Diagnosis

Measurements (n = 15): SH 2.6–3.0 mm, SW 1.2–1.4 mm, Wh 6.5–7.0. Dextral, penultimate whorl slightly wider than the body whorl. Constriction at the middle of the parietal wall ( Fig. 9DView Fig). Internally with two parietal lamellae, both Prt1 and Prt2 very short, prominent at the lodging edge of the operculum ( Figs 2BView Fig, 4AView Fig 3View Fig). Two vertical palatal lamellae: Vpt1 along the constriction and Vpt2 short, but running parallel to Vpt1. No horizontal palatal lamella ( Fig. 9DView Fig). Columellaris thin. Columellar tooth visible in the aperture. Protoconch smooth, Wh 1.5–2.0, with fine pits. Teleoconch with radial ribs visible only after the second whorl; widely spaced radial ribs; 6–7 ribs/ 0.5 mm on the penultimate whorl; 4–6 ribs/ 0.5 mm on the body whorl towards the aperture ( Fig. 4AView Fig 2View Fig, A 4View Fig). Spiral striation distinct. Umbilicus closed. Aperture circular. Peristome with two lips and expanded; lips widely spaced, sinuous at the angular edge. Outer lip slightly reflected. Operculum paucispiral, corneous, thin, transparent, slightly concave, outer surface smooth, inner surface with peripheral circular edge which is thicker at columellar margin.

Remarks

Diplommatina folliculus  is a very common, abundant and distinct species that can be distinguished from the others by its strong, widely-spaced lips and costulated radial ribs. It is distributed from the western to the eastern Himalaya. The most similar species is D. silvicola Godwin-Austen, 1886  (pl. LXV, figs 3, 3a), but D. folliculus  differs by its more slender shell and less distinct columellar tooth.
