ELENA V. MIKHALJOVA — Thu, 28 Oct 2021 00:00:00 +1300

The family Diplomaragnidae Attems, 1907 of the Asian part of Russia is reviewed and shown to comprise 11 genera and 60 species + 1 dubious species. Two genera and seven species are described here as new to science: Alineuma gen. nov., with type species A. rodionovi sp. nov. and Litovkia gen. nov., with the type species L. anisimovka sp. nov., Diplomaragna budilovi sp. nov., Diplomaragna dentifer sp. nov., Pacifiosoma shabalini sp. nov., Pacifiosoma acutum sp. nov., Pacifiosoma triangulatum sp. nov. Pacifiosoma asperum Mikhaljova, 2016 is recorded from the Primorsky Krai for the first time. Five genera are endemic to the Asian part of Russia. At the species level, the rate of endemism amounts to 91.7%. A key is given to all species of Diplomaragnidae presently known from Siberia and the Russian Far East. The distributions of the region’s diplomaragnids are discussed. Taxonomic remarks are provided for many species.

To date several studies have been carried out on Orthoptera fauna throughout Anatolia; however, there is no comprehensive study on the Orthoptera fauna of Hakkari Province. This study is a preliminary comprehensive research that deals with the less known Orthoptera (Insecta) fauna of Hakkari Province. In this respect, the records and possible localities were examined between the years 2018–2020 (except Kurdia uvarovi) for the Hakkari Province. Specimens were collected with the help of an insect sweep net or by hand. As a result of the field studies and literature research, it has been determined that the Orthoptera fauna in the province is represented by 51 genera and 69 species/subspecies belonging to 19 subfamilies in 8 families. In the study, 24 new records were noted for Hakkari Orthoptera fauna and Isophya iraca Maran, 1977 (syn. n), which is established as a new synonym of I. hakkarica Karabag, 1962. According to our preliminary research, the Orthoptera fauna of Hakkari includes 32 Ensiferan and 37 Caeliferan members. In the Ensifera suborder (long antennae katydids, crickets and allies), 25 species belonging to the Tettigoniidae, 5 species belonging to Gryllidae, and one species for the each of Myrmecophilidae and Gryllotalpidae families have been identified. Caelifera suborder includes 26 species belonging to the Acrididae, 9 species belonging to the Pamphagidae, and one species for each of the Pyrgomorphidae and Tetrigidae families. During the field studies, it was observed that the Uvarovistia satunini (Uvarov, 1916), Uvarovistia zebra (Uvarov, 1916) and, Bradyporus (Callimenus) latipes (Stål, 1875) species have high population densities. They “swarm” and damage the agricultural areas especially in the Durankaya, Bayköy, Bağışlı, and Kırıkdağ regions. For this reason, it is suggested that the populations of these species should be routinely monitored in agricultural areas.

We describe two new species of Parosphromenus from Indonesia based on morphological and molecular diagnoses. Parosphromenus juelinae, sp. nov., occurs on Bangka Island. Its unpaired fin coloration is similar to that of P. deissneri, but it differs from the latter in having a rounded caudal fin with a non-filamentous branched median ray and a smaller anal fin. Although the new species has the same caudal fin structure as P. bintan, it can be distinguished from the latter by its distinct unpaired fin coloration and the intense red color on the body flanks. Parosphromenus kishii, sp. nov., is found only in a single river system in Kalimantan Tengah. It is distinguished from all other congeners by the unique coloration of its caudal fin. A phylogenetic tree based on the cytochrome b (cytb) gene indicates that the two new species are distinct monophyletic groups constituting distinct phylogenetic branches from their congeners. Cytochrome b Genetic distances between Parosphromenus juelinae, sp. nov., and Parosphromenus kishii, sp. nov., and the other taxa in the phylogenetic tree range from 2.44% to 19.52% and from 8.65% to 17.28%, respectively.

