Diagnosis |
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). Description: D ii,9; A iv,16-19; P i+9-10; V i+6-7. Scale rows between lateral line and pelvic-fin insertion 3-5 (Ref. 75743). |
