Phylogenetic analyses of molecular and morphological data sets for a group of parasitic wasps (Hymenoptera: Braconidae) give strikinglydifferent results.Themoleculardata indicate that the major life history transition fromectoparasitismto endoparasitismhas occurred independently several times within the familywhile the morphological data indicate a single origin. Similar incon- gruent topologies are obtained if the morphological data are partitioned by either of two methods: distinguishing (1) characters of the larval stage and female reproductive system, or (2) characters selected individually by the authors prior to the analysis as likely to be mechanistically associated with endo/ectoparasitism. This result is supported by signi?cant differences in tests of incongru- ence, and we propose that it is caused by convergence among morphological characters resulting froma shared lifehistory strategy.
