https://en.wikipedia.org/wiki/Hybotidae They belong to the superfamily Empidoidea and were formerly included in the Empididae as a subfamily. The Hybotidae clearly form a lineage quite distinct from the Empididae. Among the Empidoidea, they represent a lineage more basal than the main radiation of Empididae and Dolichopodidae. By and large, the Hybotidae are monophyletic.
