| Abstract;Parhyale hachijoensis sp. nov., from the Izu Islands of Japan, is characterized by the following features: in maxilla 1 the palp is 2-articulate with the articulation near the middle of the palp; in gnathopod 1 one of the palmar corner spines on the propodus is displaced to the posterior margin; in pereopods 6 and 7 the posterior margins of the propodi are lined with 4 and 3 groups of spines, respectively; in uropod 1 the peduncle has an ordinary distolateral spine; and in uropod 3 the inner ramus is vestigial and fused to the peduncle. Parhyale philippinensis sp. nov., from two sites in the Philippines, is characterized by the following features: in maxilla 1 the palp is 1-articulate with a constriction slightly beyond the middle of the palp; in gnathopod 1 the palmar corner spines of the propodus are close together; in pereopods 6 and 7 the posterior margins of the propodi are lined with 5 groups of spines; in uropod 1 the peduncle has an elongate distolateral spine; and in uropod 3 the inner ramus is fully articulated. The fact that both new species have the propodal posterior margins lined with a number of groups of spines in pereopods 6 and 7 suggests that they belong to the P. hawaiensis complex.
