Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| M. C. de la Fuente et al. 2011 | A small chelid turtle with a carapace characterized by a wide nuchal bone and a wide cervical scale. The first neural has a narrow contact with the nuchal bone. The neural series is complete and almost continuous, with the suprapygal bone. The mesoplastra are short, wide, laterally-placed, and crossed by the humeropectoral sulcus. The plastral bridge extends from the posterior part of the third peripheral bone and first costal to the seventh peripheral. Pr. cerrobarcinae differs from Pr. argentinae in the absence of contact between neural 2 and costal 1, in the absence of strong free rib extremity of the costal 1 in the peripherals 3e4, in the more posteriorly placed axillary buttress, and in the shape and proportions of the first and the second marginal scales. Pr. cerrobarcinae differs from Pr. portezuelae in its smaller size, the absence of contact between neural 2 and costal 1, the U-shaped anterior plastral lobe, the straight and convergent margins of the posterior plastral lobe, and the plastral formulas (ABD > IG > PEC = HU). |
