英文摘要：This paper described a new species of Boysidia genus, Boysidia ( Bensonella) jinpingensis sp. nov. The material studied was collected by the authors from Yunnan province (China) on 19 th, September 2013. The type specimens were deposited in the Department of Cell Biology and Medical Genetics, Kunming Medical University, Kunming. Boysidia ( Bensonella) jinpingensis sp. nov. (Fig.1: a~g) Holotype: alt. 7.20 mm, diam. 4.10 mm; alt. of aperture 2.40 mm, diam. of aperture 1.80 mm. Collected from Tongchang town, Jinping county (22°07'N, 103°02'E ), Yunnan province, China, September 19 th 2013. Paratypes: 13 specimens. alt. 7.10-7.25 mm, diam. 4.00-4.15 mm; alt. of aperture 2.36-2.45 mm, diam. of aperture 1.70-1.85 mm. Collected from Tongchang town, Jinping county (22°07'N, 103°02'E), Yunnan province, China, September 19 th 2013. Etymology: The name of the new species is based on Jinping county form where the specimens were collected. Shell small, slightly thick, no-luster, opaque, long-conic. Having 6.5 whorls, moderately convex, spire long conical, embryo-whorls (1-1.5) increased slowly, smooth, the body whorl very inflated, and slants downward, with pronounced vertical two keel-shaped at the neck of aperture. Shell yellow brown or chestnut brown in color, with innumerable slender and dense oblique growth lines and spiral lines. Apex blunt, suture deep. Aperture elliptical, bell-formed, very expanded and reflexed, thick, the peristome separated from body whorl, and the aperture oblique. The inner lip keeps close to body whorl, having loose callus. With 7 teeth in the aperture, including 1 large flake-formed angular lamella, 1 big papule-formed upper palatal fold on right aperture margin, 1 small nipple-formed lower palatal fold on aperture bottom, 1 small flake-formed basal fold on left aperture margin, 1 large flake-formed columellar lamella on columella. Umbilicus big, with hole-formed. Habitat: Boysidia ( Bensonella) jinpingensis sp. nov., as other Boysidia members, usually lives on dark and damp, and calcareous rocks and screes or fallen leaves. This new species very resembles Boysidia ( Bensonella) xiuwenensis Zhang, Luo and Zhou, 2010, but the latters shell is small, with 6.5 whorls (alt. 4.20 mm, diam. 1.90 mm, alt. of aperture 1.55 mm, diam. of aperture 1.40 mm), having 4 teeth: 1 large stout, flake-formed angular lamella, 1 bigger flexuous, flake-formed columellar lamella, 1 small nipple-formed
