摘　　要：记述了贵州省洞穴烟管螺科真管螺属 1新种 ,即荔波真管螺Euphaedusalibonensissp .nov .,标本采自贵州省荔波县董背洞内。对新种进行了详细描述 ,并与近似种做了比较。The present paper describes a new species of the genus Euphaedusa Borttger, 1877: Euphaedusa libonensis sp. nov. The materials were collected by the authors from cave in Guizhou Province, China in 2001. Type specimens are deposited in the Institute of Zoology, Chinese Academy of Science, Beijing.Euphaedusa libonensis sp. nov. (Figs.1-3) Holotype, alt. 12.82?mm, diam. 2.62?mm; alt. of aperture 2.40?mm, diam. of aperture 1.90?mm; collected from Dongbeidong, Libo County (25°4′N, 107°8′E),Guizhou Province, China,8 July 2001. Paratypes 4 specimens,alt. 12.80-13.92?mm, diam. 2.62-2.97?mm; alt. of aperture 2.13-3.00?mm, diam. of aperture 1.75-2.13?mm; collected with holotype, 8 July 2001. Shell small, dextran, slightly thick, lustrous, non-transparent, long fusiform. Whorls 1012, moderately convex, spire high, spiral part, high tower-form, Apex blunt and the protoconch and 2 12whorls generally smooth, deeply sutured.The surface of shell dark-brown or yellowish brown in colour, and with very fine and somewhat distinct, dense, striated, coarse, oblique ribs. The aperture small, pear-shaped, the peristome continuous, thick, rather broadly reflexed. The slightly enlarged lamella superior and slender lamella inferior are visible at aperture. The slender long suturalis plica, a short palatal plica, a short principa plica, a short palatalis superior plica and a short lunar plica are visible at the right side of the body whorl. The new species is similar to Euphaedusda hunkonens Chen and Zhang, 1999, but differs obviously from the latter in the following characters: the shells dextran, with 1012, whorls (alt. 12.80-13.92?mm, diam. 2.62-2.97?mm; alt. of aperture 2.13-3.00?mm, diam. of aperture 1.75-2.13?mm), small. Apex blunt. The slightly big lamella superior and slender lamella inferior are visible at the aperture. The slender, long suturalis plica, a short palatal plica, a short principa plica, a short palatalis superior plica and a short lunar plica are visible at the right side of the body whorl. The l
