Chrysonotomyia

Chrysonotomyia is a genus of small parasitoid wasps in the family Eulophidae, with over 170 described species. Members of the genus tend to attack insect larvae that feed within living plant tissue, such as gall-formers, leaf-miners and stem-miners. The Neotropics contain most described species. Within the region, most attack galls induced by Cecidomyiidae midges, although there are also records from Torymidae galls, Cynipidae galls, Psyllidae galls, Momphidae leaf mines and scale insects in the family Coccidae.

Chrysonotomyia species can be recognized by the following combination of characteristics: clypeus delimited on the sides only, postmarginal vein usually shorter than stigmal vein (although it is longer in some species), midlobe of mesoscutum with one pair of hairs (2-3 in some species), notauli poorly delimited or missing, and the flagellum with L-shaped peg sensilla.
