  • ABSTRACT

    Parartotrogus minutus n. sp. is described as a parasite of the brittle star Ophiuroglypha kinbergi (Ljungman) from the intertidal zone on the Yellow Sea coast of Korea. The new species is characterized by a combination of morphological features that the body is small, less than 0.5 mm long, the caudal ramus is 1.73 times longer than wide, leg 3 bears three-segmented rami, and the exopod of leg 5 is armed with two setae. The new species is the third known species in the genus, following P. richardi Scott T. and Scott, A., 1893 known from European waters and P. arcticus Scott T., 1901 known from both North Atlantic and North Pacific.
