Dorsale stekels (totaal) : 12; Dorsale zachte stralen (totaal) : 12; Anale stekels: 3; Anale zachte stralen: 10. Blue line under each eye. Corner of mouth and isthmus have orange cast (Ref. 26938). An irregular row of small molariform teeth inside and toward the front of the three usual rows of molars at side of upper jaw; dorsal profile of head evenly convex and not very steep (Ref. 13442).
