Drapetis sp., copyright Proctoss.
Belongs within: Empidoidea.

The Hybotidae are a group of long-legged flies previously classified in the Empididae, albeit as a distinct group ‘Ocydromiinea’. Males of this family have the terminalia rotated 90° to the right. Within the family, the Tachydromiinae are characterised by wings that lack both cell dm and obvious forks in veins R4+5 and M1+2 (Steyskal & Knutson 1981).

Characters (from Steyskal & Knutson 1981, as Ocydromiinea): R5 not separated from R4; Sc ending free in membrane or running indistinctly alongside apical part of R1, not attaining C; C ending at end of M, or R5; precoxal bridge reduced; lacinia of maxilla lacking or reduced; palpus removed from stipes and joined to a special sclerite (palpifer); mouthparts movable into anteriorly directed position; fore tibia with gland near base opening posteroventrally; abdominal spiracles with tubiform opening, without microtrichia; terminalia of male twisted to right; female without sclerotised spermathecae.
