Revision of the New World bee fly genus Heterostylum Macquart (Diptera, Bombyliidae, Bombyliinae)

The genus Heterostylum Macquart and five Neotropical species (H. ferrugineum (Fabricius, 1805), H. hirsutum (Thunberg, 1827), H. rufum (Olivier, 1789), H. haemorrhoicum (Loew, 1863) and H. pallipes Bigot, 1892) are redescribed. The other species, recently redescribed or described are only diagnosed, except for H. deani Painter, 1930, whose spermathecae are described and illustrated for the first time. The main characters of the external morphology were photographed and the male genitalia and female spermathecae illustrated. An identification key to all included species is also presented.
