Abstract

Revision of the genus Meromyza Mg. (Diptera: Chloropidae) in Japan, with three newly recorded species.

Abstract

Only 2 species of Meromyza had previously been recorded from Japan: M. nipponensis Nishijima, which develops on the young shoots of Sasa kurilensis and is not of economic importance, and M. saltatrix (L.), known as a pest of small-grain cereal crops. Studies have shown that specimens from Japan that have been attributed to M. saltatrix consist of 2 distinct species: M. nigriventris Macq., which occurs on cereal crops in Hokkaido, and M. orientalis Fedoseeva, which occurs in Hokkaido, Honshu and Kyushu and is usually associated with wild plants, though it occasionally attacks wheat in northern Honshu. Three other species of Meromyza are recorded for the first time from Japan. They are M. sibirica Fedoseeva, M. inornata Becker and M. pratorum Mg. A key is provided for the separation of adults of these 6 species.
