 note = {Thesis, Only a few studies on the morphological characteristics of female genitalia of tabanids are found in the past 60 years. And no reports about the tabanids inhabiting Hokkaido can be seen in this respect. In this study, I reported the main features of female genitalia of some tabanids of Hokkaido, Japan. I examined 24 species out of 3 subfamilies and 6 genera of tabanids of Hokkaido. The examined parts are tergite 9, tergite 10, cercus, sternite 8, spermathecae, spermathecal duct and genital fork. The results show that: both right and left tergite 9 of species of the subfamily Pangoniinae tied each other, but those of the species of the subfamily Tabaninae and Chrysopsinae are not connected; the shape is roughly triangular in the subfamily Pangoniinae and Tabaninae and Chrysops vonderwulpi, and those of the subfamily Chrysopsinae are crescent shape. In the subfamily Chrysopsinae, tergite 10 is triangular shape tapering outward; the other two subfamilies are not like that. Sternite 8 of the subfamily Tabaninae is star-like, and those of the subfamily Chrysopsinae and Pangoniinae are like vats and hexagon. Spermathecae of the subfamily Pangoniinae is circle, but stout and big in the subfamily Chrysopsinae, and the subfamily Tabaninae, except of band shaped Tabanus fulvimediodes, spermathecae is fusiform. Spermathecal duct of the subfamily Chrysopsinae is comparatively short and stout at apical part, and at the base is slender, but that of the subfamily Tabaninae is comparatively long, except Tabanus kinoshitai; species of the subfamily Tabaninae have a mushroom-shaped expansion at the end, but no expansion is seen in the subfamily Chrysopsinae and Pangoniinae. Membranes of genital fork of the subfamily Tabaninae are fan-shaped or crescent shape, but in the subfamily Chrysopsinae and Pangoniinae, it is peltate. These are the differences of subfamily level. To the genus and species level classification, to combine the characteristics of tergite 9, tergite 10, cercus, sternite 8, spermathecae, spermathecal duct and genital fork is required.},
