Etymology: Ammolabrus:Greek, ammos = sand + see Labrus; dicrus:From the Greek dikros, forked, in reference to the forked caudal fin. More on authors: Randall & Carlson.

Flexible anal fin spines; 19 or 20 + 5 or 6 pored lateral line scales with single horizontal tubule, ending in a pore; scales thin and rhomboidal, those of thorax and anterior abdomen smaller than those of side of body; head naked except for 2 small scales dorsally on opercle and diagonal row of 5 partially embedded scales behind eye; no median predorsal scales; 3 small median prepelvic scales; anterior third of prepelvic region naked; branchiostegal rays 6; upper jaw strongly protrusible, median process of premaxilla extending to above anterior pupil edge; body moderately elongate, the depth 4.2-4.45 in SL; dorsal part of head from front of snout to origin of dorsal fin with a fleshy median ridge, the interorbital space high and triangular when viewed from the front; interorbital space narrowest anteriorly; caudal fin small, 1.45-1.65 in head length; pelvic fins small, 2.2-3.05 in head length (Ref. 26794).
