The Cymothoidae (Crustacea, Isopoda), parasites on marine fishes, from Algerian fauna

Study of the eymothoid parasites of marine fish from Algeria, particularly in the Bejaia and Jijel gulfs, allowed us to identify nine species (Andocra frontalis, A. physodes, Nerocila bivittata, N. orbignyi, N. maculata, Ceratothoa parallela, C oestroides, C. oxyrrhynchaena, C. italica). Eight have been recorded previously, but Ceratothoa italica is a new record for the region. New hosts for Andocra frontalis, Nerocila maculata (host until now unidentified in Algeria) and Nerocila orbignyi are reported. For each parasite collected, the host fish, geographic distribution, parasitic specificity and prevalence are given. An up-to-date check-list of the fourteen species now reported from Algeria is given.
