  Interspecific and Intraspecific Variation in Venom Proteomics, Composition, and Antivenom Efficacy of Thai Cobras (Naja spp.): Highlighting the Distinct Profile of the Newly Identified Naja fuxi Abstract Cobras ( Naja  spp.) account for a significant number of snakebite incidents in Thailand. The monocled cobra ( Naja kaouthia ) has historically been considered the only non-spitting species, but recent evidence indicates population-level diversification in central and southern regions. Additionally, a newly described non-spitting species, the mountain cobra ( Naja fuxi ), has been identified in mountainous areas. This study investigates venom variation among Thai  Naja  species and populations and evaluates the efficacy of monovalent and polyvalent Thai antivenoms. Proteomic analyses revealed that three-finger toxins dominate  Naja  venoms, whereas  N. fuxi  exhibits a distinct profile enriched in snake venom metalloproteinases and cysteine-rich...

A survey of the genus Orchestina Simon, 1882 (Araneae, Oonopidae) from Xishuangbanna, China, with descriptions of five new species

Abstract

Five new species and three known species of the genus Orchestina Simon, 1882 are recorded from Xishuangbanna, Yunnan Province: O. clavulata Tong & Li, 2011 (♂), O. colubrina Liu, Henrard & Xu, 2019 (♂♀), O. concava Tong & Li, sp. nov. (♂), O. menglun Tong & Li, sp. nov. (♂), O. subclavulata Tong & Li, sp. nov. (♂), O. truncatula Tong & Li, 2011 (♂♀), O. wengnan Tong & Li, sp. nov. (♂) and O. xui Tong & Li, sp. nov. (♂♀). The males of O. colubrina Liu, Henrard & Xu, 2019 is described for the first time. An identification key to species of the genus Orchestina from Xishuangbanna is provided.
