Genera

The following genera are generally accepted within Synergini:^[3]

• Agastoroxenia^[4]
• Lithosaphonecrus^[5]
• Saphonecrus
• Rhoophilus^[6]
• Synergus
• Ufo

All of these except Lithosaphonecrus and Rhoophilus are found in the eastern Palearctic realm.^[3] Synergus has the greatest number of species in Synergini.^[6]

A reworking of the entire Cynipidae family published in 2015 transferred three genera formerly included in Synergini to other tribes - Ceroptres to a tribe of its own (Ceroptresini), and Periclistus and Synophromorpha to Diastrophini.^[7]

Gall use

Members of Synergini have lost the ability to create their own galls, and instead make use of galls left behind by other wasps. As a result, they are classified as inquilines.^[8] Species in Synergini usually make use of galls made by wasps in tribe Cynipini.^[6]
