Gryon misha Kozlov & Kononova, syn. nov. is considered a junior synonym of G. japonicum (Ashmead). Gryon maruzzae Mineo, syn. nov. and G. sugonjaevi Kozlov & Kononova, syn. nov. are considered junior synonyms of G. yamagishii Mineo. Among the species of the charon-group, G. shisa sp. nov. is newly described. Gryon hakonense (Ashmead) syn. nov. is considered as a junior synonym of G. philippinense (Ashmead). Among the species of the floridanum-group, G. pennsylvanicum (Ashmead) is recognized. Host records of the three species groups are also revised.
