Cyclanorbinae, also known commonly as the flapshell turtles, is a subfamily of softshell turtles in the family Trionychidae. The subfamily is native to Africa and Asia.

Taxonomy[edit]

Morphological evidence supports Cyclanorbinae being the sister group to the Plastomeninae, an extinct subfamily of softshell turtles that inhabited North America from the Cretaceous to the Eocene.[1][2]

Genera[edit]

The subfamily Cyclanorbinae contains the following three extant genera.[3]

One extinct prehistoric genus is also known from fossil remains: Nemegtemys Danilov et al., 2014, from the CretaceousofMongolia.[4]

Geographic range[edit]

Species in the genera Cyclanorbis and Cycloderma are found in Africa; species in the genus Lissemys are found in Asia.[5]
