Pseudopotamis is a genus of freshwater snails which have an operculum, aquatic gastropod mollusks in the family Pachychilidae.

Distribution

It occurs on the Torres Strait Islands.^[2]

A sister group (the closest relative) of Pseudopotamis is genus Tylomelania .^[2]Pseudopotamis and Tylomelania split in the Middle Miocene c. 19.5 Mya.^[2]

Species

Species within the genus Pseudopotamis include:

Pseudopotamis semoni Martens, 1894^[3]
Pseudopotamis supralirata (E. A. Smith, 1887) - synonym: Pseudopotamis finschi Martens, 1894 - type species^[3]

Description

Pallial oviduct evolved into an uterine brood (that release shelled juvenile snails).^[2]

Ecology

Species in the genus Pseudopotamis are ovoviviparous.^[3]^[2]
