New Australian stiletto flies: revision of Manestella Metz and description of Medomega gen. n. (Diptera, Therevidae, Agapophytinae)

Abstract. The previously monotypic genus Manestella Metz, 2003 is revised with a single species, Manestella tristriata (Mann, 1933), redescribed and an additional 14 new species described: Manestella caesia sp. n., Manestella campestris sp. n., Manestella canities sp. n., Manestella cooloola sp. n., Manestella fumosa sp. n., Manestella incompleta sp. n., Manestella nubis sp. n., Manestella obscura sp. n., Manestella ocellaris sp. n., Manestella persona sp. n., Manestella poecilothorax sp. n., Manestella umbrapennis sp. n., Manestella vasta sp. n. and Manestella vespera sp. n. The putative sister genus to Manestella, Medomega gen. n., is described containing six new species: Medomega averyi sp. n., Medomega bailmeup sp. n., Medomega chlamydos sp. n., Medomega danielsi sp. n., Medomega gigasathe sp. n., and Medomega nebrias sp. n. Complete taxonomic descriptions were generated from a character matrix developed in Lucid Builder from which natural language descriptions (NLD) were parsed. Images of all species of Manestella and Medomega gen. n. are included, along with dichotomous keys to species.
