Diagnosis
ReferenceDiagnosis
S. E. Evans and M. Manabe 1999A scincomorph lizard characterised by the following combination of derived features :mandible short and robust with deep robust post-dentary region; posterolateral dentary process apparently overlapping coronoid laterally; medial surface of maxilla has facets for prefrontal and lacrimal and suggests the maxilla met the frontal to separate nasals and prefrontals; heterodont pleurodont dentition, with curved weakly keeled anterior teeth and short, blunt striated posterior teeth; frontals paired, sculptured and with strongly forked anterior nasal margins; cristae craniiwell-developed but not approaching in the midline; fronto-parietal suture transverse but with lateral processes separated by central interdigitated region; angles of narrow dorsolateral facets suggest postfrontal bone was furcate, clasping fronto-parietal suture; anterolateral borders of parietal without strong flanges to underlie frontals but with small pocket facets which apparently received the posterolateral corners of the frontals; postparietal processes short, triangular and almost horizontal in orientation; processes separated in midline by deep pit for processus ascendens bounded by short flanking processes.
