Phylogeny, classification and biogeography of bombyliine bee flies (Diptera, Bombyliidae).

The Bombyliinae comprises over 1100 described species in 73 known genera distributed worldwide. It is one of the largest subfamilies of bee flies (Diptera: Bombyliidae). We present the first phylogenetic hypothesis for this subfamily, based on 157 adult morphological characters scored for 123 species representing 60 genera, including all the tribes of Bombyliinae, and the related subfamilies Lordotinae and Toxophorinae. Four most parsimonious trees were generated from our analysis under equal weighting schemes. The monophyly of Bombyliinae is supported, and Lordotinae is sister to the Bombyliinae. Within Bombyliinae, Conophorini is sister to the remaining tribes. Five previously recognized tribes are revised and four new tribes are erected. We placed almost all genera in our tribal classification, based on our phylogenetic results and available character evidence. The genus Parabombylius is proposed as a synonym of Bombylius. The Gondwanan origin for the major lineages of Bombyliinae is strongly indicated by our biogeographic analysis which reconstructs ancestral areas.
