First dorsal-fin height equal to second dorsal-fin height. Vertebrae 11+26. Males with a proboscis-like dermal prolongation on tip of upper lip. Head of males orange above; head below level of eye, including upper lip and its extension, black; black pigment extending onto basal portion of pectoral fin. A yellowish or bluish white line extending along edge of black mask from upper rim of upper jaw to opercle and onto pectoral-fin base. Body pale yellow with indistinct H-shaped yellowish orange to orange markings. In males, H-shaped markings diffuse, narrow pale saddle marks extending discontinuously from dorsum to midline and below. A row of reddish blotches present along lateral midline, yellowish orange spots present at dorsal-fin base, and a dark blotch comprising densely packed melanophores present at posterior base of first dorsal fin and at anterior base of second dorsal fin. Dorsal-fin spines and rays orange near distal margin of fin; membranes yellowish orange on basal half and spotted with small melanophores on distal half. Uppermost pectoral-fin rays translucent, lowermost grayish or blackish. Anal fin orange. Caudal fin pale red and semi-translucent.
