背鰭 (合計): 9; 臀鰭: 23 - 26; 脊つい: 32. This species is distinguished from all its congeners, except diastatos, elachys, heliacus, loweae, notidanos, peugeoti and the Hyphessobrycon species of the rosy-tetra group (sensu Weitzman & Palmer, 1997), by having the dorsal-fin elongated in mature males (vs. not elongated); differs from Hyphessobrycon species of the rosy-tetra group by the absence of a dark blotch on dorsal-fin (vs. presence); differs from the remaining Hyphessobrycon species by having two humeral blotches (vs. one in heliacus, notidanos, peugeoti, loweae; humeral blotch inconspicuous or absent in elachys, diastatus); differs from diastatos, elachys, otidanos, loweae by having a higher number of branched anal-fin rays 23-26 (vs.15-18 in diastatos; 16-20 in elachys; 17-20 in notidanos; 17-21 in loweae); from heliacus by having the pelvic fin not filamentous in adult males (vs. pelvic-fin filamentous), and by chevron-like dark markings along the midline of the body absent or inconspicuous (vs. present and conspicuous); differs from peugeoti by having a silvery to yellowish color in live mature males (vs. mature males red in life), and higher number of branched anal-fin rays, 23-26, modally, 25 (vs. 21-24, modally, 22) (Ref. 128639).
Type locality of this species is a clear water river 40 m wide, 0.5-2 m deep, with swift current, rocky bottom, and reduced riparian vegetation, probably due to anthropogenic activities. Syntopic species included were Ancistrus sp., Characidium aff. zebra, Crenicichla pellegrini, Eigenmannia gr. trilineata, Farlowella amazonum , Gymnotus coropinae, Helogenes marmoratus, Hyphessobrycon sp., Leporinus maculatus, Moenkhausia comma, Moenkhausia collettii , Otocinclus mura, Pimelodella cf. howesi, Poptella compressa, Satanoperca jurupari and Tatia dunni. The stomach contents of the two paratypes included nematoids, chironomids larvae, unidentified vegetal fragments and sediments (Ref. 128639).
