Type locality. “in montibus Naga dictis”.
Material examined. Syntype (NHMUK 1906.1.1.950), Naga Hills, coll. Blanford.
Remarks. Aperture suboval, parietal callus elongated, smeared onto the penultimate whorl and almost reaching halfway up it. Basal swelling behind peristome strongly indicated. Depression between basal swelling and peristome deep. Parietal lamella strong, end of outer part curved in the parietal direction, inner part curved slightly towards columella. Palatal wall with an elongated, sharp, elevated ridge (homologous with the lower palatal tooth) that nearly touches parietal lamella. Upper palatal tooth not conspicuous. Columellar lamella very deeply situated, its blade barely visible due to the parietal and palatal barriers. Based on the aperture shape, formation of apertural denticles, and the presence of a prominent basal swelling this species belongs to Sinoennea.
