Passive transponder implantation in Theraphosidae: A tool for traceability and conservation

  Passive transponder implantation in Theraphosidae: A tool for traceability and conservation Abstract Illegal wildlife trade represents a major global threat to biodiversity, with tarantulas among the most heavily trafficked invertebrate groups due to increasing demand in the international pet market, highlighting the urgent need for effective regulatory frameworks and reliable specimen-level traceability systems to distinguish legally bred individuals from illegally sourced ones. Individual identification is essential to support legal trade, strengthen enforcement mechanisms and reduce illegal trafficking; therefore, this study evaluated the feasibility and safety of passive integrated transponder microchip (PIT TAG) implantation for individual identification in multiple tarantula species under controlled laboratory conditions. Post-implantation parameters assessed included anaesthesia recovery time, feeding behaviour, ecdysis frequency, PIT TAG retention across successive moults...

Abstract

Herein, we redescribe Neostenotarsus guianensis (Caporiacco, 1954) nearly seven decades after its original description. In the original description of Neostenotarsus scissistylus Tesmoingt & Schmidt, 2002, we found characters incongruent with N. guianensis, namely, the purported presence of serration on the prolateral keels of the palpal bulb; a narrower apical third of the embolus; the absence of a patch of bristles on the retrolateral face of the palpal tibia and of a baso-retrolateral protuberance on metatarsus I; and a shorter and more apically situated megaspine on the retrolateral branch of the tibial apophyses. The characters from its original description are discussed. Nscissistylus stat. rev. has been revalidated until such time as the type material, or topotypic material, can be examined by future workers.
