Description synthétique
Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 1; Rayons mous dorsaux (Total) : 4 - 5; Rayons mous anaux: 9 - 10; Vertèbres: 29 - 30. Distinguished from all congeners by having a completely striped color pattern, bearing whitish elongate longitudinal irregular stripes along lateral sides of body. Adult male with a unique arrangement of modified anal fin, with the second unbranched anal-fin ray with anterior enlarged segments and a notch formed by the reduction of the second and third branched rays. Additional features useful to separate this species from all congeners include: pectoral-fin with four branched rays; 7 ribs; vertebrae 29-30; and upper caudal-fin lobe slightly elongated in mature males, same length in females (Ref. 79512).
Collected in an igarape of rivers, hidden in submerged trunk. Feeds mainly on juvenile and adult insects.
