The Figitinae are the primary parasitoids of dipterous larvae. Few studies have been done on this group in Neotropical region. This paper reports a new host and habitat of Neralsia splendens (Borgmeier, 1935) (Hymenoptera: Figitidae). The parasitoid was collected from Oxysarcodexia thornax (Walker, 1849) (Diptera: Sarcophagidae) on traps containing feces humans baits, in Itumbiara, Goias, Brazil, at February 2005. A total of 9 specimens of the parasitoid N. splendens emerged from 50 pupae of O. thornax was collected. The parasitism rate was 18.0 %. This is a new record of the host (O. thornax) and habitat (feces humans) for N. splendens in Brazil.
