Comments. Japanagromyza sasakawai is similar to Japanagromyza species that have prescutellar setae and a well-sclerotized tubular aedeagus, but can be differentiated from those by the globose mesophallus with spine-like processes (similar to J. hymenoedemia Sasakawa and J. crinicolis Lonsdale) and the enlarged triangular distiphallus. Larvae form irregular blotches on the surface of the leaf with frass deposited on the edge of the mine.
