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.
基于从日本西南部琉球群岛久米岛附近深水区采集的材料，报道了手螯虾科（Sternostylidae）和真刺螯虾科（Eumunididae）的两个物种，即调查手螯虾（Sternostylus investigatoris，阿尔科克·安德森，1899年）和新物种带纹真刺螯虾（Eumunida balteipes）。调查手螯虾是首次记录，也是该属在日本水域的第二个物种。带纹真刺螯虾新物种在形态上最接近1990年由德·圣洛朗和麦克弗森描述的胸斑真刺螯虾（E. sternomaculata），但第三胸腹板和第一触角柄节的刚毛结构区分了这两个物种。
