Abstract:
The first species of Dolichogenidea (Hymenoptera: Braconidae, Microgastrinae) with the second mediotergite
broadly quadrate to rectangular are revised, and eight new species from Area de Conservación Guanacaste
(ACG), Costa Rica are described, all authored by Fernandez-Triana & Boudreault: alejandromasisi,
angelagonzalezae, carlosmanuelrodriguezi, genuarnunezi, josealfredohernandezi, melaniamunozae, rogerblancoi,
and yeimycedenoae. A new species group (carlosmanuelrodriguezi) within the genus is proposed to accommodate
those species, as well as additional undescribed species from the Neotropical region found in
collections. All new species are found in rainforests (120–900 m) and all are parasitoids of Depressariidae
(except for one species parasitizing Choreutidae). The unique shape of the second mediotergite and long
ovipositor are features shared with the alejandromorai species group in the genus Apanteles, an example of
convergent evolution; both wasp groups also parasitize similar hosts in ACG.
