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]

gollark: It's not necessarily harder if you can think of the problems when designing it.
gollark: If you have general AI good enough to be running the structure in the first place, it can just be on the design team.
gollark: "Humans have frequently been observed engaging in attacks against expensive infrastructure projects. Planning... New subgoal is to hijack human automated manufacturing systems and eliminate any human interference in structure operation."
gollark: That seems kind of paperclip-maximizery.
gollark: Over here, some convoluted mess of things has escalated enough that you can barely buy petrol.
