Organism information awaits expert curation
Class: Actinopterygii

Size: 14 cm.

Color: In preserved specimens brownish violet, lighter below. A bluish light band, bordered by a narrow dark line, from snout to eye. A similar band from chin, where it is confluent with that of the other side, to below eye, narrowing here and continued as a broad curved band to opercle, above branchial opening. A similar curved band, above and parallel to the first, from hind border of eye to axil of pectorals, which is black. This band connected with that of other side by a band, running over occiput. A band connecting front borders of eyes and running forwards over snout is more or less distinct. A lateral bluish or light violet band on the body from nape, where it generally meets that of the other side, running at some distance below dorsal to upper caudal rays. A second band from above pectorals to middle caudal rays. The two bands connected more or less by one or two vertical narrow bands above pectoral. An oblique band from gill opening, below pectoral, running in the direction of anal, but generally not reaching so far. In its anterior course it is sometimes accomplished by another band, running below it. Dorsal white basally, reddish distally. A black spot between the first to third spines. Anal hyaline. Caudal yellowish, the upper and lower rays light violet, bordered by a narrow dark line. Base of caudal dark brown, this color sometimes spreading on caudal peduncle and forming a dark blotch. Pectorals yellowish, black at tip. Ventrals yellowish.

Height 3.4-3.9, 4-4.5 in length with caudal. Head 3.1-3.9, 3.7-4.2 in length with caudal. Height of head 1.2-1.4 in its length. Eye 4.4-5.3, 1.4-1.7 in snout and 1.1-1.4 in somewhat convex inter orbital space. Mouth somewhat oblique, not reaching to below anterior nostril. Teeth in a single series, the two anterior ones in the upper and lower jaw moderate canines, but the latter not much longer than the following teeth. Lips rather thick, plated, the inner plate festooned. Head naked, with exception of a rounded patch of about 5 scales on upper part of operculum. Seven or eight scales in front of dorsal. Dorsal spines short, slender, the first a little less, the last a little more than diameter of eye. Soft dorsal much higher than spinous part, the longest ray as long as snout, the fin slightly rounded behind. Origin of anal below first soft dorsal ray. First anal spine minute, third longest, as long as longest dorsal spine. Soft anal similar to soft dorsal. Pectorals half length of snout shorter than head. Ventrals without produced rays, somewhat pointed, equal to post orbital part of head. Caudal truncate, but the outer rays somewhat produced.
