Abstract: The Sepsidae is a family of flies of the Sciomyzoidea in the paraphyletic acalyptrate series of the Diptera. Sepsids are widely used as model organisms in behavioural studies and are characterized by dramatic sexual dimorphisms, such as the radically modified male forelegs. The forelegs have evolved within this family, and the divergent evolution of this trait corresponded to the evolution of a new copulation position that is derived within the Sepsidae. I document how the change from natural selection to sexual selection, resulted in the rapid evolution of morphological diversity. Moreover, I observe that the male foreleg armature was lost at least twice in Sepsidae.
