Diagnosis. A middle-sized Schistoloma species with a smooth, conical-ovoid shell, without any signs of a periumbilical keel.

Distribution. Schistoloma inermis is known from Northern Vietnam (Vinh Puc Province), and the Chinese Yunnan Province. The type locality (Tan-Doc) could not be located on the map.

Remarks. There are no notable differences between Pinteria croesus and S. inermis . Therefore, it is considered as junior synonym of that species.
