Fossil Microgastrinae taxa
Extinct genera and species of Microgastrinae have been found in Eocene and Oligocene deposits, from 37–44 million years ago (MYA). Many specimens from the Miocene (20–30 MYA) are known from Dominican and Chiapas ambers, but most appear to be undescribed representatives of extant genera (Murphy et al. 2008). Belokobylskij (2014) revised the taxonomic status of all previously known taxa of fossil Microgastrinae and described one new genus as well as two new species. The origin of Microgastrinae has been estimated at ~ 54 MYA (Murphy et al. 2008).
Unlike previous work (Mason 1981, Yu et al. 2005, 2012, 2016), Fernandez-Triana et al. (2020) excluded fossil genera or species from the world checklist. Instead, they tabulate in this section the three genera and 12 species of fossil Microgastrinae currently described.
