Dorsal spines (total): 12; Dorsal soft rays (total): 19 - 20; Anal spines: 2; Anal soft rays: 21.

Males possessing a fleshy, blade-like crest on head. Color pattern based on preserved specimens: dusky head, ventrally paler with slightly dusky chevron in smaller specimens or a cross mark on the largest specimen; dusky bar continuing ventrally beginning from midventral margin of orbit across lip, posteriorly alternated by paler area from diffuse dusky bar continuing ventrally from just posterior to eye across corner of mouth to ventral surface of head, contributing to formation of dusky chevron; pale upper lip and male crest with dusky spots; lateral side of body with 7-8 dark dusky bands interspersed with pale areas; anteriormost band dorsally diffused; all bands continuing onto dorsal fin; posterior bands typically dorsally forked in males and both dorsally and ventrally in females; posteriormost band expanded in largest specimen, continuing ventroposteriorly well onto caudal fin and joining dusky stripe along ventral margin of fin; dorsal-fin spines and rays variably dusky; males with distal intensely black spots on each of the first three interradial membranes; female lacking black spots; anal fin dusky and submarginally darker; spine and ray tips without pigmentation .
