Ceroptresini
Ceroptresini is a tribe of inquiline gall wasps in the family Cynipidae, containing two genera: Ceroptres (with 43 species) and Buffingtonella (with one species). First established as a tribe in 2015, these wasps are predominantly found in North America, though some species occur in the Eastern Palearctic and Oriental regions. Members of this tribe do not induce their own galls but instead inhabit galls created by other cynipid wasps, primarily on oaks (Quercus spp.), with some species reared from cecidomyiid midge galls.
Periclistus
Periclistus is a genus of micro-hymenopteran gall wasps (Cynipidae) comprising at least 17 described species. These wasps are obligate inquilines that occupy galls induced by other cynipid genera on plants in the rose family (Rosaceae), particularly roses (Rosa). Unlike gall inducers, Periclistus species have lost the ability to initiate galls but retain the capacity to modify existing gall tissue, inducing nutritive tissue for their own larvae. The genus exhibits a phylogenetic divide between Palaearctic and Nearctic clades, with host specificity ranging from specialists to generalists across different species.
