  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...

Fab or F(ab’)2 Antivenom: Which Should we use for North American Crotalids?

We read with interest a pair of articles comparing different aspects of Crotalidae polyvalent immune Fab (CroFab®, BTG International) or Crotalidae immune F(ab’)2(Anavip®, Rare Disease Therapeutics),the two principle antivenoms (AV) for North American pit viper envenomations [1, 2]. Both articles employed the Toxicology Investigators Consortium (ToxIC) North American Snake Bite Registry (NASBR), and both articles sought to determine whether one antivenom is preferable to the other. The two articles point to different answers to the question, “Which antivenom should our hospital use?”
