CommentA. supernum has a heavily pigmented venter (immaculate in A. redimitum and A. landoi), a dark brown head lacking a well-defined cap or temporal band (reddish brown cephalic cap and well-defined temporal band present in A. redimitum and A. landoi), dorsal scales blackish (spotted with brown in A. redimitum and A. landoi), and a wide lateral stripe that occupies the upper half of the third and most of the fourth scale row (narrow lateral line occupying the middle of the fourth scale row in A. redimitum and A. landoi). 
EtymologyNamed after Latin “supernum” meaning celestial, in allusion to the dark (as in the celestial sky) coloration of this species.
