Diagnosis
ReferenceDiagnosis
S. B. McDowell and C. M. Bogert 1954 (Diploglossa)Splenial extending far back, at least to the level of the coronoid process not forming a vertical suture with the angular at the level of the surangular-dentary suture; Meckelian groove closed (except anterior to the splenial) by a suture between the dorsal border of the splenial and the dental shelf of the dentary; external bony naris not prolonged backward as a slit lateral to the nasal bone but cleanly bored as a round or oval foramen; maxilla extending far back beneath orbit to behind the level of the middle of the eye; proximal bases of the teeth not expanded or fluted.
