Coptocheilus

Coptocheilus is a genus of land snails with an operculum, terrestrial gastropod mollusks in the subfamily Pupinellinae of the family Pupinidae.

Description

(Original description in Latin) The acute shell is chrysalis-shaped and narrowly perforate. It displays a chestnut-brown color. The aperture appears almost disjoint from the spire and features a more or less double peristome, where the inner lamella is incised posteriorly. The operculum is horny, multispiral, circular, and flattened.
