  First catalog of spiders of Egypt (Araneae) Abstract This study provides a comprehensive catalog of the spider fauna of Egypt, comprising 389 species assigned to 197 genera and 40 families. For each species, all published locality records are compiled and accompanied by complete bibliographic references. The dataset has been carefully reviewed and critically evaluated in light of the most recent taxonomic and faunistic information. Among the recorded species, 55 (14.13%) are currently known only from Egypt and are thus considered endemic. Based on the World Spider Catalog (2026), 28 species are treated as nomina dubia, 23 species lack confirmed records from Egypt, which is not correct, 10 have to be omitted from the Egyptian list and 8 are species inquirenda. Despite the relatively high number of documented species, the Egyptian araneofauna remains insufficiently explored. Given the country’s ecological diversity and biogeographical position, further research is expected to signi...

Snakebites by Bothrops taeniatus: characteristics of snakebites involving a rare venomous snake in Brazil

ABSTRACT


Snakebites from the genus Bothrops account for up to 90% of venomous snakebites in Brazil. Among these species, Bothrops taeniatus is considered rare in Brazil, with only one reported case in the literature. Its venom has a strong hemorrhagic effect but lacks procoagulant activity, which can lead to significant variations in the neutralizing efficacy of anti-Bothrops serum. We describe the first case of severe envenomation by B. taeniatus with rapid recovery following the administration of anti-Bothrops serum in Brazil, and discuss the characteristics of B. taeniatus envenomation based on a literature review.
