Pleurocera is a genus of freshwater snails with an operculum, aquatic gastropod molluscs in the family Pleuroceridae.[2]
All of the species in this genus have thick-walled high-spired shells, and some attain a length of over 4 cm (1.6 in). The shape of the shell is elongate-conic or cylindrical.[3] The sculpture of the shell is often carinate or costate.[3] The shell of larger species sometimes develops sculpturing and a small siphonal canal or siphonal notch at the base of the aperture.[3]
Opercula are paucispiral and corneous, but may be vestigial in some species, not completely closing the aperture.
The soft parts of the animal usually have a gray or brown coloration, commonly speckled with orange. The similar genus Juga has a seminal receptacle, but Pleurocera has no seminal receptacle.[3]
