Lips rather thick, plated, the most interior plate festooned. Teeth in a single series in both jaws, those of the upper jaw curved, the two anterior ones canines. In the lower jaw the teeth gradually increase in size anteriorly, the two anterior ones moderate canines. Head naked, with exception of a few small scales in the supra-opercular region. Seven or eight scales before dorsal. Dorsal spines slender, stiff, the first equal to diameter of eye, the last one less than diameter of pupil longer. Membranes between the spines scarcely incised. Soft dorsal slightly higher than spinous part, pointed behind. Origin of anal below last dorsal spine. First anal spine minute, third slightly longer than second spine, which is as long as diameter of eye. Soft anal similar to soft dorsal. Vertical fins with a low scaly sheath. Pectorals with the top rounded, the hind margin nearly straight, slightly more than head without snout. Ventrals with the first ray prolonged, shorter than pectorals. Caudal semilunar, the outer rays much longer than the middle ones and prolonged into a filaments in large specimens. Adults are identified by the yellow lunate tail. Large males turn blue on the head that grades to green towards the tail. Adults with large yellow crescent posteriorly in caudal fin and blue pectoral fins with a large elongate pink area distally.
