Kinorhynchs are marine, microscopic ecdysozoan animals that are found throughout the world's ocean. Cephalorhyncha flosculosa sp. nov. is described from the Aegean Coast of Turkey. Samples were collected from intertidal zones at two localities. The new species is distinguished from its congeners by having flosculi in midventral positions on segment 3-8, and by differences in its general spine and sensory spot positions. Until now, species of Cephalorhyncha were only known from the Pacific Ocean, hence, this record of the genus at the Aegean Sea not only expands its geographic distribution to Turkey, but is likely to expand it throughout the Mediterranean Sea and much of southern Europe. The new species of Cephalorhyncha represents the fifth kinorhynch species recorded from Turkey, and increases also the number of known Cephalorhyncha species to four.
