Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| R. Lydekker 1886 (Clemmys watsoni) | The species may be defined from the characters of the shell as follows: Shell moderately vaulted, globose, broad; posterior margin entire; nuchal plate narrow, and broadest posteriorly; first vertebral narrowest anteriorly, and showing a tendency to a bellshape ; second and third vertebrals hexagonal, fourth short, narrowest posteriorly, and giving off a process jutting into the posterior border of the third; an interrupted vertebral, but no costal keel; costal areolse well-marked; suture separating the postgulars much shorter than the intergular suture. | |
| R. Garbin et al. 2020 | Hardella thurjii can be differentiated from other geoemydids by large carapace size (up to 60 cm in females), presence of hexagonal, nearly square second to fourth vertebrals, a first vertebral scute that is wider posteriorly, presence of an inflection at the margin of the gulohumeral sulcus, and an entoplastron that is not intersected by the humeropectoral sulcus. |
