Upper surface of head (from the prefrontals) black, with a yellow median line. Pterygoideum with 11 teeth. Angulare very small, shorter than spleniale and much shorter than dentale. Dentale with 13 – 14 teeth. Quadratum long, directed downward and backward, and articulates with pterygoideum. 167 – 17 trunk vertebrae, 45 – 4 caudal vertebrae. Parapophyses without long ventral processes. Hypopophyses developed on all trunk vertebrae, they are much shorter than the spinous processes. Parapophyses without long ventral processes.