Geothelphusa boreas, a new montane freshwater crab (Crustacea: Potamidae: Geothelphusa) from northeastern Taiwan, and the identity of G. hirsuta Tan & Liu, 1998

JHY-YUN SHY, HSI-TE SHIH, JEAN-JAY MAO — Thu, 28 Oct 2021 00:00:00 +1300

A new freshwater crab is described from the montane area in northeastern Taiwan based on morphological and molecular evidence. Geothelphusa boreas sp. nov., from the Fushan Botanical Garden situated around New Taipei City and Yilan County, is distinct from similar congeners by the structure of the male first gonopod and the proportions of the male thoracic sternites. In addition, after comparing the holotypes of G. takuan and G. hirsuta Tan & Liu, 1998, no substantial difference could be found. Molecular evidence from mitochondrial cytochrome oxidase subunit I also supports the recognition of the new species and the conspecificity of G. hirsuta with G. takuan.

**A new subspecies in the Turdus nudigenis complex (Aves: Turdidae) from the Cauca River valley of Colombia**

Thu, 28 Oct 2021 00:00:00 +1300

The taxonomy of the T. nudigenis complex has historically been challenging due to the uniformity in plumage among taxa, poorly known vocal variation, and allopatric distributions. Recent phylogenetic analyses have contributed to understanding relationships within the genus; however, much remains to be learned about the extent of phenotypic and genetic differentiation within taxa and its implications in species limits. Here, we analyze the taxonomic status of an enigmatic member of the T. nudigenis complex restricted to the Cauca River valley of Colombia. Our phylogenetic analyses suggest that the Cauca valley population is genetically distinctive from other members of the complex, although its sister relationships with respect to T. grayi and T. nudigenis could not be fully resolved due to paraphyly in the group. Based on similarity of plumage, calls, and biogeographic proximity we tentatively treat this taxon as a new subspecies of T. grayi. Populations from the northern Caribbean T. grayi casius/incomptus and the new taxon inhabit similar environmental conditions, being apparently isolated by the humid Nechí lowlands. A formal analysis of vocalizations coupled with a more robust genomic dataset are needed to resolve the systematic affinities and taxonomic status of several members of the T. nudigenis complex.

**A new cynipid inquiline of the genus Lithosaphonecrus (Hymenoptera: Cynipidae: Synergini) from India, with an updated key to all known species**

Thu, 28 Oct 2021 00:00:00 +1300

A new species of cynipid inquiline, Lithosaphonecrus nagalandi Melika, Lobato-Vila & Pujade-Villar, sp. nov. (Hymenoptera: Cynipidae: Synergini), is described from the state of Nagaland (India) reared from undescribed bud galls on an undetermined species of Lithocarpus (Fagaceae), thus being the first Lithosaphonecrus known from India. Description, diagnosis, data on phenology and host associations, and illustrations of the new species are given. An identification key to all known Lithosaphonecrus is also provided. The biology of the genus Lithosaphonecrus and the distribution range of Saphonecrus and Lithosaphonecrus in Asia and Oceania are discussed.

**A new species of the Genus Pelodiscus Fitzinger, 1835 (Testudines: Trionychidae) from Huangshan, Anhui, China**

Thu, 28 Oct 2021 00:00:00 +1300

A new species of the soft-shelled turtle genus Pelodiscus is described based on seven specimens from Huangshan, southern Anhui Province, China. The new species, Pelodiscus huangshanensis sp. nov., is distinguished from other species in the genus Pelodiscus by the following characteristics: (1) Small size (maximum carapace length of 101.16 mm and maximum body length of 190 mm); (2) keel high; (3) tiny yellowish-white spots on the throat; (4) no black pinstripes around the eyes; (5) white longitudinal bands on both sides of the neck in juveniles, absent in adults; (6) plastron yellowish-white, and only a dark patch on each side of the armpit; (7) many tubercles on the dorsal surface, but indistinct in the center; and (8) entoplastron “⌒” shaped. The phylogenetic relationships of the species in Pelodiscus were reconstructed using the sequences of cytochrome b (cyt b) and NADH dehydrogenase subunit 4 (ND4) genes. The new species formed a monophyletic clade with strong support. The uncorrected pairwise distances between the new species and other representatives of Pelodiscus ranged from 5.4% to 9.2% for cyt b and 4.1% to 7.6% for ND4. The new species brings the number of species of the genus Pelodiscus to six; five species are distributed in China, with three species endemic to China.
