Two new species of the aorid Amphipoda are described from Chichijima Island, the Ogasawara Islands in Japan. Aoroides macrops sp. nov. from shallow water is characterized by the heavily setose male gnathopod 1, the coxa of which bears several plumose setae anteriorly, and the uropod 2 with a short inter-ramal process. This species is very similar to A. longimerus Ren and Zheng, 1996; however, this new species can be distinguished from A. longimerus by the larger eyes, the shorter carpus of the male gnathopod 1, and the shorter carpi of the pereopods 3 and 4. Grandidierella ogasawarensis sp. nov. from river mouth has the male gnathopod 1 with two teeth on the carpus and an anterodistal projection on the propodus, the male gnathopod 2 with an elongate carpus, and the uropod 1 bearing an inter-ramal process. This new species is different from its closely related congeners (G. koa Barnard, 1977; G. insulae Myers, 1981; and G. rubroantennata Ariyama and Taru, 2017) in the separated teeth on the carpus of the male gnathopod 1.
