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 edit

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]

Description edit

The length of the shell of this species is up to 3.9 mm.[6]

Species edit

Species within the genus Erhaia include:

Synonyms:

  • Erhaia chinensis Davis et al. 1985 and Erhaia chinensis Davis & Kang, 1995[3] are synonyms of Chencuia chinensis Liu & Zhang, 1979[6]

Ecology edit

Erhaia lives in streams in mountainous areas.[6]
