Diagnosis Measurements (n = 3): SH 3.0– 3.2 mm , SW 1.5–1.7 mm , Wh 7.0. Dextral, penultimate whorl and the body whorl nearly equal in width, constriction at the middle of the parietal lip above the aperture ( Fig. 9N ). One parietalis, distinct towards the aperture ( Fig. 8B 3 ). One vertical palatalis along the constriction. Horizontal palatalis absent ( Fig. 9N ). Columellaris weak. Columellar tooth distinct. Protoconch smooth, Wh 1.5–2.0, with minute pits evenly distributed, radial ribs absent ( Fig. 8B 1 ). Teleoconch with strong, widely spaced, radial ribs; about 8–10 ribs/ 0.5 mm on the penultimate whorl; 13–16 ribs/ 0.5 mm on the body whorl towards the aperture ( Fig. 8B 2 , B 4 ). Spiral striation distinct. Umbilicus open. Aperture circular. Peristome with two close lips; under high magnification 6–8 thin ribs seen between the lips; basal columellar lip slightly directed towards the columella. Parietal wall of aperture not reaching the middle of the body whorl. Material examined NEPAL : 2 shells, Deurali, Langtang National Park, 2621 m , 28.1038 N , 85.3248 E , 5 Jun. 2007 , P.B. Budha leg. ( CDZMTU 062); 1 shell, Baghdwar, Chapali, Shivapuri-Nagarjun National Park, 2532 m , 27.8125 N , 85.3919 E , 23 Jun. 2007 , P.B. Budha leg. ( CDZMTU 063). Remarks Diplommatina sperata was originally described by Blanford (1862) from Myanmar (“in montibus Arakan a Pegu secernentibus”), but Kuznetsov & Schileyko (1997) reported this species from steep rocks in dense bushes in the Solukhumbu District, eastern Nepal . Nepalese shells are thinner than the alleged syntypes in NHM and have much thinner peristomal lips. Nevertheless, we provisionally assign the above Nepalese shells to D. sperata .
