Belonocnema

Belonocnema is a genus of oak gall wasps in the family Cynipidae, found in the United States from Texas, east to Florida. All species induce galls on section Virentes oaks and have both sexual and asexual generations. The asexual generation galls form as small balls on the underside of leaves, and the sexual galls form on roots. A number of inquiline, parasitoid, and hyperparasitoid wasp species have been reared from Belonocnema galls.

Taxonomy
The genus was first named and described by Gustav Mayr in 1881 with Belonocnema treatae as the type species. The taxonomy of the species in the genus has been subject to different interpretations but now appears resolved through study of the morphology, ecology, and genetics of the genus. The genus Dryorhizoxenus, described by William Ashmead, is considered a synonym of Belonocnema, with its type species, D. floridanus, included in B. treatae.

Species
Belonocnema contains the following three species: The current phylogeny of the genus is as follows:
 * Belonocnema fossoria (Weld, 1921)
 * Belonocnema kinseyi (Weld, 1921)
 * Belonocnema treatae (Mayr, 1881)
