Tropidophora is a genus of land snails with an operculum, terrestrial gastropod mollusks in the family Pomatiidae.[2][3]

Distribution

[edit]

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.[4]

Species

[edit]

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]

The following species are recognised in the genus Tropidophora:[5]
