Andricus is a genus of oak gall wasps in the family Cynipidae.
Cynipini is a tribe of gall wasps. These insects induce galls in plants of the beech and oak family, Fagaceae. They are known commonly as the oak gall wasps. It is the largest cynipid tribe, with about 936 to 1000 recognized species, most of which are associated with oaks. The tribe is mainly native to the Holarctic.
Acraspis is a genus of gall wasps in the family Cynipidae. The following species are recognised in the genus Acraspis:
Trichagalma formosana is a gall wasp species in the family Cynipidae whose life cycle involves only Palaearctic oaks, Quercus subgen. Quercus, in the section Cerris. It is endemic to Taiwan.
Aphelonyx is a genus of oak gall wasps in the family Cynipidae, comprising three known species:
Bassettia is a genus of gall wasps found in North America.
Disholcaspis is a genus of gall wasps in the family Cynipidae. There are more than 40 species described in the genus Disholcaspis. Some Disholcaspis species induce galls that produce honeydew, a sweet liquid that attracts yellow jackets, ants, and bees. These insects then protect the galls from parasitic wasps.
Callirhytis is a genus of gall wasps in the family Cynipidae. There are more than 90 described species in Callirhytis. Wasps in this genus primarily induce wasps on oak trees in North America.
Andricus dimorphus, also called the clustered midrib gall wasp, is a species of oak gall wasp in the family Cynipidae. Galls in which the larvae live and feed are formed in clusters along the midrib on the underside of oak leaves.
Philonix is a genus of oak gall wasps in the family Cynipidae. Species in this genus are only known from Canada, the United States, and Mexico. The larvae of Philonix wasps induce galls on white oaks that are typically spherical, soft and fleshy. Galls are usually formed on the underside of leaves. Adult wasps are similar in appearance to species in the genus Acraspis. Many gall wasps have alternate sexual and asexual generations, but this has not been documented in Philonix.
Amphibolips quercusostensackenii is a species of gall wasp in the family Cynipidae. It is found throughout eastern North America.
Phylloteras is a North American genus of gall wasps in the family Cynipidae, tribe Cynipini .
Druon ignotum is a species of gall wasp in the family Cynipidae.
Burnettweldia is a genus of oak gall wasps in the Nearctic.
Burnettweldia plumbella, also known as the beaked twig gall wasp, is a species of gall wasp. Previously in the genus Disholcaspis, it was moved into a new genus, Burnettweldia, in 2021. This wasp induces galls on oak trees, including blue oak, leather oak, Muller's oak, and scrub oaks. The galls are up to 15 mm in diameter and brightly colored, coming in either red with yellow spots or green with yellow spots. Their name comes from the galls' pointed tip. Galls are formed in spring and summer, and adults emerge from them in November and December. The adult wasps are 3–4 mm in length.
Druon quercuslanigerum is a species of gall wasp that forms galls on Quercus virginiana, Quercus geminata, Quercus fusiformis, and Quercus oleoides. There are both asexual and sexual generations. The asexual generation forms galls on the leaves whereas the sexual generation forms galls on the catkins. It can be found in the southern United States and Mexico. Predators of this species include the green parakeet.
Kokkocynips is an American genus of gall wasps in the family Cynipidae. There are about 8 described species in the genus Kokkocynips with several others still undescribed.
Acraspis guadaloupensis is a relatively uncommon species of cynipid wasp that produces galls on intermediate oaks. The intermediate oak disc wasp was first described in 1911 and has been moved between genera more than once. Distribution is limited to California in North America. The flattened galls appear on leaves of Quercus chrysolepis, the canyon live oak.
Feron is a genus of oak gall wasps in the Nearctic. It was established by Alfred Kinsey in 1937, then re-established in 2023.
Paracraspis is a genus of oak gall wasps in the Nearctic. It was established by Lewis Hart Weld in 1952, then re-established in 2021.
