Extant species of sciadocerid flies are restricted to wet forests in the Southern Hemisphere. Only one true sciadocerid fossil, Archiphora robusta Meunier from Baltic amber, is currently known.
McAlpine & Martin (1966) published a work on Sciadoceridae from the Upper Cretaceous of Canada and described two new genera as belonging to this family. Hong (1981) described a third putative sciadocerid fossil. However, subsequent work showed that these three genera actually belong to the Phoridae.
