Ubristes
''Ubristes'' is a genus of hoverfly, hoverflies, with four known species. All are characterized by their metatibiae, which are usually enlarged, but always with a brush of long pile along the dorsal edges. These flies are probably mimics of the stingless bees in the tribe Meliponini. The presence or absence of the appendix on vein R4+5 is variable within this group. The type species of ''Carreramyia'', ''Hypselosyrphus'' and ''Stipomorpha'' were formerly included in ''Ubristes''; the latter two genera were also considered subgroups of ''Ubristes''. All three are now considered separate genera by Reemer & Ståhls (2013). Biology Larvae are found in ant nests. Distribution They are native to the Neotropical, Neotropics.
