Dorsal spines (total): 14-16; Dorsal soft rays (total): 6-8; Anal spines: 3-4; Anal soft rays: 5-8. Distinguished from all congeners by the combination of the following characters: over-proportionally large head and mouth with massive jaws and hypertrophic lips in adult males, 3 infraorbital pores; a lyrate caudal fin in adult males with immaculate lemon-yellow lower lobe and vertical rows of spots in its upper bluish hyaline lobe, truncate and immaculate in females; extended first membranes of the dorsal fin, a distinct breast band in basal part of vertical bar 2 and posterior lateral spot in female; and absence of caudal peduncle spot (Ref. 75695). |
| Appears to be restricted to forest streams, with a preference for fast-flowing, cooler, and crystal-clear, acid to neutral water (Ref. 75695). A reddish morph of this species was collected in a small clearwater igarapé, about 1 meter wide and approximately 30 cm deep, with fine white sandy bottom, no submerged vegetation, rocks or pebbles, a pH of 4.8 at a temperature close to 29°C (Ref. 75695). |
