The robber fly information should be considered a work in progress. I am still researching many of these species, and the species descriptions will be refined as I get more information.
The subfamilies are listed in phylogenetic order following Torsten Dikow’s paper Phylogeny of Asilidae inferred from Morphological Characters of Imagines in the Bulletin of the American Museum of Natural History, Number 319, 175 pp., 131 figures, 8 tables. Issued March 17, 2009.
