abstract (from publication):
In this paper we describe Heptapterus mandimbusu sp. n., a new species of heptapterid catfish from a small tributary of the Uruguay River Basin in Misiones, Argentina. This new species is distinguished from all other congeners by the unique coloration pattern with aggregated melanophores scattered on dorsal and lateral surface of body, forming conspicuous size-variable blotches, and the combination of a long interdorsal distance (13.8–18.9 % SL), 14-18 anal-fin rays, short maxillary barbels (52.2-74.5% HL), and the adipose fin confluent with caudal fin.
