Etymology: Phenacogrammus: Greek, phenax, -akos = deceptive + Greek, gramma = letter, signal (Ref. 45335); concolor: Concolor, from the Latin, meaning of the same, or uniform, colour; named in reference to the absence of prominent pattern of black pigmentation along the flanks and caudal peduncle (Ref. 127185).

Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt) : 0; Rückenflossenweichstrahlen (insgesamt) : 9 - 10; Afterflossenstacheln: 0; Afterflossenweichstrahlen: 18 - 19; Wirbelzahl: 31 - 33. Diagnosis: While no ambiguous morphological autapomorphies have been located to diagnose Phenacogrammus concolor, the species is nonetheless distinguished from all congeners except P. deheyni and P. flexus in the possession of a prominent anterior expansion of the first pleural rib; it is readily differentiated from both in the absence of a dominant pigmentation patterning over the flanks and caudal peduncle; additionally, it differs from P. flexus in a shallower body depth, 24.9% of standard length vs. 27.0%, and in the possession of 7 supraneurals vs. 6 (Ref. 127185).
