Phylogeny and taxonomic revision of the genus Eristalopsis Evenhuis (Diptera: Bombyliidae: Bombyliinae)

The endemic Australian bee fly genus Eristalopsis Evenhuis, 1985 (Bombyliidae: Bombyliinae) is reviewed including 11 new species: E. aurata sp.n., E. concava sp.n., E. danielsorum sp.n., E. flava sp.n., E. maculata sp.n., E. minor sp.n., E. parva sp.n., E. rubra sp.n., E. smarti sp.n., E. uniformis sp.n., E. wrightae sp.n. In addition, we generate a morphological phylogeny including all recognised species. This genus can easily be distinguished from other Australian genera in the subfamily Bombyliinae by having a 2-segmented antennal flagellum, cell br longer than cell bm, crossvein m-m in apical half of cell dm, crossvein r-m much longer than crossvein m-m, abdominal tergites with black and yellow pattern, and female genitalia without sand chamber. A key to species of Eristalopsis is provided.
