---|---|---|
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. |
