Synonyms and other taxonomic changes

Synerginae Ashmead, 1896
"The tribe Synergini, which used to include all the familiar Northern Hemisphere inquilines, is narrowed down here to include only the inquilines associated with Fagaceae, plus the afrotropical Rhoophilus, which is an inquiline in galls on Rhus. There is strong molecular evidence for the monophyly of this clade. The genus Ceroptres is moved to its own tribe, while Periclistus and Synophromorpha are transferred to the tribe Diastrophini." (1)

Numbers

8 genera (Agastoroxenia, Lithonecrus, Lithosaphonecrus, Rhoophilus, Saphonecrus, Synophrus, Synergus, Ufo); about 180 species worldwide (1)

Remarks

Inquilines (rarely true gall inducers) in cynipid galls on several Fagaceae genera, mainly Quercus (1).
