Diagnosis
ReferenceDiagnosis
T. R. Lyson et al. 2019Member of Baenodda (sensu Joyce and Lyson, 2015) based on the greatly reduced dorsal lappet of the prefrontal, loss of a parietal and squamosal contact, exclusion of the opisthotic from the canalis stapedio-temporale, reduced nasals, contribution of vertebral V to the posterior margin of carapace, and midline contact of the extragulars posterior to the gulars; and of Eubaeninae (sensu Joyce and Lyson, 2015) based on the presence of multiple cervical scales, prepleurals, and a vertebral V that is wider than long.
