Euphorinae

Guides

Aridelus
Aridelus is a genus of braconid wasps in the subfamily Euphorinae, comprising approximately 40 described species with cosmopolitan distribution but greatest diversity in tropical regions. These wasps are solitary koinobiont endoparasitoids of heteropteran bugs, primarily targeting nymphs and adults of stink bugs (Pentatomidae) and related families. Several species have been investigated for biological control potential against agricultural pests, particularly Nezara viridula.

Cryptoxilos
Cryptoxilos is a genus of parasitoid wasps in the family Braconidae, subfamily Euphorinae, established by Henry Lorenz Viereck in 1911 with C. dichromorphus as the type species. The genus contains eight described species distributed across multiple continents. Members are known to parasitize adult bark beetles (Scolytinae, Coleoptera), with documented associations including Chaetoptelius mundulus in New Zealand and Hypothenemus species in Fiji.

Elasmosoma
Elasmosoma is a small genus of ant-parasitoid wasps in the family Braconidae, subfamily Euphorinae, tribe Neoneurini. Species are minute, typically under 2.0 mm in length, and are specialized endoparasites of adult Formicidae ants. Females attack host workers in flight, alighting briefly to oviposit into the abdomen. The genus comprises approximately 13 described species distributed across the Northern Hemisphere, with records from Europe, Asia, and North America. The host-parasite association represents a well-balanced system that has persisted for at least 40 million years.

Elasmosoma michaeli
Elasmosoma michaeli is a species of parasitoid wasp in the family Braconidae, described by Shaw in 2007. It belongs to a genus of small wasps that attack ants. The genus Elasmosoma is part of the subfamily Euphorinae, tribe Neoneurini, which are specialized ant parasitoids.

Elasmosoma schwarzi
Elasmosoma schwarzi is a species of parasitoid wasp in the family Braconidae, subfamily Euphorinae, described by Ashmead in 1895. The genus Elasmosoma comprises ant parasitoids, with females depositing eggs inside adult ant workers. E. schwarzi is native to the southwestern United States, where it has been documented in Texas. Like other members of the genus, it exhibits specialized adaptations for attacking ants, which are highly defensive hosts.

Leiophron
Leiophron is a genus of endoparasitoid wasps in the family Braconidae, subfamily Euphorinae. Species are known to parasitize plant bugs (Miridae), particularly nymphal and adult stages of Lygus species and related mirids. The genus has been taxonomically reviewed for Nearctic species, with multiple new species described and synonymies established. Leiophron species show distinct host associations and geographic distribution patterns, with documented occurrence in the Nearctic, Palaearctic, and Old World tropics.

Microctonus
Microctonus is a genus of braconid parasitoid wasps in the subfamily Euphorinae. Species are endoparasitoids of adult beetles, primarily targeting weevils (Curculionidae) and flea beetles (Chrysomelidae). The genus contains approximately 31 species in North America and additional species globally, including several used as classical biological control agents. Notable biocontrol species include M. aethiopoides and M. hyperodae, introduced to New Zealand to control forage pests, and M. aethiops and M. vittatae, used in North American agricultural systems. Many species exhibit parthenogenetic reproduction, with M. hyperodae showing arrhenotokous parthenogenesis (males produced parthenogenetically).

Microctonus pilatus
Microctonus pilatus is a species of parasitoid wasp in the family Braconidae, subfamily Euphorinae. Members of this genus are known as parasitoids of adult beetles, particularly weevils (Curculionidae). The species was described within the genus Microctonus, which has been subject to taxonomic revision and includes species used in biological control programs. Specific details about M. pilatus itself remain limited in published literature.

Neoneurini
Neoneurini is a tribe of braconid wasps in the subfamily Euphorinae, historically treated as a separate subfamily but now placed within Euphorinae based on molecular data. The tribe contains three European genera—Elasmosoma, Kollasmosoma, and Neoneurus—comprising koinobiont endoparasitoids of adult ants. These wasps possess highly specialized morphological adaptations for attacking ants, including a strongly curved, hook-shaped ovipositor directed forward, and modified legs with vestigial tarsal claws and enlarged pulvilli for grasping ant metasomas. The tribe has a fossil record extending to Baltic amber.

Neoneurus
Neoneurus is a genus of minute parasitoid wasps in the family Braconidae, tribe Neoneurini. These wasps are specialized ant parasitoids, with females attacking adult ant workers in flight to deposit their eggs. The genus includes species such as Neoneurus vesculus, which has been filmed ovipositing into Formica cunicularia workers. Neoneurus species are among the few parasitoids capable of overcoming ant defenses, representing a highly specialized ecological adaptation.

Syntretini
Syntretini is a tribe of parasitic wasps within the subfamily Euphorinae (family Braconidae). Members of this tribe are endoparasitoids, with known hosts including adult beetles (Coleoptera) and possibly other insects. The tribe has been subject to phylogenetic study to clarify its relationships within Euphorinae and evolution of host associations.

Zele
Zele is a genus of braconid parasitoid wasps in the subfamily Euphorinae, containing approximately 30 species worldwide. The genus is distinguished by specific wing venation features: presence of vein r-m on the fore wing, a rhomboid or quadrate second submarginal cell of the fore wing, and an apically widened marginal cell on the hind wing. Species are koinobiont endoparasitoids of lepidopteran larvae. The genus is widespread across the Palearctic, Nearctic, and Oriental regions but absent from the Afrotropical and Australian regions.
