This study verified the host species of the parasitoid Paraganaspis egeria Díaz, Gallardo & Walsh (Hymenoptera: Figitidae: Eucoilinae) in bovine and buffalo dung collected in southern Goias, from January 1998 to June 2004. The pupae were obtained by the flotation method. They were individually placed in gelatin capsules until the emergence of adult flies or their parasitoids. The prevalence of parasitism in cow and buffalo dung was 0.5% and 0.8%, respectively.
