Adoxophyes fasciata Wlsm., a pest of tea in southern Japan, and A. orana (Fisch. v. Roesl.), which attacks deciduous fruit trees in Japan, have frequently been confused. It has recently been shown that the moths are reproductively isolated. In this first part of a proposed series on the factors isolating the two species [cf. also 62, 4087; 63 2374], the author discusses their distribution in Japan.Only A. orana occurs in Hokkaido and the cooler northern and central montane areas of Honshu, but both species occur sympatrically in the warmer parts of Honshu, Shikoku and Kyushu. Thus, there is no geographical isolation. In the area where they occur sympatrically, there is no evidence of hybridisation, even though their food-plant preferences are such that there is no isolation between their habitats.
