Figs 7B, 9K

Diagnosis

Measurements (n = 8): SH 2.8–3.1 mm, SW 1.5–1.6 mm, Wh 6.5–7.0; holotype: SH 3.0 mm, SW 1.5 mm, Wh 7.0. Dextral, penultimate whorl wider than the body whorl. Constriction immediately at the right edge of PeP in between the two lips (Fig. 9K). Two parietalis: Prt1 long and prominent; Prt2 short, hardly visible (Fig. 7B 3). One vertical palatalis running along the constriction. One horizontal palatalis (Fig. 9K). Columellaris prominent (Fig. 7B 3). Columellar tooth distinct. Protoconch smooth, Wh approx. 2.0, with very fine pits (Fig. 7B 1). Teleoconch with very strong and widely spaced radial ribs; about 4–6 ribs/ 0.5 mm on the penultimate whorl; 7–8 ribs/ 0.5 mm on the body whorl towards the aperture (Fig. 7B 2, B 4). Spiral striation present, but very weak and hardly visible. Umbilicus open, nearly covered by the outer lip. Aperture circular. Parietal wall of aperture slightly oblique along the coiling axis. Peristome with two close lips, inner lip slightly thickened and reflected; basal lip angular along the columella. Parietal wall of aperture extending beyond half the body whorl.

Etymology

The species name refers to Salghari in Nepali, meaning Sal tree ( Shorea robusta) forest, indicating the habitat from which the species was collected.

Type material

Holotype

NEPAL: Siddha Cave, Tanahun District, 695 m, Shorea robusta forest, 27.94544 N, 84.422244 E, 1 Apr. 2008, P.B. Budha leg. (CDZMTU046).

Paratypes

NEPAL: 50 shells from the type locality, same data as holotype (CDZMTU 047); 10 shells from the type locality, 4 Oct. 2008, P.B. Budha leg. (CDZMTU 047b).

Remarks

Diplommatina salgharica sp. nov. is very similar to D. exsert a (see Godwin-Austen 1886: pl. 49, figs 2, 2a), but is easily distinguished by its less tumid apical whorls and the presence of two parietal teeth. The constriction is nearly at the middle of the parietal lip in D. exserta, i.e., at the right edge of the peristome immediately to the parietal lip of the aperture.
