  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...

New data on the distribution of Textrix rubrofoliata Pesarini, 1990 (Araneae Agelenidae) in Italy

ABSTRACT

The spider Textrix rubrofoliata Pesarini, 1990 (Araneae Agelenidae), species known in Italy only in Sicily and Trentino-Alto Adige, was found and identified in Campo Calabro, province of Reggio Calabria, Calabria (Italy). This is the first record of the species for Calabria. Additional notes on taxonomy, distribution and biology are provided.
