A new species of a parasitic copepod, Acanthochondria helicoleni sp. nov. (Copepoda, Chondracanthidae), is described and illustrated from specimens collected within the branchial chambers of the rubio, Helicolenus lahillei Norman, 1937, from the Argentineanwaters. The new species most closely resemble A. serrani Braicovich et Timi, 2009 collected in the same region, but differs in the general measurements and proportions of the body; primarily by the relative length of neck, shape of head, shape and size of genito-abdominal tagma and relative size of the trunk postero-lateral processes.
