摘　　要：记述采自贵州省陆生贝类1新种,南江拟管螺Hemiphaedusa nanjiangensis sp.nov.,文中对新种形态特征、栖息环境进行了描述,并与其相似种进行了比较和讨论。In the present paper a new species of land snail is described. The materials were collected by the authors in Kaiyang County, Guizhou Province, China in Oct. 2005. Type specimens are deposited in the Institute of Zoology, Chinese Academy of Sciences, China.Hemiphaedusa nanjiangensis sp. nov. （Figs. 1-5）Holotype, alt. 25.1 mm, diam. 4.3 mm, alt. of aperture 3.3 mm, diam. of aperture 2.3 mm, collected from Nanjiang Gorge, Kaiyang County （27°N, 106°09′E ）, Guizhou Province, China, 3 Oct. 2005. Paratypes, 40 specimens, alt. 23.0-26.3 mm, diam. 4.1-4.5 mm, alt. of aperture 2.5-3.4 mm, diam. of aperture 2.2-2.5 mm, collected from Nanjiang Gorge, Kaiyang County （27°N, 106°09′E）, Guizhou Province, China, 3 Oct. 2005.Shell medium, thick, lustrous, fragile, slenderly fusiform. Whorls 17（1/2）, moderately convex with high spiral part,body whorl expand. Shell yellowish brown or dark-brown in colour, surface with very distinct spiral line and growth line; protoconch smooth, without spiral line. Apex blunt; suture deep. Aperture small, pear-shaped; peristome thick. Superior lamella small, visible in front view of the aperture, reaching peristome. Inferior lamella large, stout, very close to superior lamella. Principal plica thin, long and well developed; lunella present and curved; 1 superior plica unapparent, 1 meddle plica thin and short. Clausilium spoon-formed, and with a small notch in front of it; pedicle short and thick.The new species resembles Hemiphaedusa yunyangensis Chen and Zhang, 1999, but in the latter the shell is larger （31.0 mm, diam. 5.9 mm, alt. of aperture 6.3 mm, diam. of aperture 4.8 mm）, with fewer whorls （12（1/2） whorls）; the subcolumellar lamella not reaches the margin; the principal plica is absent; the lunar plica is strong; and 3-4 palatal plicae are visible at the right side of whorl.Etymology. The name of the new species is based on the specimens collected from Nanjiang Gorge.
