Nannostomus rubrocaudatus sp. n. is described from Peru. The new species is closely related with N. mortenthaleri and N. marginatus. The coloration of the males of N. rubrocaudatus sp. n. in life is extremly different from these species. The new species has a clearly developed sexual dichomatism, which is not to see in N. marginatus. The sexual dimorphism in the anal-fi n described by WEITZMAN & WEITZMAN (2003) for N. mortenthaleri was also found in N. rubrocaudatus sp. n. and in a „colour variety“ of N. marginatus from the rio Negro basin.
