AB 380 myctophid individuals of 11 different species gathered off the southwest of the islands ofTenerife and El Hierro. Through morphological, molecular and phylogenetic analysis, eightparasite species were identified in seven myctophid species. One species of copepodexoparasite: Cardiodectes bellottii (n = 4); one digenean species: Lethadena profunda (n = 16);four species of Anisakidae (n = 14): Anisakis brevispiculata (n = 1), A. simplex (sensu stricto),(n = 1), Anisakis type II (n = 8) and Pseudoterranova ceticola (n= 4); as well as two species ofacantocephalus: Bolbosoma sp. (n = 1) and Neorhadynorhynchus sp. (n = 1). The study hasunveiled a new species for science, Bolbosoma sp., and provided the first record at the CanaryIslands for C. bellottii, L. profunda, Neorhadynorhynchus sp. and A. simplex (s.s.); the latterspecies might have arrived as a parasite of fin whales (Balaenoptera physalus). A.brevispiculata and P. ceticola evidenced their complex life cycle, showing that myctophidshave a double role in their life cycles which includes the family Kogiidae. The general infectionprevalence has been low, as expected in myctophids. In the case of L. profunda and anisakids,there were differences in the prevalence among different species of myctophids, which mightbe related to the diet and distribution of their definitive hosts. There were no differences in theprevalence of parasites for the same species between the islands of Tenerife and El Hierro andthis might be explained by the large distribution of their final hosts. Stomach content analysishas been carried out to determine trophic relationships and parasitic transmission potential.
