Synergini
inquiline gall wasps
Synergini is a tribe of inquiline gall wasps in the family Cynipidae. Members have lost the ability to induce their own galls and instead inhabit galls created by other cynipid wasps, primarily those in tribe Cynipini. The tribe includes genera such as Synergus, Saphonecrus, Lithosaphonecrus, and Ufo. Most species are associated with oaks (Quercus) and related Fagaceae. A 2015 taxonomic revision transferred three former Synergini genera to other tribes: Ceroptres to its own tribe Ceroptresini, and Periclistus and Synophromorpha to Diastrophini.
