Genus Akatiomyia gen. n.

Etymology: From Greek ΑΚΆΤΙΟν (a dwarf) and μΥΙΑ (a fly). Refers to small size of this robber fly.

Type species: Akatiomyia eremnos sp. n.

Diagnosis: Tiny flies (wing length <5 mm). Head: Clearly wider than high in anterior view; antennal scape longer than pedicel; postpedicel greatly elongate (c. twice the length of scape and pedicel combined), cylindrical (not widening toward the middle) and with distinct well-developed style; style with numerous, short, tightly packed setae (not longish, loosely arranged setae as in Oligopogon ); face narrower than width of one eye in anterior view; facial swelling weak and not well-defined dorsally; mystax occupying about half of facial profile; occiput with macrosetae; palpus 2-segmented; proboscis shorter than antenna, straight and without spine-like processes distally. Thorax: Prosternum small and isolated (not large and abutting pronotum as in Oligopogon ); propleuron fine setose; mesonotum flat (not greatly elevated and hump-like as in Oxynoton Janssens, 1951 and some Oligopogon ) and punctate; acrostichal, dorsocentral, postpronotal and postalar macrosetae undifferentiated; scutellum lacking apical macrosetae; scutellar disc setose; anepimeral macroseta absent; katatergite setose; anatergites asetose; postmetacoxal area membranous; prothoracic femora slender; mesothoracic tarsomeres 4 and 5 without modified setae (as in Habropogon Loew, 1847 ); pulvilli well developed; metathoracic empodia simple (not large and laterally compressed as in Empodiodes Oldroyd, 1972 ); costa extends only as far as CuA 1 (not bordering anterior cubital cell, anal cell and alula); cell m 3 open; cell cup closed and stalked. Abdomen: Tergites punctate; female with acanthophorites.
