Forty-eight species in 27 genera of gastropods, including 14 new species and one new genus, are described from early- to middle-Triassic (Scythian- to Ladinian-aged) rocks from the southern Qinling Mountains of Gansu and Sichuan provinces, China. This report expands the knowledge of the biogeographic distribution of gastropods during the recovery from the end-Permian mass extinction. The new taxa include <i>Tongweispira sichuanensis,</i> new genus and new species, and the following new species: <i>Ananias guojiashanensis, Worthenia extendia, Gosseletina</i>? <i> dangchangensis, Zygites laevigatus, Trochotoma</i> (<i>Discotoma</i>) <i>gansuensis, Cheilotomona acutocarinata, Naticopsis</i> (<i>Dicosmos</i>) <i>compressus, Naticopsis</i> (<i>Discosmos</i>) <i>sichuanensis, Naticopsis</i>? <i> ribletella, Neritopsis planoplicatus, Platychilina sinensis, Platychilina obliqua,</i> and <i>Omphaloptycha gansuensis.</i> |
