There are 8-13 blotches along the lateral line, blotches progressively larger posteriorly (Fig. lb). In larger specimens blotches may be fused to form longitudinal stripe, especially in posterior half of body (9 of 29 specimens with such a longitudinal stripe). No spot present at anterior base of dorsal fin. Two dark marks at base of caudal-fin rays: the larger, more intense mark a vertically elongate dark mark in series with lateral blotches; the smaller, a dorsally situated, oval, dark spot, perhaps in series with dorsal saddles. Sexual dimorphism. In our material, the largest individuals are female; no male exceeded mm SL while several females exceeded this length, the longest of which is mm SL. Males ( SL and over) possess a large subocular flaplet (Fig. 2) below the anteroventral margin of eye and have a greater number of tubercles in the mid-body region than females. In males retrorse tubercles are present on each scale in the region between the pelvic fin and the lateral line, in well-defined rows. Tubercles are also present in females in this region, but they are scattered rather than present in rows on every scale; tubercles of females are also smaller than those of males. Above the lateral line in the mid-body region both sexes have tubercles variously scattered.
