Parafossarulus manchouricus is a species of freshwater snail with gills and an operculum, an aquatic prosobranch gastropod mollusk in the family Bithyniidae.

This species is medically important as a host for the liver fluke Clonorchis sinensis in East Asia.

Subspecies

Parafossarulus manchouricus japonicus (Pilsbry, 1901)

Description

The shell has 5.5 whorls.[2] The width of the shell is 6 mm.[2] The height of the shell is 10 mm.[2]

The haploid chromosome number of Parafossarulus manchouricus is n=17.[4][5]

Distribution

This species occurs in: Russia (Amur River basin),[6] Japan (Honshū, Kyushu and Shikoku), Korea, Taiwan[7] and China.[8]

The type locality is the Amur River and other rivers in the southern Siberia ("le fleuve Amour et divers cours d'eau de la Sibérie méridionale").[2]
