Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| F. de Lapparent de Broin and M. S. de la Fuente 2001 | Same for the genus and species. Carapace low (a) and wide (B), with a slight cervical notch. Part of the Acanthochelys subgroup of the Phrynops group as shown by the small size and decoration; relatively derived within the Phrynops group by the quadrangular neural 1 and moderately narrowed cervical. Primitive with respect to Acanthochelys by the moderate elongation of the anterior border of the carapace (C1), the nuchal anteriorly and posteriorly wide (D2–3), the cervical less elongated and narrowed (E-), the presence of neurals (b) and the more anteriorly placed axillary processes (P). |
