Dorsal soft rays (total): 10-11; Anal soft rays: 22-25; Vertebrae: 34-35. Distinguished from congeners mainly by the combination of a conspicuous, relatively small and circular humeral spot, a black spot on the upper caudal-fin lobe, lower caudal-fin lobe without spot or a faint one, and middle caudal-fin rays hyaline or with dark tips. Mature males have a unique combination of two large-sized bony hooks on the anal-fin rays and tiny spines on the distal portion of all fins, which separates this new species from any other species of Characidae (Ref. 85074).
Description: Dorsal fin ii, 8 or 9; Anal fin iv, 18 -21; Pectoral fin i, 11-14; Pelvic fin i, 7 (Ref. 85074). |
