Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. V. Ruiz et al. 2024 | "The new taxon is a Peirosauridae with a long rostrum that differs from the other members of the clade due to a set of unique characters (autapomorphies in bold and marked with an asterisk): distance at the anterior margin of the orbit to posterior margin of the antorbital fossa longer than the height of the antorbital fossa at the posterior margin; lateral insertion of the postorbital over the jugal in the post-orbital bar*; supratemporal rims at the level of the cranial roof; squamosal post-lateral process without ornamentation* and projected upwards*; posteroventral edge of the quadratojugal does not reach the quadrate condyles*; distal edges of the quadrate with only one plane facing posteriorly*; quadratojugal dorsal extent in medial surface ending at the same level the dorsal tip of laterotemporal fenestrae*; horizontal orientation of the paraoccipital process in occipital view*; elongated mandibular symphysis; dentary not compressed, presenting a convex lateroventral surface anterior to the mandibular fenestra; dentary with lateral concavity for reception of enlarged maxillary tooth; 14 teeth per hemimandible; 7th and 8th teeth of the dentary apart from each other and closer to 6th and 9th, respectively; teeth with smooth carinae*."
