Etymology: Hasemania: Because of John D. Haseman, the American collector of fishes (Ref. 45335); nambiquara: The specific epithet nambiquara refers to the Nambiquara, an indigenous group from the region of the upper Rio Tapajós drainage, near the type locality.

Max length : 2.7 cm SL male/unsexed; (Ref. 75743)
Morphology | Morphometrics
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) (Ref. 75743).
