Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| L. A. Tsuji et al. 2010 | Small parareptile characterized by the presence of an elongate, slender maxilla that carries at least 32 narrow, slightly recurved teeth, more than any known parareptile other than Lanthanosuchus; maxilla bears a distinct anterodorsal expansion but still allows for a lacrimal-narial contact, a feature shared with other basal parareptiles such as millerettids and convergently with pareiasaurs and bolosaurids; distinct craniodermal sculpturing consisting of small pinhead sized pits and thin radiating furrows; very short postfrontal, extending posteriorly barely farther than the frontal itself; prefrontal with wide medial flange; slit-like ventral temporal emargination involving the jugal, quadratojugal, postorbital and squamosal that is not closed at the ventral edge, differing from the ventral temporal emarginations of procolophonoids and Nyctiphruretus by the contribution of the postorbital; pterygoid flange anteriorly directed. |
