AN IMPRESSIVE NEW CAMAENID, ENTADELLA ENTADIFORMIS GEN. & SP N. FROM GUANGXI, CHINA (GASTROPODA: PULMONATA)

摘要

An impressive, large bodied, new camaenid species, Entadella entadiformis Pall-Gergely & Hunyadi n. sp. is described from several localities in Guangxi Province (Southern China). The new genus, Entadella Pall-Gergely & Hunyadi n. gen. includes three species: E. athrix (Moillendorff, 1901), E. cavaleriei (Bavay, 1913), and E. entadiformis n. sp., and characterized by a large, nearly flat, brownish shell with rounded body whorl, smooth or finely tuberculated embryonic whorls and a very or moderately narrow umbilicus. The penial verge is small or middle-sized with lateral opening, the penial caecum is absent, the flagellum is short, and the vagina is very short. In order to provide basis for comparison of Entadella n. gen. with the type species of the genus Camaena, the reproductive anatomy, shell and radula of a Camaena cicatricosa specimen, collected from Guangxi, China, is also described.
