摘　　要：记述采自云南省石林县陆生贝类1新种,大叠水真管螺Euphaedusa dadieshuiensis sp.nov.,文中对新种形态特征、栖息环境进行了描述,并对其相似种进行了分析和讨论。In the present paper a new species of land snail is described. The materials were collected by the authors in Shilin County,Yunnan Province,China,July 1996. Type specimens are deposited in the Kunming Medical University,China.Euphaedusa dadieshuiensis sp. nov. （Figs 1-6）Shell small,slender,fusiform. Sinistral,thin,translucence,fragile. Whorls 1112,moderetely convex with high spiral part,pagoda-formed,under the suture with a annular ruga in each whorl,body whorl expand,and with thick rib-stria on the back of body whorl. Shell yellowish brown or chestnut-yellow in colour,surface with very distinct obliquely spiral line and growth line,with distinct thick spiral lines on aperture nearby; protoconch smooth,without spiral line. Apex blunt,suture deep. Aperture small,pear-shaped,peristome thick,white in color. Superior lamella small,inferior lamella large,both lamellae visible in aperture,and both lamella distance very near,and the superior lamella continues into spiral lamella. Subcolumellar lamella not visible in front aperture view. Principal plica long and thin,and an short and oblique lower palatal plica visible in the right side of the last whorl （Principal plica extend to the back of the last whorl）; lunella plicae is not visible. The clausilium soup spoon-formed,and thick,without a small gap on front; pedicle long and thin.At present,a total of 75 species and subspecies of genus Euphaedusa were found in China. The new species closely resembles Euphaedusa beresowskii （Moellendorff,1902） in general structure,but differs from the latter chiefly in the shell being much bigger and with 1112 whorls,（alt. 14.76 mm,diam. 3.30 mm,alt. of aperture 2.88 mm,diam. of aperture 2.06 mm）. Superior lamella small,inferior lamella large,both lamellae visible in aperture,and both lamella distance very near,and the superior lamella continues into spiral lamella. Subcolumellar lamella not visible in front aperture view. Principal plica long and thin,and a short and oblique lower palatal plica visible in the right sid
