Systematics of the blindsnakes (Serpentes: Scolecophidia: Typhlopoidea) based on molecular and morphological evidence.

摘要: The blindsnake superfamily Typhlopoidea (Gerrhopilidae, Typhlopidae, and Xenotyphlopidae) is a diverse, widespread part of the global snake fauna. A recent systematic revision based on molecular phylogenetic analyses some morphological evidence presented preliminary solution to non-monophyly many previously recognized genera, but additional clarification needed regarding recognition species genera. We rectify these problems here with new analysis including 95 275 currently recognized, extant typhlopoids, incorporating both nuclear mitochondrial loci. supplement this data external, visceral, hemipenial morphology nearly all generate revised classification for Typhlopoidea. Based data, we re-assign Cathetorhinus from Typhlopidae Gerrhopilidae. Xenotyphlopidae maintains its current contents ( Xenotyphlops ). In one monotypic genus synonymized larger sister-group as it cannot be unambiguously diagnosed morphologically Sundatyphlops Anilios ), two genera are synonymizedwith Typhlops Antillotyphlops Cubatyphlops they not reciprocally monophyletic. Asiatyphylops renamed Argyrophis, senior synonym group. erect Lemuriatyphlops ) phylogenetically distinct species-group in Asiatyphlopinae. Fourteen eighteen typhlopid maintained four subfamilies: Afrotyphlopinae Afrotyphlops, Grypotyphlops [re-assigned Asiatyphlopinae] , Letheobia, Rhinotyphlops Asiatyphlopinae Acutotyphlops, Anilios, Cyclotyphlops, Indotyphlops, Malayotyphlops, Ramphotyphlops, Xerotyphlops Madatyphlopinae Madatyphlops Typhlopinae Amerotyphlops altered contents. Diagnoses provided 19 typhlopoid accounting species. This taxonomy provides robust platform future revisions description
