Clés d'identification | Morphologie | Morphométrie
This species is distinguished by its colour pattern, generally brown with numerous clusters of mainly 2-3 dark polygonal spots; widely scattered white spots in the matrix between dark clusters; less than 10 large dark spots on the interorbital/snout region; a pair of large dark marks on the ventral surface of the head; a fragmented post-cephalic mark consisting of a large U-shaped dark spot with a more or less continuous white margin on the lower half, followed by a vertical row of 3, smaller clusters of 2-3 polygonal dark marks (Ref. 94061).
