Scales large. 4 median predorsal scales; 2 scale rows on cheek. Caudal fin slightly rounded in initial phase, retained in terminal males with protruding lobes giving a double emarginate effect. Lips cover or nearly cover dental plates. Initial-phase fish without canines; terminal males usually with 1 upper canine and 2 on lower. The initial phase is characterized by a series of irregular dark chevrons which may be difficult to see on dark individuals (Ref. 1602). The basic color may range from a pale gray to a deep mahogany (Ref. 1602). Large initial phase fish develop the dark greenish markings around the lip found in the terminal phase (Ref. 1602).
