Two new freshwater species of the genus Jesogammarus (Crustacea: Amphipoda: Anisogammaridae) from northern Japan.
Two new anisogammarid species belonging to the genus Jesogammarus were obtained from freshwater habitats from northern Japan. They are Jesogammarus (J.) fujinoi sp. nov. and Jesogammarus (J.) shonaiensis sp. nov. The former new species is diagnosed by the pleonites without spine and the telson without distolateral spine. The other new species differs from the congeneric species in having many dorsal spines on pleonites 1-3.
