Study of recent collections and types shows that the genus Archocopturus Heller is both more and less diverse than previously thought. Specimens included under the name Archocopturus regalis (Boheman) are a complex of species that are superficially very similar, probably because they participate in a single mimicry complex whose models are flies of the genus Medetara (Dolichopodidae). Archocopturus regalis is apparently limited to northern South America. Four species are described from Central America and others are known from South America. Archocopturus pulchellus Hustache is transferred to the previously monotypic genus Zygopsella and A. basalis Hustache to a new genus.

Species 1: Coleoptera Curculionidae Archocopturus regalis
Species 2: Diptera Dolichopodidae Medetera spp
Species 3: Coleoptera Curculionidae Zygopsella ruficauda
Keywords: mimicry, sibling species
