Asteromyia is a genus of gall midges in the family Cecidomyiidae. There are about nine described species in Asteromyia.
Craneiobia is a genus of gall midges in the family Cecidomyiidae. There are at least two described species in Craneiobia. They create tube-like galls on leaves of Cornus plants.
Ampelomyia vitiscoryloides, the grape filbert gall midge, is a species of gall midge in the family Cecidomyiidae. It induces galls on grape plants and is widespread in eastern North America. It was first described by Alpheus Spring Packard in 1869.
Micromyini is a tribe of wood midges, insects in the family Cecidomyiidae. There are about 9 genera and at least 30 described species in Micromyini.
Asphondylia floccosa, the woolly stem gall midge, is a species of gall midges in the family Cecidomyiidae. The larvae induce galls on Atriplex polycarpa. They don't feed on the gall itself, but rather fungus that grows within the gall. Each gall can contain anywhere from one to fifteen chambers. This species is known from Arizona and California, and was first described by American entomologist Raymond Gagne in 1968.
Lasioptera is a genus of gall midges in the family Cecidomyiidae. There are at least 140 described species in Lasioptera.

Apagodiplosis is a genus of gall midges in the family Cecidomyiidae. There is one described species in Apagodiplosis, A. papyriferae.
Heteropeza is a genus of gall midges and wood midges in the family Cecidomyiidae. There are about six described species in Heteropeza.

Anabremia is a genus of gall midge in the family Cecidomyiidae. The six described species are found in the Palearctic and likely inquilines of Dasineura galls on plants in the legume family. This genus was first described by Jean-Jacques Kieffer in 1912.
