The aim of this study is to report the first occurrence of the parasitoid Triplasta coxalis (Ashmead, 1865) (Hymenoptera: Figitidae: Eucoilinae) in pupae of Archisepsis scabra (Loew, 1861) (Diptera: Sepsidae) in cattle dung in Brazil. The experiment was carried out in Monte Alegre, MG. One obtained the pupae through the flotation method. They were individually placed in gelatin capsules until the emergence of the adult dipterous or their parasitoids. Fourty seven pupae of A. scabra were obtained, two of which yielded the parasitoid T. coxalis. The percentage of parasitism was 4.3%.
