A New Species

The classification and identification of species within the genus Pseudechiniscus Thulin, 1911 has been considered almost a Sisyphean work due to an extremely high homogeneity of its members. Only recently have several contributions made progress in the taxonomy feasible through their detailed analyses of morphology and, crucially, by the re-description of the ancient, nominal species P. suillus (Ehrenberg, 1853). Herein, we focus on the Japanese representatives of this genus: P. asper, a rare species originally described from Hokkaido, and a new species P. shintai. Both taxa belong to the widespread suillus-facettalis complex. Detailed descriptions entailing DNA barcoding of four markers and illustrations of the ventral pillar patterns are indispensable for an accurate delineation of species within this genus.

Lines Of Evidence

Liopeltis is a genus of poorly known, infrequently sampled species of colubrid snakes in tropical Asia. We collected a specimen of Liopeltis from Pulau Tioman, Peninsular Malaysia, that superficially resembled L. philippina, a rare species that is endemic to the Palawan Pleistocene Aggregate Island Complex, western Philippines. We analyzed morphological and mitochondrial DNA sequence data from the Pulau Tioman specimen and found distinct differences to L. philippina and all other congeners. On the basis of these corroborated lines of evidence, the Pulau Tioman specimen is described as a new species, L. tiomanica sp. nov. The new species occurs in sympatry with L. tricolor on Pulau Tioman, and our description of L. tiomanica sp. nov. brings the number of endemic amphibians and reptiles on Pulau Tioman to 12.

Pachypops is a South American freshwater sciaenid genus characterized by having two anal-fin spines, three mental barbels, an inferior mouth, a swimbladder with a pair of short appendages anteriorly and a pair of longer appendages projected posteriorly, and the haemal spine of the first caudal distinctly expanded. Three valid Pachypops species are recognized herein. Of the six nominal species previously assigned to Pachypops, two are herein recognized as valid (Perca fourcroi and Micropogon trifilis), two are assigned to other sciaenid genera (Pachypops adspersus and Pachypops cevegei) and two are considered junior synonyms (Corvina biloba and Pachypops camposi). A seventh nominal species, Pachyurus nattereri, formerly considered a valid species of Pachyurus, is determined to be a junior synonym of Pachypops fourcroi, and lectotype and paralectotypes are designated for it. Pachypops fourcroi occurs in the Orinoco, Amazonas, Essequibo, Corantijn, and Approuague River basins, and Pachypops trifilis in rivers of Guyana and middle and lower reaches of the Rio Amazonas basin. A third valid species, Pachypops pigmaeus n. sp., is herein described from tributaries of the Rio Amazonas, Brazil.

A New Species

Between 1998 and 2012, several scientific expeditions in Dzanga-Sangha Special Reserve and Dzanga-Ndoki National Park led to the collection of many Mantodea specimens from Central African Republic (CAR). Among these specimens, several males of an undescribed species were discovered. Morphologically, this species most closely resembles to Chlidonoptera vexillum Karsch, 1892 and Chlidonoptera lestoni Roy, 1975. A new lineage was revealed by DNA barcoding. Therefore, a new species is described, Chlidonoptera roxanaesp. nov. Habitus images, genitalia illustrations and descriptions, measurement data, a key to species, natural history information, and locality data are provided. These results add to the evidence that cryptic species can be found in tropical regions, a critical issue in efforts to document global species richness. They also illustrate the value of DNA barcoding, especially when coupled with traditional taxonomic tools, in disclosing hidden diversity.

A New Species

A new species of glomeridellid millipede is described from Guizhou Province, southern China: Tonkinomeris huzhengkunisp. nov. This new epigean species differs very clearly in many structural details, being sufficiently distinct morphologically and disjunct geographically from T. napoensis Nguyen, Sierwald & Marek, 2019, the type and sole species of Tonkinomeris Nguyen, Sierwald & Marek, 2019, which was described recently from northern Vietnam. The genus Tonkinomeris is formally relegated from Glomeridae and assigned to the family Glomeridellidae, which has hitherto been considered strictly Euro-Mediterranean in distribution and is thus new to the diplopod faunas of China and Indochina. Tonkinomeris is re-diagnosed and shown to have perhaps the basalmost position in the family Glomeridellidae. Its relationships are discussed, both morphological and zoogeographical, within and outside the Glomeridellidae, which can now be considered as relict and basically Oriental in origin. Because of the still highly limited array of DNA-barcoding sequences of the COI mitochondrial gene available in the GenBank, the first molecular phylogenetic analysis of Glomerida attempted here shows our phylogram to be too deficient to consider meaningful.

A New Species

AbstractThe type material of most European nominal species previously placed in Rhoptromeris and of some other species is studied. Notes are given on the type material, 10 lectotypes are designated and the identity of the species is discussed. Three valid Rhoptromeris species are found: R. heptoma (Hartig) [type species], R. villosa (Hartig) and R. rufiventris (Giraud) n.comb. The latter is the type species of Hexamerocera Kieffer which is synonymized with Rhoptromeris. The genus Rhoptromeris is described and compared with related genera. The three species found to be valid are figured and redescribed, and also a new species, R. nigriventris, is described from Sweden. R. heptoma is an important parasitoid of Oscinella frit (L.) (Dipt.: Chloropidae).

A New Species

A new species, Hedyotis nanlingensis from Guangdong province, China, is described and illustrated. It is morphologically similar to H. nankunshanensis but differs in the smaller and more slender habit, the sessile leaves, the usually two to three secondary veins on each side of the midvein, the inflorescences with monochasial branching and the shorter style in the long-styled flowers. DNA barcoding analysis demonstrates that all accessions from H. nanlingensis form a monophyletic lineage closely related to H. cantoniensis.

A study of soil mites in the Brazilian Pantanal, southwestern Brazil, has shown the frequent occurrence of the genus Protogamasellus, especially in cultivated land. Three species were found in this study, Protogamasellus mica (Athias-Henriot), Protogamasellus sigillophorus Mineiro, Lindquist & Moraes, and a new species, Protogamasellus pantanal n. sp., which is here described. A taxonomic key for the identification of species of the genus was prepared, based on the examination of the type specimens of the new species here described, of specimens of other species found in Brazil in this and previous studies, and on the information found in the literature for other species.
