Antlered richardiid flies: New species of Richardia (Tephritoidea: Richardiidae) with antler-like genal processes

Abstract

Within Richardiidae, Richardia infestans, from Colombia, is the only known species to have genal processes, which are structures formed by the extension of the cuticle on the lateral margin of the gena. In the present work, six new species, with different patterns of antler-like genal processes, are described. An identification key and illustrations are provided. Richardia bella sp. nov., R.modesta sp. nov. and R.vitta sp. nov. are recorded from Costa Rica; R.advena sp. nov. is recorded from Costa Rica and Panama; R.simplex sp. nov. is recorded from Panama; and R.ornatella sp. nov. is recorded from Ecuador. © 2015 The Entomological Society of Japan.
