Trochorbis is a genus of freshwater snails in the family Planorbidae. The type species is Trochorbis trochoideus.
Taxonomy
[edit]This genus was originally described as a subgenus of Planorbis, named Planorbis (Trochorbis), by William Henry Benson in 1855.[1] Later authors considered Trochorbis to be synonymous with the genus Segmentina,[3][4][5] sometimes displaying it as the subgenus Planorbis (Segmentina).[6][7] In 1945, Frank C. Baker restated the group as it currently appears: its own independent genus within the subfamily Segmentininae (now tribe Segmentinini).[8] The type species is Trochorbis trochoideus.[2][8]
The genus is hypothesized to be closely related to the genus Polypylis due to similar shell characteristics.[8]
Description
[edit]Species of Trochorbis are distinguished by a disc-shaped shell where the final (body) whorl covers most of the other whorls.[9]
Species
[edit]Species within this genus include:[2]
- Trochorbis tadzhikistanica Izzatullaev, 1973
- Trochorbis trochoideus (W. H. Benson, 1836)
One species remains uncertain (incertae sedis):
- Trochorbis anastasiae Izzatullaev, 1973
