Triplasta coxalis (Ashmeda) (Figitidae: Eucoilinae), was found as a parasitoid of Palaeosepsis sp. (Diptera: Sepsidae) in Itumbiara, GO, Brazil (18º25'S and 49º13'W). The samples of bovine dung were taken from pats 24, 36, 72, 96, 120, 144, 168, 192, 216, and 240 hours of exposition, placed in plastic containers and kept in the laboratory conditions. The pupae were extracted by flotation in water. Pupae were individually placed in gelatin capsules until emergence of adult flies or their parasitoids. Four and one specimens of Triplasta coxalis and Kleidotoma nigra, respectively, were collected. This was the first report on occurrence of the parasitoid Kleidotoma nigra and Triplasta coxalis in Goiás.
