Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| G. L. Georgalis and W. G. Joyce 2017 | Pelodiscus gracilia can be diagnosed as a member of Pan-Trionychidae by the full list of shell characters provided for that clade above and Pelodiscus by small size, absence of a preneural,
suprascapular fontanelles that only close in mature adults, and xiphiplastra that are broader than long. Pelodiscus gracilia can be differentiated from Pelodiscus sinensis by larger costals VIII. |
