Abstract

Two new species of bogidiellid amphipods, Bogidiella isajii and B. painushima are described from an anchialine undersea cave in Minamidaito Island and freshwater flowing through a cave in Ishigaki Island, Ryukyu Islands. Bogidiella isajii sp. nov. differs from its congeners in the absence of an inner ramus on the pleopods, armature of uropods 1 and 2 rami, and shape of the telson. Bogidiella painushima sp. nov. is morphologically similar to B. aprutina and B. broodbakkeri, but differs from these two species in the shape of antennal sinus of the head, size of antenna 2 peduncular article 2 gland cone, armature of the accessory setal row of the mandible, shape of gnathopod 1 propodus and pereopod 7 coxa, and armature of the telson. Nucleotide sequences of the mitochondrial cytochrome c oxidase subunit I from paratypes of the two new species were determined for future studies.
