Abstract

ENGLISH:

A new Moenkhausia species is described from the middle rio Negro of Brazil. This species shares with Moenkhausia oligolepis, Moenkhausia sanctaefilomenae, and Moenkhausia pyrophthalma a reticulate body coloration and a red pigmentation on the dorsal margin of the eye. It can be distinguished from those species by the presence of a distinctive stripe on the caudal peduncle, a uniform anterior humeral blotch, and meristic and morphometric data. Priocharax ariel, Serrabrycon magoi, Microsternarchus fimbripinnus, and Acestridium martini are recorded for the first time from the middle rio Negro in Brazil.
