Description
Size: 18.3-20 cm.

Color: In preserved specimens bluish or brownish, lighter below, the scales of body and tail sometimes with a light, horizontal, median, streak. Five vertical dark brown or blackish bars, slightly less broad than the interspaces. The first on nape, immediately before dorsal, reaching to axil of pectoral, the second between 4th and 6th dorsal spines, ending before ventral median line, the third below 10th to 11th dorsal spines, almost reaching to origin of anal, the fourth below posterior spines and anterior rays, reaching on base of middle of anal, the fifth on middle of caudal peduncle. Dorsal and anal lighter or darker brown, the spinous dorsal sometimes almost black. Posterior part of soft dorsal and anal hyaline. A dark blotch at base of posterior dorsal rays may be present. Caudal dark or light brown, lighter distally. Pectorals yellowish hyaline, a triangular black spot at its base superiorly. Ventrals grayish.

Height 1.7-1.9, 2.4-2.6 in length with caudal. Head 3.1-3.4, 4.2-4.6 in length with caudal. Length of head 1.2-1.5 in its height. Eye 3-3.6, equal to or somewhat more or less than snout and 1-1.3 in somewhat convex inter orbital space. Mouth oblique. Maxillary reaching to below front border of eye or to below nostril in large specimens. Teeth truncate or slightly bifid, in a single series. No notch between pre- and suborbital, the edges of which are smooth. Preorbital naked, suborbital scaly posteriorly. Height of suborbital below middle of eye one fourth or one fifth of diameter of eye. 2 1/2 to 3 1/2 transverse rows of scales on preopercle, the inferior limb scaly. A narrow posterior limb naked. Scales on upper part of head reaching to between nostrils, the anterior scales smaller than the others. First dorsal spine somewhat less than eye, fourth to seventh spines longest, equal to snout and eye or somewhat less. Soft dorsal pointed, the longest rays slightly less than head. First anal spine less than half length of second, which is slightly longer than longest dorsal spines. Soft anal pointed, the longest rays slightly shorter than longest dorsal rays. Ventrals with the first ray produced, slightly shorter than pectorals and as long as head. Caudal deeply forked, the lobes pointed. Four scales between lateral line and scaly sheath of dorsal below last spine. Dorsal spines (total): 13; Dorsal soft rays (total): 11 - 14; Anal spines: 2; Anal soft rays: 11 - 13.

Oviparous, distinct pairing during breeding. Eggs are demersal and adhere to the substrate. Males guard and aerate the eggs.
