Commensal leucothoid amphipods have been collected from the canals of their sponge hosts throughout the Ryukyu Archipelago, Japan. Eleven new species are described in the genus Leucothoe with valuable location data and host records. An identification key to sponge-dwelling Leucothoidae of the Ryukyu Archipelago is provided.

The mitochondrial cytochrome b gene of the Japanese field vole (Microtus montebelli), an herbivorous rodent, was subjected to an analysis of sequence variation with the objective of elucidating the population histories of this species. Construction of a phylogenetic tree revealed the existence of several region-specific lineages in Honshu and Kyushu, which were evenly separated from each other. In consideration of the documented time-dependent evolutionary rates of rodents, the estimated divergence times indicate that the region-specific lineages of M.
