year. The larvae of both the gall-inducing Diplolepis species and the inquilines (if present) are used as hosts by a number of parasitoid wasps, including wasps from the families Eulophidae, Eurytomidae, Chalcididae, Pteromalidae, Torymidae, and Ichneumonidae. Taxonomy The name 'Diplolepis' was first used for this group by Etienne-Louis Geoffroy in 1762. The genus is monophyletic and, with Liebelia, constitutes the tribe Diplolepidini within the subfamily Cyinipinae. There are currently about 50 described species in the genus, including: Diplolepis abei Diplolepis arefacta Diplolepis ashmeadi Diplolepis bassetti Diplolepis bicolor Diplolepis californica Diplolepis dichlocera Diplolepis eglanteriae Diplolepis flaviabdomenis Diplolepis fructuum Diplolepis fulgens Diplolepis fusiformans Diplolepis gracilis Diplolepis hunanensis Diplolepis ignota Diplolepis inconspicuis Diplolepis japonica Diplolepis lens Diplolepis mayri Diplolepis minoriabdomenis Diplolepis nebulosa Diplolepis neglecta Diplolepis nervosa Diplolepis nigriceps Diplolepis nitida Diplolepis nodulosa Diplolepis oregonensis Diplolepis ostensackeni Diplolepis polita Diplolepis pustulatoides Diplolepis radicum Diplolepis radoszkowskii Diplolepis rosae Diplolepis rosaefolii Diplolepis similis Diplolepis spinosa Diplolepis spinosissimae Diplolepis terrigena Diplolepis triforma Diplolepis tuberculatrix Diplolepis tumida Diplolepis valtonyci Diplolepis variabilis Diplolepis variegata Diplolepis verna Diplolepis weldi References Cynipidae Hymenoptera genera Taxa named by Étienne Louis Geoffroy
