) is defined and described. This species group is composed of Inca irroratus Chevrolat, 1833 and two new species: I. axeli sp. nov. and I. neglectus sp. nov. One new synonym is proposed: I. irroratus Chevrolat, 1833 = I. burmeisteri Burmeister, 1844 syn. nov. To guarantee nomenclatural stability, a neotype is designated for I. irroratus and a lectotype for I. burmeisteri. A key to all species of Inca and a map with the distribution of the irroratus species group are provided.
Susamyia Ziegler & Gilasian gen. nov. and its type species Susamyia mira Ziegler & Gilasian gen. et sp. nov. are described from southwestern Karkheh National Park and southeastern Jazmourian Wetland of Iran. Drawings of terminalia and head of the male as well as images of habitus, head and egg are provided. Susamyia gen. nov. is incorporated into the identification key to the Palearctic tachinid genera of Tschorsnig & Richter (1998). The systematic position of Susamyia gen. nov. in the tribe Goniini (Exoristinae) is discussed in light of molecular analyses based on the ribosomal genes 16S, 18S and 28S, and the egg type of females. The morphology of the microtype eggs was studied and compared with that of other Goniini, but proved too unreliable to be included in the phylogenetic analysis. Susamyia gen. nov. is believed to be most closely related to the goniine genera Gymnophryxe Villeneuve, 1922, Palesisa Villeneuve, 1929 and Prosopodopsis Townsend, 1926.
Taxonomic review of the genus Erythrocricus Schubart, 1962 (Diplopoda, Spirobolida, Rhinocricidae)
(2021)
We review the genus Erythrocricus Schubart, 1962 based on the type material of the species Erythrocricus sanguineostriatus (Schubart, 1962). We propose a new diagnosis, redescribe the type species, and propose a new synonymy and a new combination. In addition, a male-based key to both species recognized, including Erythrocricus electrofasciatus (Schubart, 1957), comb. nov. ex. Rhinocricus, is given.
The genus Miridiba Reitter, 1902, of phytophagous chafers from Asia, is revised based on external morphological and genital (male and female) characters. In this study, a total fifty-eight species of Miridiba were examined, and the genus is redescribed. Male genital characters of Miridiba, especially the morphology of parameres and endophallus, are studied in depth herein. The female genitalia of Miridiba are studied and described in detail for the first time. According to genital characters, nine genital morphotypes, including fifty-four species, are established under the genus Miridiba. Sixty-seven type specimens are studied. Miridiba gressitti (Frey, 1970) comb. nov., Miridiba borneensis (Moser, 1918) comb. nov., Miridiba coxalis (Arrow, 1944) comb. nov., Miridiba rugaticollis (Moser, 1913) comb. nov., Miridiba nigrescens (Moser, 1916) comb. nov., Miridiba scutata (Reitter, 1902) comb. nov., Miridiba ciliatipennis (Moser, 1903) comb. nov. and Miridiba brunneipennis (Moser, 1916) comb. nov. are transferred from Holotrichia. Holotrichia dalatensis Frey, 1970 is transferred to Miridiba as a synonym of Miridiba sinensis (Hope, 1842). Four junior subjective synonyms are proposed: Miridiba pilosella (Moser, 1908) (= Holotrichia formosana Moser, 1909), Miridiba sinensis (= Holotrichia dalatensis Frey, 1970), Miridiba scutata (= Holotrichia scutulata Dalla Torre, 1912 and Miridiba lassallei Keith, 2010). Miridiba frontalis (Fairmaire, 1886) is resurrected as a valid species. A key to 51 of the 58 valid species of Miridiba is presented.
Comanopa Blocker, 1979 and Gehundra Blocker, 1976 are small and poorly known genera of leafhoppers, previously comprising four and five species, respectively. In this study, two new species are proposed: Comanopa mananciensis sp. nov. from the state of Paraná, Southern Brazil, and Gehundra cristalinensis sp. nov. from the state of Mato Grosso, Centralwestern Brazil. The male of Gehundra sordida (Baker, 1900) is studied by the first time. Detailed descriptions and illustrations of males and females are provided and keys to males of Comanopa and Gehundra are given.
Integrative taxonomy was employed to exploit the differences between the known Metaphire anomala (Michaelsen, 1907) and other specimens collected in Vietnam. The results brought to light two new species, namely Metaphire iranomala sp. nov. and Metaphire decemtheca sp. nov. The former is easily recognised by having male pores on xix and four pairs of spermathecal pores on 5/6/7/8/9 while the latter is distinguished by having five pairs of spermathecal pores on 4/5/6/7/8/9. The K2P distances of the fragment of the cytochrome c oxidase subunit I (COI) gene are 13.1% between M. iranomala sp. nov. and M. anomala (Michaelsen, 1907) and 18% between M. decemtheca sp. nov. and Metaphire grandiverticulata Nguyen & Lam, 2017. The intraspecific divergences are 1.5%–10.6% for M. iranomala sp. nov. and 2.1%–11.4% for M. decemtheca sp. nov.
The enigmatic millipede assassin bug genus Xenorhyncocoris Miller, 1938 is revised. Previously known species, X. caraboides Miller, 1938, X. princeps Miller, 1949 and X. schoenitzeri Putshkov & Bérenger, 1999, are diagnosed and photographed. A new species, X. attractivus sp. nov., is described based on male and female specimens from northeastern Borneo. The male of Xenorhyncocoris is reported for the first time, revealing the extreme sexual dimorphism present in the genus. The diagnosis of Xenorhyncocoris is extended in order to make it applicable to the new discovery, and a female-based key to species of the genus is updated. Relationships among Xenorhyncocoris and Vilius Stål, 1863, Neozirta Distant, 1919 and Schottus Distant, 1902 are briefly discussed.
The taxonomic status of the widely distributed freshwater crab Potamonautes lirrangensis (Rathbun, 1904) sensu lato is revised because morphological and molecular evidence indicates that this taxon is a complex comprising more than one species. Four taxa are now recognized: Potamonautes lirrangensis (Rathbun, 1904) s. str. and P. kisangani sp. nov. from the Middle Congo River in Central Africa, P. amosae sp. nov. from the drainages of Lakes Kivu and Tanganyika, and P. orbitospinus (Cunnington, 1907) from Lake Malawi which had been previously synonymised with P. lirrangensis s. lat. Diagnoses, illustrations and distribution maps are provided for each of these taxa and they are compared to similar species from Central and Southern Africa.
The genus Microplitis Förster, 1862 (Hymenoptera, Braconidae, Microgastrinae) was studied from northern Iran. Specimens were collected using Malaise traps during 2010–2011. A total of 13 species were collected and identified, of which six species are recorded for the first time from Iran: M. cebes Nixon, 1970, M. docilis Nixon, 1970, M. eremitus Reinhard, 1880, M. kaszabi Papp, 1980, M. pallidipennis Tobias, 1964 and M. varipes (Ruthe, 1860). Two species M. kaszabi and M. pallidipennis are new records for the west Palaearctic region. A new species, Microplitis alborziensis Abdoli & Talebi sp. nov., is described and illustrated. The number of species of Microplitis in Iran is now raised from 17 to 24. A faunistic list, an identification key to all known Iranian species and brief diagnoses and illustrations for all species that have been collected in this study are provided. The validity of the new species is supported by DNA barcoding.
