摘　　要：记述了中国弯螺属1新种,即福州弯螺Sinoenneafuzhuouensissp.nov.。弯螺属的种类主要分布于东亚和南亚地区,对新种的形态特征进行了详细描述,并与近似种进行了比较和讨论。The genus Sinoennea Kobelt belongs to the family Streptaxidae. Its distribution range was limited in East Asia and South Asia. The present paper deals with a new species of genus Sinoennea Kobelt from China： Sinoennea fuzhouensis sp. nov. The materials were collected by the authors in Forest Park, Fuzhou City, Fujian Province, China in 2005. Type specimens are deposited in the Institute of Zoology, Chinese Academy of Sciences, Beijing. Sinoennea fuzhouensis sp. nov. （ Figs. 1-6） Holotype, alt. 5.17 mm, diam. 2.57 mm; alt. of aperture 1.86 mm, diam. of aperture 1.48 mm;collected from Forest Park, Fuzhou City, （26°0′ N, 119°3′E）, Fujian Province, China, 25 Aug. 2005. Paratypes, 36 specimens, 8 young shells specimens, alt. 4.43-5.21 mm diam. 2.43-2.58 ram; alt. of aperture 1.71-2.00 mm, diam. of aperture. 1.43-1.54 mm, collected from Forest Park, Fuzhou City, Fujian Province, China, 25 Aug. 2005. Shell small, thick, solid, smooth, lustrous, cylindrical. Whorls 7 1/2, moderately convex with high spiral part. Shells light yellow or yellow-brownish in colour, and with some curve vertically rib-stria, but the embryonic and second without rib-stria, smooth.Apex blunt and short, ovate, with deep suture. Aperture small, ear-shaped. The peristome thick, expanded and reflexed, with 1 big flake-form angular lamellae at inner lip, with two nipple-formed teeth in right lip： 1 big strong tooth in upper right lip, 1 smaller papillary tooth in below right lip. The columellar lip and outer lip perfectly straight. Umbilicus wide, deep, cavernous. The new species fairly resembles Sinoennea larvula （Heude, 1882）, but differs from the latter by the shells with 7 1/2 whorls, （alt. 5.17 mm, diam. 2.57 mm; alt of aperture 1.86 mm, diam. of aperture 1.48 mm） in the big size, with 1 big flake-form angular lamellae at inner lip, with two teeth in right lip; 1 big strong nipple-formed tooth in upper right lip, 1 smaller papillary tooth in below right lip. The latter shell big （alt. 3.5 mm, diam. 1.0 mm
