🐟 Physical Description

Dorsal soft rays (total): 11; Anal soft rays: 20 - 23. Diagnosed from all other species of Hasemania by the unique presence of a broad black band, situated ventral to midlateral line, and extending from the humeral region to the caudal-fin, and by the presence of a black vertically-elongate humeral spot. Other useful distinguishing characters include a higher number of maxillary teeth with more cusps (two or three tri- to pentacuspid teeth vs. none, one, or two conical or bicuspid teeth in Hasemania hanseni, Hasemania maxilaris, Hasemania melanura, and Hasemania nana); and higher number of branched anal-fin rays (16-19 vs. 11-16 in Hasemania crenuchoides, Hasemania melanura, and Hasemania nana) .
