Diagnosis
Measurements (n = 4): SH 2.7–2.9 mm, SW 1.4–1.5 mm, Wh 6.0–6.5; holotype: SH 2.8 mm, SW 1.5 mm, Wh 6.0. Dextral, penultimate whorl and body whorl nearly equal in width. Constriction at the middle of the parietal wall ( Fig. 9AView Fig). Parietalis moderate, gradually elevated inner side of the body whorl. A short horizontal palatalis near the inner edge of the peristome. Columellaris moderately developed ( Fig. 3A3View Fig). Columellar tooth weak. Protoconch smooth, Wh 1.5–2.0, with very minute evenly distributed pits, without radial ribs ( Fig. 3AView Fig 1View Fig). Teleoconch with dense radial ribs; 9–12 ribs/ 0.5 mm on the penultimate whorl; 7–9 ribs/ 0.5 mm on the body whorl towards the aperture ( Fig. 3AView Fig 2View Fig, A 4View Fig). Spiral striation present. Umbilicus open. Aperture circular. Peristome with two lips; inner lip thin; 8–10 thin ribs between the two lips ( Fig. 3AView Fig 4View Fig). Parietal wall of the aperture extending to less than half the body whorl. Operculum paucispiral, corneous, thin, transparent, slightly concave, outer surface smooth, inner surface with weak ridge at the columellar margin.
Etymology
The species name refers to the habitat of the type locality, i.e., an Abies forest.

Remarks
The shell form of D. abiesiana is similar to that of D. nana W.T. Blanford, 1865 ( Blanford 1865; Hanley & Theobald 1876: pl. 140, fig.1; Godwin-Austen 1886: pl. 49, fig. 6.), but differs by its less prominent columellar tooth, the more widely-separated radial ribs, the penultimate and body whorls of equal width, and the circular aperture.
