From Taxonomic Accuracy to Toxin Naming: A Welcome Dialogue in Toxicon

  From Taxonomic Accuracy to Toxin Naming: A Welcome Dialogue in Toxicon By Luis A. Roque | Arácnido Taxonomy When I submitted my correspondence, “When tarantula venom comes from a misnamed spider: The importance of taxonomic accuracy in theraphosid toxinology,” to Toxicon , I hoped it would encourage a broader conversation. The purpose was to draw attention to a problem that benefits from the experience of people working across taxonomy, venom research, and biological databases. Dr. Volker Herzig’s response, “The need for a unified toxin nomenclature for consistent toxin naming,” is precisely the kind of engagement I hoped to see. His contribution acknowledges the importance of identifying venom-source organisms accurately while bringing another essential question into focus: How do we maintain continuity in toxin names when taxonomy and our understanding of toxin function change? Two connected challenges My original correspondence focused on the biological source of venom. In t...

First report of an ocular anomaly in Cyclosternum Ausserer, 1871 (Araneae: Theraphosidae) from Ecuador

Abstract
We report for the first time an ocular anomaly in a spider of the genus Cyclosternum Ausserer, 1871 (Theraphosidae), housed in the wet collection of the invertebrate section of the Museo de Zoología, Pontificia Universidad Católica del Ecuador, Quito, Ecuador.
