Review of the world species of Exoryza (Hymenoptera, Braconidae, Microgastrinae), with description of five new species

The world species of the genus Exoryza (Hymenoptera, Braconidae, Microgastrinae) are revised. Ten species are recognized, including five new, authored by Fernandez-Triana: mariabustosae, richardashleyi, ritaashleyae, rosamatarritae and yeimycedenoae. The species Dolichogenidea oryzae Walker, 1994 is considered as related to Exoryza - although is not formally transferred to that genus. A dichotomous key to all species, descriptions and illustrations are provided. The only region where the genus is not yet recorded is Australasia, but this may be a collecting artifact. Host caterpillars (Lepidoptera) include species within Choreutidae, Depressariidae, Gelechiidae, and Pyraloidea - all but Pyraloidea are new host records. The status of Exoryza is questioned (it may only represent a species-group within the genus Dolichogenidea) but it is retained as a valid genus until a comprehensive phylogenetic study of Microgastrinae is available.
