Abstract

We describe a new species of Characidium Reinhardt, 1867, from tributaries of the blackwater rivers Capanaparo, Cinaruco, Caura and Casiquiare in Apure, Bolivar and Amazonas states of Venezuela. Characidium longum is diagnosed by an extremely elongate body and a unique pigmentation pattern consisting of 13 or more black vertical bars, each with a concentrated spot of pigment at mid-body. These bars are united with a series of reddish-brown dorsal saddles, which cross over the dorsum and unite with bars from the opposite side of the body.
