Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. H. Hutchison 2013 | This is a trionychid based on the absence of
epidermal scales, pitted sculpture of the external carapace surfaces, loss of the posteromedial spike of the entoplastron, and detachment of the epiplastra from the hyoplastra. It is placed in the Trionychinae on the basis of the absence of peripheral elements, basic boomerang shape of the entoplastron, and anterolateal orientation of the axillary spikes. It is distinguished from all other Trionychidae on the basis of the entoplastron with two lateral spikes anterior to the terminal spike producing a wing shape. |
