Synonyms and other taxonomic changes
Traditionally treated as a subfamily of Bombyliidae; there is no consensus among experts about the status of this group.
>170 spp. (of which 160 in Mythicomyia) in 3 genera in our area(1), ~350 spp. in 25 genera worldwide(2)
Similar to Bombyliidae but the adult thorax is with bristles not strongly developed, bristles on legs other than apical bristles lacking, cells br and bm usually equal in length or nearly so, vein R2+3 absent or short, ending in R1, and R4+5 unbranched, R5 absent.
Larvae of Mythicomyia are known as gregarious parasites of solitary bees; Glabellula are possible predators (free-living or inhabiting ant nests); the exotic Psiloderoides prey on grasshopper egg pods(3).
Fossil record is 200 million years older than the oldest bombyliid fossil(3).
