Taggstrålar i ryggfenan (totalt) : 11; Mjukstrålar i ryggfenan (totalt) : 10 - 11; Taggstrålar i analfenan: 2; Mjukstrålar i analfenan: 10. This species is distinguished from its congeners by the following set of characters: rigid upper jaw lacking flexible lamina posteriorly, extending about 0.7-1.0 eye diameters behind posterior margin of orbit; infraorbitals all trough-like, open laterally; absence of suborbital shelf on 3rd infraorbital; D XI, 10-11; A II, 10; vertebrae 10+15-17, typically 16; posterior infraorbital pore positions all or mostly occupied by single pores; preopercular pore positions occupied by single pores; total gill rakers 33-39; spinous dorsal fin with a wide submarginal dusky stripe, and interradial membranes between spines 1-4 or 5 either with or without a dark blotch of variable size and intensity; other fins unpigmented. (Ref. 128653).
