Abstract
The phylogeny of the parasitic wasp family Orussidae is analyzed with a slightly expanded version of a previously published data set. The basal splitting events in the family between two fossil taxa and the extant members are not unambiguously resolved. Intergeneric relationships in general are poorly supported and change under different analytical conditions. This corroborates earlier findings regarding the phylogeny of the family. A resumé of the evolutionary history of the Orussidae is provided. Leptorussus madagascarensis sp.n. is described.
