Cynips is a genus of gall wasps in the tribe Cynipini, the oak gall wasps. One of the best known is the common oak gall wasp, which induces characteristic spherical galls about two centimeters wide on the undersides of oak leaves.
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. Cynipini wasps can act as ecosystem engineers. Their galls can become hosts of inquilines, and the wasps themselves are hosts to parasitoids.
Pseudoneuroterus nichollsi is a gall wasp species in the family Cynipidae whose life cycle involves only Palaearctic oaks, Quercus subgen. Quercus, in the section Cerris.
Pseudoneuroterus mazandarani is a gall wasp species in the family Cynipidae whose life cycle involves only Palaearctic oaks, Quercus subgen. Quercus, in the section Cerris. The species is named for the Mazandaran province of Iran where it was collected. Gall wasps evolved in the Northern Hemisphere and started as herb gallers. Through natural selection they went through a period where they lost the ability to initiate galls and later regained it back. It is suggested the first gall wasps were associated with woody host plants.
Dryocosmus jungalii is a gall wasp species in the family Cynipidae whose life cycle involves only Palaearctic oaks, Quercus subgen. Quercus, in the section Cerris.
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 kordestanica is a gall wasp species in the family Cynipidae whose life cycle involves only Palaearctic oaks, Quercus subgen. Quercus, in the section Cerris.
Aphelonyx is a genus of oak gall wasps in the family Cynipidae, comprising three known species:
Synergini is a tribe of gall wasps in the subfamily Cynipinae.
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.
Acraspis quercushirta, the jewel oak gall wasp, is a species of gall wasp in the family Cynipidae, tribe Cynipini, found in North America.
Druon is a genus of gall wasps in the family Cynipidae. The type species is Druon protagion. Recognised species include:
Druon ignotum is a species of gall wasp in the family Cynipidae.
Druon fullawayi, also known as the yellow wig gall wasp, is a species of gall wasp in the family Cynipidae. It was previously placed in the genus Andricus. William Beutenmüller described the female adult wasps as 1.5-2.25 mm long, black with brown mouth parts and brown legs. The galls of D. fullawayi are tan or yellow, woolly, and measure 5-8 mm in diameter. Each gall holds a single chamber for larvae. They are found in California on oak trees, especially Quercus lobata.
Burnettweldia is a genus of oak gall wasps in the Nearctic.
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.
Besbicus is a genus of gall-inducing cynipid wasp found in North America. Several species now classed as Besbicus were formerly considered to be a part of the genus Cynips. Besbicus was originally described as a subgenus by Alfred Kinsey in 1929. Circa 2010, one group of entomologists noted that it was "possible that the nearctic genera Antron and Besbicus were erroneously synonymized to Cynips".
