Records of Hippoboscidae, Nycteribiidae and Streblidae (Diptera) from Japan

Records of Hippoboscidae, Nycteribiidae and Streblidae collected in Japan were presented. Data for localities, dates, collectors were given for all the specimens examined. The following seven species were recorded from Japan for the first time with an undescribed Phthiridium sp.; Ornithomya comosa, Ornithomya fuscipennis, Icosta holoptera omnisetosa, Icosta maquilingensis, Icosta sensilis sensilis, Nycteribia pleuralis, Nycteribia uenoi. Total numbers of species recorded from Japan count 26 for Hippoboscidae, 11 for Nycteribiidae and 4 for Streblidae. All the species recorded from Japan were tabulated with summarized information about hosts and distribution in Japan for each species. Host preference and geographical distribution of bat flies in Japan have become rather clear but information for species of Hippoboscidae is still fragmentary.
