Short description Bestämningsnycklar | Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt) : 0; Mjukstrålar i ryggfenan (totalt) : 9 - 10; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 20 - 21; Ryggkotor: 31 - 32. Diagnosis: Distinguished from all congeners except Phenacogrammus deheyni and P. concolor by the presence of a prominent anterior expansion of the first pleural rib; it is further distinguished from all congeners in the possession of 6 supraneural bones vs. 7, and a characteristic zigzag pattern of black pigmentation along and below the midline extending from the posterior border of the opercle to the base of the caudal peduncle (Ref. 127185).
