Diagnosis
ReferenceDiagnosis
M. Wang et al. 2025A small-sized lizard, with a skull about 30 mm long across the dorsal midline, differs from all other borioteiioids in the following combination of derived characters (autapomorphies are marked by *): nasal process of the premaxilla constricted at the base, tall maxillary facial process (unlike that of Tchingisaurus and Gobinatus), a long and tapering posterodorsal projection of the maxilla (similar to Polyglyphanodon but unlike that of all other borioteiioids), lacking nasal-prefrontal contact (similar to Polyglyphanodon, Tchingisaurus and Gobinatus, but unlike that of all other borioteiioids), sculpturing on the dorsal surface of the frontals (unlike those of Adamisaurus and Paleochelco), prefrontal with a fossa on its lateral surface (similar to Funiusaurus and Yechilacerta, but distinct from all other borioteiioids), elongate and waisted frontals (differs from those of Polyglyphanodon and Yechilacerta), anterolateral process of the frontal tapering between the nasal and maxilla , tooth crown chisel-like with no denticles and cusps (similar to Funiusaurus, but unlike those of other borioteiioids), and a large caniniform tooth at the fourth maxillary tooth position.
