Abstract:
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.
