Pupopsis maoxian sp. nov. Figs. 1 , 3 F, 8E; Table 2 Type material. Holotype : HBUMM-01023–specimen 1 (fms); 5 km from Fengyi Town on the road to Wenchuan County, 1574 m a.s.l., 31°39ʹ35.4ʹ N, 103°48ʹ48.7ʹ E, Maoxian County, NW Sichuan, China , 2004–X–11 , leg. M. Wu. Paratypes : HBUMM-01023–specimen 2 (fms), same data as holotype ; HBUMM-01794–specimen 1 (broken fms), Hongqi Hill (ca. 2 km south of the town of Maoxian ), Maoxian County, NW Sichuan, China , 2004–IX , leg. M. Wu. Type locality. 5 km from Fengyi Town on the road to Wenchuan County, Maoxian County, NW Sichuan. Material examined. Type material. Distribution. Sichuan ( Maoxian County). Etymology. The new species is named after the county name “ Maoxian .” The epithet is a noun in apposition. Diagnosis. Shell with 8.125 whorls. Height 8.8–8.9, diam. maj. 2.2–3.4. Parietal tooth absent. Columellar tooth prominent and expanded inward. Palatal wall with a ridge-like tooth. Shell. Fusiform; apex not acuminate; dextral; thin-shelled; solid; semitranslucent; glossy; with 8.125–8.125– 8.125 whorls. Whorls never spirally grooved; convex. Embryonic shell smooth; polished; with 1.500–1.563–1.625 whorls. Postnuclear whorls wrinkled. Suture simple. Last whorl gradually ascending toward aperture; rounded at periphery. Shell 8.8–8.8–8.9 high; 2.2–2.8– 3.4 in diam. maj. Height/diam. maj. ratio 2.64–3.36–4.08. Aperture ovate; slightly oblique; its insertions separated; 1.8–2.3–2.8 high, 2.0–2.1–2.1 wide. Ratio of shell height to aperture height 3.17–3.97–4.77. Peristome expanded; sharp. Palatal margin rounded. Palatal tooth present, ridgelike, extending approximately 1.25 whorls inward. Parietal callus indistinct; with angular tubercle. Parietal tooth absent. Columellar margin reflexed; with one prominent tooth which is expanded inward. Umbilicus a narrow slit. Shell uniformly light brownish-white; aperture white. Remarks. This new species is grouped into the genus Pupopsis because of its typical apertural armature. The unique shell contour with a pointed apex and a narrowed body whorl, and the combination of the absence of a parietal tooth and the presence of both palatal, ridge-like tooth and columellar tooth set P. m a o x i a n apart from all other species in the genus. This new species lives in a habitat charaterised by seasonal change of aridity and wetness. The detailed environmental characters are almost the same as described in Wu et al . (2003) for Cathaica ( Pliocathaica ) radiata Pilsbry, 1934 .
