(6) chin and throat of adults dark purplish brown with black and while ocelli (vs. pale tan to orange, immaculate or with faint white spots in some specimens). (7) pretemporal absent or much reduced (length less than half that of secondary temporal: vs. pretemporal invariably present and enlarged), and (8) posterior portions of parietals squared oft. with no medial cleft at parietal suture (vs. posterior tips of parietals pointed, extending caudally to form a medial inverted V-shaped cleft) (Brown et al. 2001: 17)|
