A Review of the Grassflies of the Genus Meromyza Meigen, 1830 (Diptera, Chloropidae) of the Palaearctic Fauna, with a Key to the Species, Analysis of Synonymy, Host Specialization, and Geographical Distribution: Part 1

摘要

The first part of the paper includes a key to 72 Palaearctic and Oriental species of the genus Meromyza. The grass flies of the genus Meromyza Meigen are among the most abundant, species-rich, and widely distributed representatives of the family Chloropidae in the Palaearctic fauna. Larvae of this genus are pests of at least 20 graminean species, including the wheat, rye, and barley (Fedoseeva, 1966, 1969; Hubicka, 1970; Nartshuk, 1972). The genus Meromyza belongs to the subfamily Chloropinae. The species of this genus are characterized by an elongate greenish or yellowish body with black, brownish, or rufous stripes on the mesonotum, except for the only species of the subgenus Nippomera Fedoseeva et Nartshuk with an entirely black body, and also the mostly black M. nigripes Duda.
