Studies on the species of Fanniinae (Diptera : Muscidae) from Japan. II. : One new species from Japan and Taiwan, and four newly recorded species of genus Fannia from Japan

One new species of genus Fannia is described from Japan (Honshu and Amami-Oshima Is.) and Taiwan. It is difficult to determine the status of the species-group. Regarded from the genitalic structure the present species seems to belong to the pretiosa group, and to be closely allied to Fannia horii Kurahashi and F. tunisiae Chillcott. Fannia coracula Collin, F. mollissima (Haliday), F. nigra Malloch and F. vesparia (Meade) are newly recorded from Japan. European F. nigra has not hairs on posterior inner margin of hind coxa, but some of the Japanese specimens have setulae on hind coxae. Although this character is very important in the identification of the genus Fannia, it is not so substantial in F. nigra.
