Description
Size: 10.4 cm.

Color: In alcohol specimens reddish brown or yellow. A transverse black band running from origin of first dorsal to belly before anus. A black spot on lateral line at a short distance of base of caudal, which has four similar spots, arranged in a semicircle. Longitudinal rows of scales marked by black spots, more distinct posteriorly and especially large in the middle of the caudal peduncle, where they may fuse into a longitudinal band. Head with black spots. Frontborder of both dorsals, base of second dorsal and hindmargin of ventrals black. First dorsal sometimes with black spots.

Body much elevated, dorsal profile raising stepply from snout to dorsal. Height 1.8-2, 2.5-2.7 in length with caudal. Head 2.2-2.8, 3.3-3.7 in length with caudal. Eye 2.1-2.8, longer than snout. Mouth oblique, maxillary reaching to below middle of eye in larger specimens. Two vertical rows of scales on praeoperculum, which is denticulated along its hind and lower border. Praeopercular ridge smooth. Villiform teeth in bands in jaw and on palatines and in a V on vomer. Origin of first dorsal somewhat behind that of ventrals, first spine minute, second longest and strongest, at least as long as headwithout snout. Third one not much shorter but the following ones decreasing rapidly in size, the hindborder of the fin being therefore vertical when the spines are erected. Spine of second dorsal about equal to snout and eye, longest soft rays longer than head without snout. First anal spine minute, second spine long, curved forward, less than head without snout, the first soft rays longer. Pectorals about equal to head without snout. Ventral spine strong, less than eye and snout. Lateral rudimentary rays of caudal more or less spiny. Caudal feebly incised. Least height of caudal peduncle equal to snout and eye.
