SHELL ( Fig. 88 View Figs 85–88 ; Tables 3–4 View Table 3 View Table 4 ). Slightly depressed conical-globose, with 5.25–5.75 convex whorls; protoconch smooth; teleoconch with fine, irregular wrinkles; apical side with indistinct incised spiral lines, umbilical side with more distinct spiral lines; without scaly processes; whitish with a distinct brown band above periphery; body whorl rounded; aperture almost circular; upper insertion of peristome distinctly descending; peristome expanded, reflexed and thickened; umbilicus slightly eccentric, moderately narrow, comprising 16–24% of shell diameter, hardly obscured by columellar edge.

GENITALIA ( Figs 47 View Figs 29–47 , 71 View Figs 63–71 ; Table 4 View Table 4 ). Atrium short; penis short, distal part cylindrical, proximal part slightly dilated, without penis coecum; membranaceous sheath around penis connected with proximal part of epiphallus by tissue; penial retractor runs from diaphragm to distal part of short epiphallus; flagellum long, broadest in its middle part, almost smooth, without node, tapering towards its proximal end; vas deferens narrow and long; vagina long; oviduct short; peduncle of bursa copulatrix subdivided into a short, broad distal part and a narrow and long proximal part, ending in an elongate oval bursa beside albumen gland. Right ommatophoral retractor runs between penis and vagina.
