  • This study deals with 8 species in 6 genera including 5 new species and 2 new records from Taiwan. The new ones are Neanura kentingensis n.sp., Womersleya formosana n.sp., Crossodinthina montana n.sp., Vitronura tubercula sp., Lobella nana n.sp., and 2 new records are Pseudachorucina nepalica Yosii, 1966 and Lobella perfusa Denis., 1934. The Neanuridae fauna of Taiwan accordingly is listed as 13 species in 7 genera. The biogeographic affinities with the Japan, Vietnam and adjacent countries are discussed.

  • An anisogammarid amphipod, Eogammarus possjeticus (Tzvetkova, 1967), is newly recorded from Jindo Island, Korea, with a detailed description and illustrations. The species belonging to the genus Eogammarus are sharing several plesiomorphic characteristics, so they are similar to each other. However, Eogammarus possjeticus can be discriminated from congeners by the following characters combined: appendages are not fossorial, setations of antennae are weak, and the number and position of robust setae on pleonal epimera, urosomes, and telson are different from its congeners. This is the first record of the genus Eogammarus Birstein, 1933 from Korean waters.

  • Jesogammarus (Jesogammarus) hinumensis Morino, 1993 was discovered firstly from a brackish water region in Jeju Island, Korea. To identification of the specimens we conducted both of morphological and molecular analyses. This species is characterized by having large eyes and a robust seta on the mandibular palp article 1. The morphology of this Korean specimens was well matched with the original description without variation. The mitochondrial cytochrome c oxidase subunit I(COI) sequences of the present specimens were also completely identical to the sequences of J. (J.) hinumensis collected from the type locality of the species. Thus, we concluded that the Jesogammarus species from Jeju Island is J.(J.) hinumensis, based on both morphological and molecular data.
