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
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.{{Cite journal |last1=Joyce |first1=Walter G. |last2=Revan |first2=Ariel |last3=Lyson |first3=Tyler R. |last4=Danilov |first4=Igor G. |date=October 2009 |title=Two New Plastomenine Softshell Turtles from the Paleocene of Montana and Wyoming |url=https://bioone.org/journals/bulletin-of-the-peabody-museum-of-natural-history/volume-50/issue-2/014.050.0202/Two-New-Plastomenine-Softshell-Turtles-from-the-Paleocene-of-Montana/10.3374/014.050.0202.full |journal=Bulletin of the Peabody Museum of Natural History |volume=50 |issue=2 |pages=307–325 |doi=10.3374/014.050.0202 |s2cid=85505337 |issn=0079-032X}}{{Cite journal |last1=Jasinski |first1=Steven E. |last2=Heckert |first2=Andrew B. |last3=Sailar |first3=Ciara |last4=Lichtig |first4=Asher J. |last5=Lucas |first5=Spencer G. |last6=Dodson |first6=Peter |date=2022-07-01 |title=A softshell turtle (Testudines: Trionychidae: Plastomeninae) from the uppermost Cretaceous (Maastrichtian) Hell Creek Formation, North Dakota, USA, with implications for the evolutionary relationships of plastomenines and other trionychids |url=https://www.sciencedirect.com/science/article/pii/S0195667122000362 |journal=Cretaceous Research |language=en |volume=135 |pages=105172 |doi=10.1016/j.cretres.2022.105172 |bibcode=2022CrRes.13505172J |s2cid=246803273 |issn=0195-6671}}
