The genus name "longhai" is derived from the ancient place name " Longhai Mountain " in Qujing City. We suggest the Chinese common name as " AE海Dz ". Diagnosis. Shell small, discoidal. Shell surface with spiral ribs. Apex swelling and obtuse. Umbilicus opened. Aperture ovate. Body whorl near the outer lip detached. Inner lip and outer lip thickened, reflexed and smooth. Differential diagnosis. In terms of shell morphology, Longhai gen. nov. has a discoidal shell and body whorl near the outer lip detached. This distinguishes it from all other species in the family. Comparatively, only species of Saduniella Brandt, 1970 show some similarity, but Longhai gen. nov. body whorl near the outer lip detached. In addition, the characteristics of lip reflexed and apex swelling can differentiate it from species of the family Valvatidae. Distribution and ecology. This species is only found in the lake sediments of Lake Lulianghai in Qujing, Yunnan Province.
