The aim of this study was to report the insect species parasitizing Fannia pusio (Wiedemann, 1830) (Diptera: Fanniidae), in Caldas Novas, State of Goiás, between August 2003 and May 2004. Flies were attracted to baits consisting of human feces, bovine liver and fish, with the pupae being isolated by the flotation method, in water, and individually placed in gelatin capsules until the emergence of the flies and/or their parasitoids. The parasitism percentages presented by Pachycrepoideus vindemmiae (Rondani, 1875) (Hymenoptera: Pteromalidae), Spalangia nigra Latrielle, 1805 (Hymenoptera: Pteromalidae), Paraganaspis egeria Díaz, Gallardo & Walsh, 1996 (Hymenoptera: Figitidae) and Spalangia drosophilae Ashmead, 1887 (Hymenoptera: Pteromalidae) were 4.3, 1.5, 0.9 and 0.6%, respectively. The total percentage of parasitism was 7.4%. This study reports the first occurrence of S. nigra in pupae of F. pusio in Brazil.
