Differs further from all congeners, except Hemigrammus haraldi, Hemigrammus luelingi, Hemigrammus neptunus, Hemigrammus ocellifer, Hemigrammus pretoensis, and Hemigrammus pulcher, by the possession of two humeral blotches. Diagnosed from all these species by the absence of a blotch on the caudal peduncle (vs. caudal peduncle blotch present). Lima, F.C.T. and L.M.
