Based on morphological comparisons and molecular evidence, a new species, Garra jiulongi is described from the upper reaches of the Salween-Nujiang River drainage in Baoshan City, Yunnan, China. It is the sixth Garra species known from the Salween-Nujiang River basin and, notably, the first Garra species whose type locality is situated in the Chinese section of the drainage. Garra jiulongi sp. no…

Four new species of the genus Ecnomus McLachlan, 1864 from China are described: E. jianfengensis Zheng & Sun, sp. nov. (Hainan), E. zhengyangorum Zheng & Sun, sp. nov. (Hainan), E. changhuaensis Zheng & Sun, sp. nov. (Hainan), and E. deformitas Zheng & Sun, sp. nov. (Yunnan). Detailed morphological descriptions, diagnostic characters, and illustrations are provided for each new sp…

The octopod fauna of the deep tropical Pacific Ocean remains poorly known, as is the octopod family Megaleledonidae Taki. A single female megaleledonid specimen collected at 1773 m depth near the equatorial Galápagos island of Darwin is named Microeledone galapagensis sp. nov. This small, squat, short-armed octopod has few arm suckers and gill lamellae. Its lack of a crop diverticulum, ink sac, a…

Cardiosciara Shah, Heller & Huang gen. nov., formerly included within Cratyna Winnertz, 1867, is described and distinguished based on clear morphological and genetic differences. Diagnostic features of the new genus include long maxillary palpi, a setose posterior pronotum, an undifferentiated tibial organ, bare posterior wing veins, and male genitalia with a distinctive tegmen that is deeply…

A new species of Leptocerus, L. bannamradensis sp. nov., is described and illustrated based on the male genitalia and molecular data. The male genitalia of L. bannamradensis sp. nov. are similar to those of L. glaukos Malicky & Chantaramongkol 2002 known from Sai Yok Waterfall, Kanchanaburi Province but differ distinctly in the inferior appendages: The basodorsal process of each inferior appe…

In this study, Mapinguaritermes marizalensis sp. nov. (Termitidae: Syntermitinae) is described based on external and internal morphological characters of workers and soldiers, as well as molecular data. The new species was collected in the Juruá River basin, central Brazilian Amazonia, and can be readily distinguished from the other congeners, M. peruanus and M. grandidens, by the soldiers’ consp…

Water bugs (Hemiptera: Heteroptera: Leptopodomorpha, Gerromorpha & Nepomorpha) are commonly found on the surface, margins, water column, or the bottom of water bodies globally. Most of them are generalist predators, feeding upon invertebrates or vertebrates, but the ingestion of algae and detritus has also been recorded in some species. Although most of their diversity is found in tropical ar…

The genus Calogalesus Kieffer, 1912 is newly recorded from Japan. Calogalesus matris sp. nov. is described as new to science based on specimens from the Ogasawara Islands and Okinawa Island, Japan. A taxonomic key to world species of Calogalesus is presented. New DNA barcodes allowed the recognition of size-related morphological variation.

Chemosymbiotic vesicomyid clams in the subfamily Pliocardiinae are a major component of deep-sea chemosynthetic ecosystems, yet their diversity remains incompletely documented. Here, we report a new species of pliocardiine clam collected from two cold seeps, the 2,526 m deep Oomine Ridge site in the Nankai Trough, Japan and the 2,915 m deep Summit Site of South Chamorro Seamount, Mariana Forearc.…

A new species of chiton, Acanthochitona pambanensis sp. nov., is described based on a small specimen collected from the intertidal zone of Pamban, Tamil Nadu, on the southeast coast of India. The new species is distinguished from other species of the genus Acanthochitona recorded from the Indian and neighbouring coasts. This new species also emphasises the limited exploration and documentation of…

The genus Limnocoris is the only genus in the New World subfamily Limnocorinae (Naucoridae) and is predominantly neotropical in distribution. Presented here is the fourth and final contribution in a series to revise the genus; the species of eastern South America are revised, including the descriptions of three new species from Brazil: L. diamantinensis sp. nov., L. hirsutus sp. nov., and L. vali…

Australian species of the Lasioglossum Curtis 1833 subgenus Ctenonomia Cameron 1903 are revised, to stabilise the taxonomy, and to facilitate identifications. This revision resolved there are 15 valid Australian species in this subgenus. Ten new species are erected, five described species are confirmed valid, six new synonyms are made and one described species has a new status. For Australian Las…

A catalogue of the Indian species of the family Zygaenidae Latreille, 1809, is presented. The documented fauna consists of 153 species belonging to 58 genera from five subfamilies, viz. Inouelinae (one species), Zygaeninae (two species), Callizygaeninae (two species), Chalcosiinae (91 species), and Procridinae (57 species). The catalogue is based primarily on literature in which Indian zygaenid s…

A new species of the genus Mimeusemia Butler, 1875 is described from India, based on integrative taxonomic approach, combining morphological and genital evidence supported by mt DNA barcode data. Superficially, the new species is reminiscent of Mimeusemia davidsoni Swinhoe, 1899 and Mimeusemia basalis (Walker, 1854) but can be readily distinguished from both by distinct phenotypical and genitalia…

The conspecificity of Iolaus lalos lalos and I. lalos kigezi was doubted based on external characters. The examination of them, supplemented by genitalia characters and distribution patterns of a series of specimens tentatively identified as I. lalos lalos or I. lalos kigezi resulted in the recognition of I. kigezi stat. nov. as a distinct species, as well as four new species, I. ungujensis sp. n…

Plecoptera (stoneflies) are aquatic insects strongly associated with clean, well-oxygenated freshwater systems, making them valuable indicators of environmental quality. In the Neotropical Realm, the genus Anacroneuria Klapálek, 1909 (Perlidae) is the most diverse, with nearly 380 described species. Here, we studied specimens of Anacroneuria from southern Brazil, describing a new species, Anacron…

Bark beetles and pinhole borers of Georgia and Kyrgyzstan were surveyed between 2003 to 2025. Specimens were collected using pheromone traps baited with Acuwit, IAC Ecolure, Sexowit, Tomowit, and ethanol; 0.5-m-long logs exposed for bark beetle colonisation; direct hand collecting in the field; searches for potential feeding substrates; and rearing from infested host material. We present 51 fauni…

In the present study, we describe a new species of Pristimantis inhabiting open ombrophilous forests of Southwestern Amazonia. We describe this new species combining mitochondrial (16S and COI) and nuclear (RAG1) loci, external morphology, bioacoustic and natural history data. The new species is phylogenetically related to other Southwestern Amazonian lowland species of the P. unistrigatus specie…

Emurena ritae Tavares sp. nov. is described from two Atlantic Forest remnants in northeastern Brazil based on morphological and molecular data. This newly discovered species reflects moth diversity in this historically underexplored region and underscores the relevance of continuing investigations in the Atlantic Forest in the course of ongoing biogeographical analyses and species surveys. An upd…
