Abstract

A new species of the clausiliid genus Synprosphyma A. J. Wagner, 1920 was identified from land snail specimens collected in the Ailao Mountains, Yuxi City, Yunnan Province, China, and is described herein as Synprosphyma heyuemingi sp. nov. The new species is characterized by a spindle-shaped shell, a strong inferior lamella extending to the peristome, a weakly emerging subcolumellar lamella not visible in oblique view of the aperture. This discovery further enriches the known diversity of Synprosphyma in Yunnan.

Key words: Anatomy, land snail, new taxon, taxonomy, Yunnan-Guizhou Plateau

摘 要

从采自中国云南省玉溪市哀牢山的陆生贝类标本中发现一瘤管螺属 Synprosphyma A. J. Wagner, 1920 新物种，本文将其描述为何氏瘤管螺 Synprosphyma heyuemingi sp. nov.。该新种以纺锤形贝壳、下板强壮并延伸至唇缘、下轴板弱显且在壳口斜视时不可见为主要特征。该发现进一步丰富了云南省瘤管螺属的多样性。
