Abstract
Male and female of Odaginiceps korykosensissp. n. (Copepoda, Harpacticoida, Tetragonicipitidae), collected in the intertidal zone of Kızkalesi beach along the Mediterranean coast of Turkey (Mersin Province), are described. The new species is the fifth member of the genus and can easily be distinguished from the other species by the presence of four setae/spines on the second endopodal segment of P4 and by the structure of the caudal rami. Previously, representatives of the genus Odaginiceps have been reported from Gulf of Mexico, off Bermuda and Kenya. Odaginiceps korykosensissp. n. is the first record of the genus in the Mediterranean Sea.
