Etymology: Characidium: Diminutive of Charax, -akos = a fish without identification (Ref. 45335); nupelia: Named for Nupélia (Núcleo de Pesquisas em Limnologia, Ictiologia e Aqüicultura), in recognition of its role in the survey and ecological research of the fish fauna from the Manso Reservoir region, which led to the discovery of this species.
Eponymy: Nupélia (Núcleo de Pesquisas em Limnologia, Ictiologia e Aqüicultura) is an organisation that was involved in the survey and ecological research of fishes from the Manso Reservoir region, Mato Grosso, Brazil, during which this species was discovered. (Ref. 128868), visit book page.

Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
Raios dorsais (total) : 12 - 13; Raios anais : 9; Vértebras: 33. Belongs to a group of species, including Characidium xavante, distinguished uniquely by having high number (12-18) of dark, vertical bars on the body, each bar having the width of a scale. Differs from Characidium xavante by a greater number of scales
around the caudal peduncle (12 vs. 10), narrower interorbital region (interorbital distance 20.5-28.6 vs. 30.1-38.0% HL) and deeper caudal peduncle (caudal peduncle depth 46.2-57.8% vs. 35.4-44.9% HL). Additional conspicuous external characters which are not unique but are
useful in the identification of this species include absence of adipose fin, incomplete lateral line, and presence a dark blotch on the caudal peduncle (Ref. 75787).
