Diagnostic Description

Distinguished from most Hyphessobrycon species (except H. taurocephalus) by the absence of an adipose fin (versus presence); and by the unique, possibly autapomorphic color pattern of mature males, which consists of a high concentration of dark chromatophores, mainly on the posterior part of the body, behind a vertical through the anal-fin origin, and the white color of the distal portions of the anal and dorsal fins.
