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. [1] [2] A number of inquiline, parasitoid, and hyperparasitoid wasp species have been reared from Belonocnema galls. [2]
The genus was first named and described by Gustav Mayr in 1881 with Belonocnema treatae as the type species. [1] [3] 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. [1] The genus Dryorhizoxenus, described by William Ashmead, is considered a synonym of Belonocnema, with its type species, D. floridanus, included in B. treatae. [1] [4]
Belonocnema contains the following three species: [1]
The current phylogeny of the genus is as follows: [1]

Gall wasps, also traditionally calledgallflies, are hymenopterans of the family Cynipidae in the wasp superfamily Cynipoidea. Their common name comes from the galls they induce on plants for larval development. About 1,300 species of this generally very small creature are known worldwide, with about 360 species of 36 different genera in Europe and some 800 species in North America.
Neuroterus is a genus of gall wasps that induce galls on oaks in which the wasp larvae live and feed. Some species produce galls that fall off the host plant and 'jump' along the ground due to the movement of the larvae within.
Galeopsomyia is a New World genus of hymenopteran insects of the family Eulophidae. The genus is a hyperparasitoid of other gall-inducing wasps of the genera Eurytoma and Torymus.
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.
Andricus quercuscalifornicus, or the California gall wasp, is a small wasp species that induces oak apple galls on white oaks, primarily the valley oak but also other species such as Quercus berberidifolia. The California gall wasp is considered an ecosystem engineer, capable of manipulating the growth of galls for their own development. It is found from Washington, Oregon, and California to northern regions of Mexico. Often multiple wasps in different life stages occupy the same gall. The induced galls help establish complex insect communities, promoting the diversification in niche differentiation. Furthermore, the adaptive value of these galls could be attributed their ecological benefits such as nutrition, provision of microenvironment, and enemy avoidance.
Bassettia is a genus of gall wasps found in North America.
Bassettia pallida is a species of gall wasp found in the Southern United States. This species was described by American entomologist William Harris Ashmead in 1896. B. pallida reproduces asexually in galls it induces on oak trees. The parasite Euderus set, a eulophid wasp, has B. pallida as a host and manipulates its behavior.
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.
Synergus japonicus is a species of gall wasp in the family Cynipidae. Whereas most gall wasps create the galls in which they live, Synergus japonicus is an inquiline species, living in the gall created by another species of wasp. It is native to Japan, China and Russia.
Andricus quercuspetiolicola, also called the oak petiole gall wasp, is a species of oak gall wasp in the family Cynipidae. Galls in which the larvae live and feed are formed along the midrib or petiole of white 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.
Disholcaspis quercusmamma, the oak rough bulletgall wasp, is a species of gall wasp in the family Cynipidae. The quercus in its name is the genus name for oak, while "mamma" is Latin for "breast", presumably a reference to the "nipple" on the gall.
Phylloteras volutellae, the conical oak gall wasp, is a species of gall wasp , tribe Cynipini , found in North America.
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.
Belonocnema treatae is a species of gall wasp that forms galls on Quercus virginiana and very rarely Querucs geminata. There are both asexual and sexual generations. The asexual generation forms galls on the underside of leaves whereas the sexual generation form galls on the roots. It can be found in the United States, where it is known from Alabama, Florida, Georgia, Mississippi, North Carolina, South Carolina. It, along with the other described Belonocnema species, have been used to study speciation.
Belonocnema kinseyi is a species of gall wasp that forms galls on Quercus virginiana and Quercus fusiformis. There are both asexual and sexual generations. The asexual generation forms galls on the underside of leaves whereas the sexual generation form galls on the roots. It can be found in the United States, where it is known from Louisiana, Mississippi, Oklahoma and Texas. It, along with the other described Belonocnema species, have been used to study speciation.
Belonocnema fossoria is a species of gall wasp that forms galls on Quercus geminata. There are both asexual and sexual generations. The asexual generation forms galls on the underside of leaves whereas the sexual generation form galls on the roots. It can be found in the United States, where it is known from Georgia and Florida. It, along with the other described Belonocnema species, have been used to study speciation.
