Morphology | Morphometrics
This relatively large species is distinguished by the following characters: denticles on dorsal midline greatly enlarged from snout to second dorsal origin; denticles on pectoral fin dorsal surface greatly enlarged in adults; no club-shaped papillae on the distal tip of the clasper; buccal papillae in mouth large and prominent on upper and lower surfaces; moderate vertebral count, 124 total vertebrae in the holotype (123 total in paratype, mean 117.8); relatively high tooth counts, 65 total upper teeth in the holotype (66 in the paratype, mean 66.3), 70 total lower teeth in the holotype (58 in paratype, mean 60.3); covered in irregularly shaped spots and reticulations on a brown background, resembling a honeycomb pattern; white spots rarely present, if present, are inconspicuous (Ref. 75585).
