Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| E. Vlachos 2018 | Rhinoclemmys panamaensis can be diagnosed as a member of Geoemydidae based on the full list of characters provided above and as a member of Rhinoclemmys based on a smooth transition from the dorsal margin of the gular scale to the visceral surface of the epiplastron, presence of a small axillary scale, nuchal with a strong posteromedial concavity on the ventral surface, visceral gular margin very narrow at the midline, gradually widening or flaring posteriorly and overlapping, or nearly overlapping, the humeral along the margin of the epiplastron, moderately keeled nuchal with narrow and elongate semitriangular cervical scale, and nuchal with broad sutural contact with neural I. Rhinoclemmys panamaensis differs from other Rhinoclemmys based on the presence of a quadrangular neural I, octagonal neural II, and wide gulars that form an angle greater than 90 degrees. |
