Discussion. The distribution of this species in the Oriental Region, Australian Region, Nearctic Region and Palaearctic Region. Th is species, first described from the USA (Osborn, 1900), is apparently native to Japan (Sanders and DeLong, 1920), from which it was introduced to North America with nursery stock of Japanese maples. It was subsequently (Matsumura, 1914) also described from Japan. It’s a known host plants are maples, other plants have not collected this specimen. Th is species in western Europe seems to be confined to parks where ‘Japanese maples’ ( Acer palmatum) are planted. Th e distribution of this species may be related to its host plants.

Known hosts. Maple, Aceraceae ( Acer palmatum, Acer buergerianum, Acer truncatum).
