The pholcid spiders of Tunisia (Araneae: Pholcidae): new species, new records, and deep COI divergence in Holocnemus reini

  The pholcid spiders of Tunisia (Araneae: Pholcidae): new species, new records, and deep COI divergence in Holocnemus reini Abstract Tunisia features a rapid transition between Mediterranean and Saharan biogeographical zones, resulting in a high degree of environmental heterogeneity. Despite this ecological diversity, Tunisian spiders have received limited attention compared to those of neighboring Maghreb countries. Here we combine the results of recent collections in Tunisia focusing on Pholcidae with a comprehensive review of previously published information, resulting in a total of six genera and eleven species. We present first records of the genera Micropholcus Deeleman-Reinhold & Prinsen, 1987 and Spermophorides Wunderlich, 1992 for Tunisia, represented by four new species: M. kahinae Huber sp. nov., M. echebbii Huber sp. nov., S. nabilae Huber & Kmira sp. nov., S. bchirae Huber sp. nov.; in addition, we redescribe S. huberti (Senglet, 1973) from Tunisian specimens,...

Beyond Snakes: Exploring Zootoxins in Invertebrates and Lower Vertebrates

Abstract

This review explores the diversity, biochemical mechanisms, and toxicological effects of venoms and toxins secreted by lower vertebrates and invertebrates, emphasizing their ecological roles and potential therapeutic applications. While snake venoms dominate toxicology research, ancient Ayurvedic texts have documented the medicinal uses of toxins from other animals in formulations like Agadas. This study examines the relevance of Jangam Visha (animate poison) in modern toxicology, highlighting envenomation cases in rural communities, where traditional household remedies often precede hospital visits. The review discusses neurotoxins like batrachotoxin, hemolytic toxins such as tetralysin, and insect-derived compounds like cantharidin and mastoparan. Additionally, species such as blister beetles (Mylabris spp.), scorpions (Hottentotta spp.), and wasps (Vespula spp.) are explored for their toxic components and therapeutic potential. The study also addresses ongoing challenges in toxin detection, neutralization, and antidote development. By bridging historical wisdom with contemporary scientific advancements, this review offers valuable insights for forensic, ecological, and biomedical research.
