A revision of Dolichogenidea (Hymenoptera, Braconidae, Microgastrinae) with the second mediotergite broadly rectangular from Area de Conservación Guanacaste, Costa Rica.

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.
