Type specimens are deposited in the Institute of Zoology, Chinese Academy of Sciences. Boysidia （ Bansonella ） xingyiensis sp. nov. （Figs. 1-4） Holotype. Alt, 2.00 mm, diam. 3.42 mm; alt, of aperture 1.57 mm, diam. of aperture 1.42 mm, Collected from Nahui Town, Xingyi County （25°1′N, 104°8′E）, Guizhou Province, China, 2 Oct, 2004, Paratypes 67 specimens. Alt, 1.71-2.14 mm, diam, 2.85-3.57 mm; alt. of aperture 1.28-1.43 mm, diam, of aperture 1.28-1.57 mm. Collected from Nahui Town, Xingyi County （25° 1′ N, 104° 8′ E）, Guizhou Province, China, 2 Oct. 2004. 1 Shell little, thick, luster, conic, Whorls 4 1/2, moderately convex, spire depressed-conical, embryowhorls （1-2） increased slowly, smooth, the body whorl very inflated, and slants downward, with a keel-shaped at the periphery. Shell deep yellow brown in colour, and with innumerable slender an dense growth lines spiral lines, silky. Apex blunt, suture deep. Aperture elliptical, bell-formed, very expanded and reflexed, thick, the peristome separated from body whorl, and not oblique, but aperture nearly parallel to body whorl, with 5 teeth in the aperture： 1 big flake- formed parietal lamella, 1 big infraparietal lamella, 1 flake-formed upper palatal fold, 1 small lower palata; fold, 1 nipple-formed subcolumellar lamella, Umbilicus big, with hole- formed. This new species is bigger to Boysidia （Bansonella） plicidens （Benson, 1849）, but differs obviously from the latter bigger size： the shell with whorls 4 1/2, alt, 2.00 mm, diam. 3.42 mm, The peristome separated from body whorl, and not oblique, but aperture nearly parallel to body whorl, with 5 teeth in the aperture： 1 big flake-formed parietal lamella, 1 big infraparietal lamella, 1 flake- formed upper palatal fold, 1 small lower palata; fold,1 nipple-formed subcolumellar lamella. Umbilicus big, with
