Brasilochondria riograndensis Thatcher et Pereira, 2004 (Copepoda, Chondracanthidae) is redescribed based on newly collected material from the branchial cavity of flounder, Paralichthys orbignyanus (Valenciennes, 1842), from the coasts of Buenos Aires Province, Argentina. A number of details were overlooked and some appendages were misidentified in original description and are included herein. These are: the distribution and the number of setae and spines in the antennule, the armature and segmentation of mandible, maxillule, maxilla, and maxilliped, pedigerous segments and genitoabdomen, in both, females and males. Moreover, the geographical distribution of this parasite species is broadened.
