This genus differs from other similar tateids in having an elongate bursa copulatrix to which the bursal duct enters mid ventrally. The operculum has rudiments of pegs on its inner side. The shell is ovate-conic with a somewhat thickened peristome.
The genus is diagnosed as follows by Ponder et al. (2021).
Shell small, conical, whorls convex, with growth lines only; peristome slightly to moderately thickened, umbilicate. Operculum thin, yellowish, subpyriform, paucispiral with last whorl large, nucleus acentric; inner surface with 1 or 2 protuberances representing rudimentary pegs near nucleus. Radula with central teeth with median cusp wider and longer than adjacent cusps; lateral margins wide; innermost of two basal cusps (third outer denticle sometimes present) short, broad; basal tongue narrow. Male with prostate bean-shaped, little less than half in pallial roof. Pallial vas deferens simple. Penis with distal half parallel-sided for most of length, distally tapered, lacking lobes or processes; glands absent.
