Descrição breve
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 1; Raios dorsais moles (total) : 9; Espinhos anais: 1; Raios anais moles: 5; Vértebras: 29. Pseudacanthicus pitanga is distinguished from its congener (except P. leopardus) by its color pattern with intense orange to red fins (vs. dark background color with white spots in P. serratus and P. fordii or gray background color with black blotches in P. histrix and P. spinosus);distinguished from P. leopardus by the presence of dark blotches anostomosing to form continuous zigzag bands alongside longitudinal keels; absence of blotches on ventral surface of body; faint blotches on head and all fins with orange to red color on unbranched ray and sometimes on subsequent branched rays (dark blotches conspicuous, never anostomosed; large dark blotches on ventral surface; conspicuous dark blotches on head; and red color restricted to dorsal and caudalfin rays); Pseudacanthicus pitanga can be further diagnosed from congeners by the following combination of osteological characters: contact of sphenotic with 6th infraorbital absent, lateral surface of metapterigoid channel triangular (vs. rounded in remaining species), posterior area of contact between cleithrum and coracoid ventrally expanded (vs. straight in remaining species) (Ref. 102632).
Caught for aquairum use (captured and bred) and exported to several countries, especially to Europe and the USA (Ref. 102632).
