Global climate change is impacting the ecology and biogeography of marine fishpopulations. Some species and populations could be lost if they are unable to adapt to thenew conditions or relocate to adequate habitats, while others may flourish and expand theirranges. Due to the dependence of parasitic copepods to their hosts, geographical shifts intheir distribution can reinforce the utility of the detection of changes in fish distributions asindicators of global climate change. Therefore we consider necessary to increase theknowledge of the biodiversity of parasitic copepods in the Argentinean Sea that could beused as baseline information to detect future changes in the distribution of the marine biotadriven by the global change. We provide new information on the distribution of 13 knownspecies of parasitic copepods gathered by the authors in 11 species of marine fishes fromArgentina, including 7 new host records and 9 new locality records. These species are:Bomolochus globiceps (Vervoort & Ramírez) and Nothobomolochus cresseyi Timi &Sardella (Bomolochidae); Brasilochondria riograndensis Thatcher & Pereira(Chondracanthidae); Taeniacanthus lagocephali Pearse (Taeniacanthidae); Caligusrogercresseyi Boxshall & Bravo and Metacaligus uruguayensis (Thomsen) (Caligidae);Hatschekia conifera Yamaguti (Hatschekiidae); Clavellotis pagri (Krøyer), Clavellaadunca (Strøm), Clavella bowmani Kabata and Parabrachiella amphipacifica Ho(Lernaeopodidae), and Lernanthropus leidyi Wilson and Lernanthropus caudatus Wilson(Lernanthropidae). A list of host species lacking parasitic copepods, for which largesamples were investigated by the authors, is also provided in order to compare in futuresurveys in a scenario where the outbreak of parasitic diseases could occur.
