Ribbed-shelled Oncomelania hupensis hupensis (Gredler, 1881).
This snail subspecies belongs to the family Pomatiopsidae (Mollusca: Gastropoda), and is the intermediate host of Schistosoma japonica in China. The ribs on the shell and varix surrounding the aperture are clearly visible, and a pair of eyes and a pair of tentacles are also visible on the head, with a strong contour of the foot below. This subspecies is found only in China, and has a relatively wide distribution in regions in the middle and lower reaches of the Changjiang (Yangtze) River, where schistosomiasis is still a health problem in provinces such as Hubei, Hunan, Jiangxi, and Anhui (see article by Zhao et al., doi:10.1371/journal.pntd.0000611).
