  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 new species of the genus Scorpiops Peters, 1861 from Xizang, China (Scorpiones: Scorpiopidae)

ABSTRACT


A new species, Scorpiops rufus sp.n., from Xizang (China), is described and illustrated. The new species is mainly characterized by reddish-brown color, moderate size, carapace with small and dense granules, 17 (5 eb, 2 esb, 2 em, 4 est, 4 et) external and 6–8 (usually 7) ventral trichobothria in the pedipalp patella, chela with a length/width ratio about 2.5 in males and 2.6 in females, pedipalp chela fingers are scalloped in both sexes, pectinal teeth count 6 or 7 in males and 5 or 6 in females, pectinal fulcra absent. This brings the total number of species of Scorpiops Peters, 1861 recorded in China to 34.
