**A review of the species groups of the Western Hemisphere Onthophagus Latreille (Coleoptera: Scarabaeidae: Scarabaeinae) using COI barcoding and gene trees**

2025-03-17T12:26:48+13:00

Species groups of Western Hemispheric Onthophagus Latreille (Coleoptera: Scarabaeidae: Scarabaeinae: Onthophagini) are suggested using COI barcoding and gene trees and supported by congruence with external morphology, behavior, ecology, and biogeographic evidence. New species groups, complexes, and taxonomic statuses are offered, and other preexisting proposals are confirmed. No barcoding gap w as found between the intragroup and intergroup genetic distance blocks, but the average intragroup (8.38%) and intergroup (13.88%) Kimura-two-parameter distances are statistically different. The following seven preexisting species groups were supported by the congruence between the mtDNA barcode analysis and other independent evidence: O. chevrolati, O. clypeatus, O. dicranius, O. gazellinus, O. hircus, O. landolti, and O. mexicanus. Eight new species groups are suggested: O. crinitus, O. curvicornis, O. eulophus, O. hecate, O. hoepfneri, O. marginatus, O. nasutus, and O. velutinus. Possible behavioral/ecological adaptations of morphological characters are also discussed. New biogeographic and evolutionary hypotheses are also advanced. An identification key for species groups is presented.

**Four new species of Phytobia Lioy (Diptera: Agromyzidae) from the Brazilian Amazon, with an updated key to the Neotropical species**

2025-03-17T12:26:46+13:00

Four new species of Phytobia Lioy (Diptera: Agromyzidae) are described based on specimens collected in four localities from the Brazilian Amazon: P. espositae sp. nov., P. munduruku sp. nov., P. piscivora sp. nov., and P. pium sp. nov. Figures of male terminalia and photographs of type specimens are presented. In addition, P. setitibialis Sasakawa and P. pluviasilvae Boucher are newly recorded from Brazil and P. megapodema Sousa & Couri is newly recorded for the Brazilian state of Acre. In addition, an updated key to the Neotropical Phytobia species is presented.

Same but different: A systematic reassessment of the Hebius khasiensis Boulenger, 1890 (Reptilia: Squamata: Natricidae) species complex from the Indo-Burma biodiversity hotspot supports the revalidation of Natrix gilhodesi Wall, 1925 as a valid species

2025-03-17T12:26:43+13:00

This study provides new insights into the systematics of the natricid species Hebius khasiensis Boulenger sensu lato. Our findings are based on recent collections from northeast India, including the type locality in the Khasi Hills, Meghalaya, and the examination of its syntypes. There is a species named Natrix gilhodesi Wall from Kachin State, Myanmar, which is currently considered a subjective junior synonym of H. khasiensis, but molecular data based on the mitochondrial gene analysis show that populations from northeast India and Kachin, Myanmar are deeply divergent from each other. Here, we redescribe H. khasiensis and designate an adult female from its syntypes as the lectotype for the taxonomic stability of the given species. We also revalidate Natrix gilhodesi from Myanmar as a valid species of the genus Hebius based on molecular and morphological parameters.

New species, new locality records and descriptions of calling songs of Phaneropterinae from Sabah

2025-03-17T12:26:40+13:00

Based on recent sampling of orthopterans in Maliau Basin and Meligan (including near Long Pasia and Sinipung Hill), Sabah, Borneo, we present here notes on some of the katydids from the subfamily Phaneropterinae. Two new species were discovered and are described: Tapiena dimidia sp. nov. from Maliau Basin and Tapiena munae sp. nov. from Sinipung Hill near Long Pasia and Meligan. New locality records for Elbenia (Elbenia) paradigitata Gorochov, 2023, Stictophaula multa Gorochov & Voltshenkova, 2009, Holochlora falcata Tan, Liu & Ingrisch, 2024 and possibly Psyrana (Psyrana) nr. imitativa Gorochov, 2024. Calling songs of four species of Phaneropterinae are described for the first time: Elbenia (Elbenia) paradigitata Gorochov, 2023, Elbenia (Elbenia) ?tenera Brunner von Wattenwyl, 1878, Rectimarginalis ensis (Haan, 1843) and Tapiena ?incisa Karny, 1923.

**Three new species of the genus Empidideicus Becker, 1907 (Diptera, Mythicomyiidae) from Iran with the first record of the subgenus Cyrtoides Engel, 1933**

2025-03-17T12:26:37+13:00

Empidideicus (Empidideicus) ferrarius Gharali, Evenhuis & Moghbeli sp. nov.; Empidideicus (Cyrtoides) primitus Gharali, Evenhuis & Moghbeli sp. nov. and Empidideicus (Cyrtoides) reemeri Gharali & Evenhuis sp. nov. are described based on specimens collected from Iran by white pan trapping. Empidideicus primitus sp. nov. and E. reemeri sp. nov. mark the first records of the subgenus Cyrtoides from Iran, and with the description of these new species, the subgenus now contains five species in the World. Dichotomous keys to all species of the genus Empidideicus occurring in Iran and species of the subgenus Cyrtoides worldwide are presented.

Neozoarces pulcher Steindachner, 1880 vs Neozoarces steindachneri Jordan and Snyder, 1902 (Perciformes: Neozoarcidae): which species is valid, evidence on morphological and molecular-genetic data

2025-03-17T12:26:35+13:00

Series of spawning together males and females of the genus Neozoarces was studied. According to key morphological characters of the genus—proportional measurements: head length/TL, (c/TL), length of the upper jaw/head length (lmx/c), and net-like figure on the cheeks all males belong to N. pulcher species, and females—N. steindachneri. But, mitochondrial DNA analysis have demonstrated that sequences of genes (COI I and cytochrome b) at all individuals are identical. In addition, specimens of type series N. pulcher and N. steindachneri were studied and no significant interspecific differences between them were found. We came to the conclusion that fish of Neozoarces genus have well expressed sexual and age dimorphism, and only N. pulcher Steindachner 1880 species is valid.

**Two new Anaulacomera species (Orthoptera: Tettigoniidae: Phaneropterinae) and first female descriptions of A. dama and A. sylviae from protected areas in southern Brazil**

2025-03-17T12:26:28+13:00

Anaulacomera is the most diverse Latin America genus of katydids (Tettigoniidae), comprising 171 species. After conducting sampling activities in the state of Paraná, southern Brazil, within the Atlantic Forest biome, specifically in Iguaçu National Park (INP), Cabeça do Cachorro State Park (CCSP), and Rio Guarani State Park (RGSP), two new species of Anaulacomera were identified. In this study, we described Anaulacomera (Cervicercora) vieiradiasi sp. nov., sampled in INP and CCSP, and Anaulacomera (Anaulacomera) blancoi sp. nov. collected in INP and RGSP. Additionally, we provide the first descriptions of females for two previously known species: Anaulacomera (Anallomes) sylviae and Anaulacomera (Cervicercora) dama.

2025-03-17T12:26:24+13:00

Hydaticus kadumane sp. nov., belonging to the Hydaticus (Prodaticus) sexguttatus species group, is described from the Indian state Karnataka. In habitus and dorsal colouration, it is similar to several species from Borneo Island and the Philippines, but it can be undoubtedly recognised based on the shape of male genitalia. Photographs of the dorsal habitus and male median lobe of the aedeagus are provided.
