Etymology: Phenacogrammus: Greek, phenax, -akos = deceptive + Greek, gramma = letter, signal (Ref. 45335);  flexus: Flexus, from the Latin, meaning winding, zigzag, or sharp turn; named in reference to the prominent pattern of black pigmentation along the flanks and caudal peduncle (Ref. 127185).

Environment: milieu / climate zone / depth range / distribution range Ecology

Freshwater; benthopelagic. Tropical

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 9 - 10; Anal spines: 0; Anal soft rays: 20 - 21; Vertebrae: 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).
