6th International Congress of DipterologyA molecular phylogeny of the AsiloideaWiegmann, B.M. (1), M.D. Trautwein (1) & D.K.

Relationships among the asiloid families havebeen controversial or poorly resolved due to differing interpretations ofmorphological character evolution and a general lack of definitivecharacters. In the current study, we combine data from multiple genes,including CAD and the 28S ribosomal RNA gene (28S rDNA), for 50 taxarepresenting all asiloid families. Parsimony and Bayesian likelihoodanalyses provide support for the monophyly of the superfamily and for itsconstituent families. Molecular evidence for the position of enigmatic taxa,including Hilarimorphidae, Evocoidae, and Apystomyia are also discussedin light of newly emerging morphological data.Key Words: Asiloidea, molecular systematics, phylogeny, Brachycera∗∗∗∗∗∗∗∗∗∗300
