Afropomus balanoidea is a species of freshwater snail, an aquatic gastropod mollusk in the family Ampullariidae, the apple snails and their allies.
Afropomus balanoidea is the only species in the genus Afropomus.[4] Afropomus is the type genus of the subfamily Afropominae.[5]
Based on the anatomy, mainly that of the reproductive system, Afropomus appears to be a primitive genus within the Ampullariidae.[4] This basal position of Afropomus within Ampullariidae has also been confirmed by molecular phylogeny.[6]
Subspecies
Subspecies of Afropomus balanoidea include:
- Afropomus balanoidea balanoidea (Gould, 1850)
- Afropomus balanoidea nimbae Binder, 1963[4] This subspecies from the Ivory Coast has a higher spire.
Distribution
The distribution of Afropomus balanoidea includes:
The type locality is Cape Mount in Liberia.[4]
Its presence in Ghana is uncertain.[1]
Description
The shape of the shell is ovate.[4]
The width of the shell is 20 mm.[4][7] The height of the shell is 22-23 mm.[4][7]
Ecology
Afropomus balanoidea lives in clean water in ditches, creeks and small rivers.[1][4] It requires a high concentration of oxygen.[1]
