Etymology: Erythrocharax: Derived from the Greek 'erythrus', meaning red, in reference to the bright red coloration of the adipose and caudal fin in live specimens, plus the suffix 'charax', as generally applied for genera of the Characidae; altipinnis: Derived from the Latin 'alti', meaning elongate, and 'pinnis' meaning fin, in reference to the elongate dorsal-fin rays in males.

Краткое описание
определительные ключи | морфология | морфометрия
членистые (мягкие) лучи спинного плавника (общее число) : 11; членистые (мягкие) лучи анального плавника: 24 - 26; позвонки: 34. Diagnosed from other species of the Characidae by having the pelvic bones firmly attached
through the isquiatic processes. Further differs from other characids by the possession of the following characters: nearly triangular hiatus in the musculature covering the anterior chamber of the swim bladder between the first and second pleural ribs; the pedunculate, notably expanded and distally compressed teeth in both jaws; circumorbital series represented by antorbital and four infraorbital bones with laterosensory canals not enclosed; a single tooth row in the premaxillary with the teeth perfectly aligned and similar in shape and cusp number; the first three branched dorsal-fin rays distinctly elongate in males; a bright red adipose and caudal fins in life; a conspicuous dark midlateral stripe extending from the opercle to the tip of the median caudal-fin rays; and by the absence of a humeral spot (Ref. 93035).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
