Nine new species of Itaplectops Townsend (Diptera: Tachinidae) are described from Area de Conservación Guanacaste (ACG), northwestern Costa Rica. All specimens have been reared from ­various species of ACG caterpillars in the families Limacodidae and Dalceridae. By combining morphological, photographic, and genetic barcode data we provide clear yet concise descriptions. The following nine new species are described in the genus Itaplectops: Itaplectops akselpalolai, Itaplectops anikenpalolae, Itaplectops argentifrons, Itaplectops aurifrons, Itaplectops ericpalolai, Itaplectops griseobasis, Itaplectops omissus, Itaplectops shellymcsweeneyae, Itaplectops tristanpalolai. We move Itaplectops to the tribe Uramyini from its original placement within the Blondeliini, and we discuss its systematic placement. We also provide a key differentiating the, genera of the tribe Uramyini as well as the known species of Itaplectops.
