Distribution

These large, split-sole snails are found in Tanzania,[2] Madagascar, the Mascarenes, the Comoros and South Africa.

95-99% of Tropidophora species are endemic to Madagascar.[3]

Species

The present classification of this genus into three subgenera, 95 species and 142 varieties is complex and confused. This classification is best ignored temporarily, as it is based on subtle morphological varieties among small samples. It is also assumed that many smaller species remain to be discovered.[1]

Species within the genus Tropidophora include:

gollark: Besides, before they died, some people would realize that someone had stopped the Earth rotating or something similar.
gollark: The people at polar research stations would not *immediately* die.
gollark: It's very annoying.
gollark: We already measure it precisely enough that people have to deal with leap seconds every few years.
gollark: In a saner world, we wouldn't do such credentialism, but we do.
