With an estimated 150,000 described species, the insect order Diptera (true flies), is one of the most diverse branches on the Tree of Life. Although the family Therevidae occupies only a relatively small portion of that tree, our study of the family combines revisionary taxonomic work with morphological and molecular phylogenetic data collection to assess relationships within the family, and among its closest relatives.

Find out what phylogeny is and something about the world of phylogenetic systematics.
