Differs from Hemigrammus stictus by having a humeral spot roughly rectangular, higher than wide, with a pronounced upper, anteriorly-oriented extension,conferring an inverted-comma shape to the blotch (vs. humeral spot roughly rounded, not presenting an inverted-comma shape), and life color pattern presenting unpaired fins orange reddish (vs. caudal fin and caudal peduncle bright red in life, remaining fins translucent) (Ref. 81198).Description: Dorsal-fin rays ii, 9, 10, not including small ossification anterior to first unbranched ray, discernible only in c&s specimens, absent in two out of eight c&s individuals; anal-fin rays iv, 17-21; pectoral-fin rays i, 9-11; pelvic-fin rays typically i,7, a single specimen i,8 (Ref. 81198).
