An updated checklist of the herpetofauna from Isla María Cleofas, Mexico

Abstract

We provide an updated checklist of amphibians and reptiles from Isla María Cleofas, Mexico. This island is located at the Islas Marías Archipelago Biosphere Reserve on the coast of the state of Nayarit. The herpetofaunal diversity of Isla María Cleofas has been addressed for over a century; however, the literature is limited just a few scientific explorations and occasional records. In addition, previous herpetofaunal lists contain taxonomic inaccuracies, which are revised here, and recent nomenclatural changes are incorporated. Records of three newly reported species, Lampropeltis polyzona Cope, 1860, Leptophis diplotropis (Günther, 1872) and Tantilla calamarina Cope, 1866, were obtained during our fieldwork. Based on both our field observations and a literature review, the herpetofauna of Isla María Cleofas includes 16 species (two amphibians and 14 reptiles). We also review the conservation status of all species using three independent systems [NOM 059-SEMARNAT-2010, IUCN, and environmental vulnerability score (EVS)]. Finally, we discuss the likely occurrence of evolutionary independent lineages on the island.

Difícil Tarea De La Conservación De La Biodiversidad, El Caso De La Reserva De La Biosfera Islas Marías

“…Destacan por su importancia los hallazgos sobre nuevos registros de ciempiés (Scolopendra polymorpha) (Flores-Guerrero et al, 2018) y hormigas (Hymenoptera: Formicidae) (Cupul-Magaña y Vásquez-Bolaños, 2019), respectivamente. Así como el registro de dos anfibios en la Isla María Cleofas (Smilisca baudinii y Eleutherodactylus pallidus), y el reporte de un individuo Rhadinaea hesperia como parte de la herpetofauna insular de Nayarit (Nolasco-Luna et al, 2022;Nolasco-Luna et al, 2016). Los estudios sobre biodiversidad de peses revelan como las comunidades de peses están asociadas a mayores cantidades de rocas en el hecho marino (Tholan et al, 2020).…”
