Diagnosis

Measurements (n = 3): SH 3.4–3.5 mm, SW 1.7–1.8 mm, Wh 7.5. Dextral, apical whorls slowly increasing in size, resulting in a slender conical spire. Penultimate and body whorls nearly equal in width. Constriction between parietal lips of the peristome at AeP ( Fig. 9BView Fig). Two parietalis: Prt1 long and strongly developed, gradually elevated inner side of the body whorl, Prt2 short ( Fig. 3B3View Fig). Two vertical palatalis: Vpt1 stronger and close to the constriction,Vpt2 short. One long horizontal palatalis, touching the inner parietal lip ( Fig. 9BView Fig). Columellaris strong. Columellar tooth prominent. Protoconch smooth, Wh 2.0, with minute evenly distributed pits, no radial ribs ( Fig. 3BView Fig 1View Fig). Teleoconch with widely spaced radial ribs; 7–8 ribs/ 0.5 mm on the penultimate whorl; 8–10 ribs/ 0.5 mm on the body whorl towards the aperture ( Fig. 3BView Fig 2View Fig, B 4View Fig). Ribs moderately prominent. Very fine spiral striation present. Umbilicus open. Aperture inversely C-shaped, due to the straight columellar edge of the lip. Peristome with two close lips; under high magnification 2–3 ribs seen between the two lips. Parietal wall of the aperture extending to nearly halfway up the body whorl.

Material examined

NEPAL: 4 shells, Siddha Cave, Tanahun, 695 m, 27.94544 N, 84.422244 E, 24 Oct. 2008, P.B. Budha and R. Devkota leg. ( CDZMTU 024).

Remarks

The most similar species are Diplommatina exilis W.T. Blanford, 1863  from Myanmar ( Hanley & Theobald 1876: pl. 119, fig.10) and D. pullula Benson, 1859  from “Rungun on the West of Darjiling” ( Hanley & Theobald 1876: pl. 119, fig.7). Compared to D. exserta  , the apical whorls are wider in D. pullula  and more tumid in D. exilis  .
