Descrição breve
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 13; Raios dorsais moles (total) : 12; Espinhos anais: 3; Raios anais moles: 8 - 9; Vértebras: 27. It is distinguished from all congeners by the presence of three laterosensory pore foramina on the lachrymal and a unique pigmentation pattern consisting of four distinctive V-shaped black bars on the flanks superimposed on an overall whitish base (Ref. 57663). Extremely deep-bodied and laterally compressed (Ref. 57663). It has a total of six infraorbital bones (Ref. 57663). In preservative, the ground coloration is pale creamy white to yellow, body much lighter ventrally; 4 black V-shaped bands present on flanks, which extend ventrally to lateraly midline; fins pale yellow to grayish and blackish terminally, except pectoral fins (Ref. 57663).
Body shape (shape guide): short and / or deep.
Although once common throughout the region of Maroansetra, Ptychochromis makira has suffered a severe decline in abundance in recent years, according to local fishermen (Ref. 57663). They report that the species is now rare (Ref. 57663).
