Erhaia
Erhaia is a genus of small to minute[3] freshwater snails with a gill and an operculum, aquatic gastropod mollusks in the family Amnicolidae.
Erhaia is the type genus of the tribe Erhaiini, which is now a synonym of the subfamily Amnicolinae.[1]
Erhaia (also within the tribe Erhaiini) was originally described as a genus within the Pomatiopsidae in 1985,[2] but Wilke et al. (2000, 2001) moved it to the Amnicolidae.[4][5]
Distribution
The distribution of Erhaia includes southern China and India.[6] The center of biodiversity of Erhaia in China is located in the provinces of Hunan, Hubei and Sichuan.[3] Distribution also includes Fujian Province.[3] There is also scattered occurrences of Erhaia in Yunnan Province.[3] These snails live in the Yangtze River drainage and in the Mekong River drainage (1 species).[6]
Descriptin
The length of the shell of this species is up to 3.9 mm.[6]
