Abstract
Two species of the chirostyloid families Sternostylidae and Eumunididae, Sternostylus investigatoris (Alcock & Anderson, 1899) and Eumunida balteipes n. sp., are reported on the basis of material collected from deep waters off Kume Island, Ryukyu Islands, southwestern Japan. Sternostylus investigatoris is recorded for the first time and is the second species of the genus from Japanese waters. Eumunida balteipes n. sp. is morphologically closest to E. sternomaculata de Saint Laurent & Macpherson, 1990, but the armature of the thoracic sternite 3 and P1 palm distinguishes the two species.
