D. emarginata (Nees, 1834): This species looks very similar to D. maetoi Fernandez-Triana & Shimizu sp. nov. The propodeum and T2 are mostly sculptured, whereas in D. maetoi the propodeum is only sculptured around the areola, and T2 is only sculptured around margins. T1 is slightly thicker in D. emarginata (T1 length 1.4 times its width at posterior margin, whereas in D. maetoi is 1.5–1.7 times). D. emarginata is a solitary parasitoid whereas D. maetoi is gregarious.
