Copepods of the family Pandaridae are typically ectoparasites of elasmobranch fishes. They display a cosmopolitan distribution and limited host specificity. Published literature on their occurrence on pelagic sharks in the Mediterranean is scarce, often from the past century, or scattered through fish parasite surveys. Moreover, of the 64 valid pandarid species known at present, molecular data from GenBank exists for only 10 species and there are no data from the Mediterranean. In this study, we begin addressing this knowledge gap by exploring the molecular features of some pandarid copepods (i.e.,  Dinemoura latifolia ,  Echthrogaleus coleoptratus, Pandarus satyrus , and  Phyllothyreus cornutus ) and their phylogenetic relationships using new material from pelagic sharks (i.e.,  Prionace glauca ,  Isurus oxyrinchus , and  Carcharodon carcharias ) in the Mediterranean. Genetic distances analysis showed intraspecific variation in the mitochondrial DNA cytochrome oxidase  c  subunit 1 (mtDNA  cox 1) sequences and interspecific variations of 0.001–0.081 and 0.196–0.288, respectively, for the small subunit ribosomal DNA (SSU rDNA) and the  cox 1 gene locus. Phylogenetic analyses of pandarid copepods based on sequences available in GenBank plus the sequences generated by our study revealed two major clades: the first, with strong nodal support, included species of  Pandarus ,  Phyllothyreus ,  Pannosus , and  Pseudopandarus ; the second, with weaker nodal support, included species of  Achtheinus ,  Perissopus ,  Echtrogaleus, Nesippus , and  Dinemoura.  As most pandarid species are missing from the present analyses, we discuss the limitations of our phylogenetic results. Nevertheless, this study represents a first step toward to yielding new information about the phylogeny of parasitic copepods on pelagic sharks in the Mediterranean.
