ABSTRACT A new species of Hyphessobrycon belonging to the Hyphessobrycon heterorhabdus species-group from the lower rio Tapajós, state of Pará, Brazil, is described. The new species is allocated into the Hyphessobrycon heterorhabdus species-group due to its color pattern, composed by an anteriorly well-defined, horizontally elongated humeral blotch that becomes diffuse and blurred posteriorly, where it overlaps with a conspicuous midlateral dark stripe that becomes blurred towards the caudal peduncle and the presence, in living specimens, of a tricolored longitudinal pattern composed by a dorsal red or reddish longitudinal stripe, a middle iridescent, golden or silvery longitudinal stripe, and a more ventrally-lying longitudinal dark pattern composed by... |

A new Corydoras species from the rio Tiquié, upper rio Negro system, Amazonas, Brazil, is described. This taxon was previously referred to as "Corydoras species 'Asher'", "Corydoras cf. reynoldsi", and "Corydoras aff. reynoldsi" in the aquarist literature. The new taxon can be distinguished from all its congeners, except Corydoras reynoldsi and C. weitzmani, by its color pattern, consisting of three large, dark blotches, the first one ("mask") on the head, across the eye; the second one on the trunk at the level of dorsal fin; and the third one on the trunk at the level of the adipose fin. It can be distinguished from Corydoras reynoldsi mainly by the development of trunk blotches; and from C. weitzmani by the presence of a dusky saddle between the dorsal... |
