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...

Abstract
Forty adult specimens of Atypus affinis were collected during one year in Asturias and Cantabria with pitfall traps emptied fortnightly. Specimens were collected in sampling places with different natural and managed plant formations. The captures show the spatial and temporal activity of the males of this species in the Cantabrian area. Their greatest activity was recorded in the first fortnight of December. Knowledge of mygalomorph spiders in the Iberian Peninsula is increasing with new faunal data, the description of new taxa, and the relocation of those already known, especially from the southeast of the Iberian Peninsula and the Balearic Islands. These changes make it necessary to update the Ibero-Balearic catalogue of the infraorder Mygalomorphae. This catalogue includes 39 species from five families. The families Atypidae, Macrothelidae, and Theraphosidae have only one species each, the family Halonoproctidae has two and the family Nemesiidae has 34 in three genera: Amblyocarenum, with one species, Iberesia, with six species and Nemesia, with 27 species.
