Abstract

Coenosiini (Diptera: Muscidae) is a large cosmopolitan tribe of muscids, within which Coenosia Meigen and Neodexiopsis Malloch are the genera with the largest number of species. In this work, we revised for the first time, all the species placed by Malloch (1934) under Austrocoenosia, an endemic genus from the Andean Patagonian Forests, whose species are now placed in Coenosia and Neodexiopsis. We provide detail redescriptions for eight species placed by Malloch (1934) under Austrocoenosia, and decribed two new species (Coenosia delneneosp. nov. and Coenosia patagonicasp. nov.), with high quality photographs detailing new structures of the male and female terminalia. To establish the position of the species of Austrocoenosia with respect to Coenosia and Neodexiopsis, we made a phylogenetic analysis using implied weighting for 36 taxa and 132 morphological characters of adults, including male and female genitalia. We recovered all species of Austrocoenosia as Coenosia species. We propose the following nomenclature actions: Austrocoenosia as a junior synonymy of Coenosia (syn. rest.); Coenosia brevicornis (Malloch) (comb. nov.), Coenosia dubia (Bigot) (comb. rest.); Coenosia hucketti, Pont (nom. nov.) and Coenosia nigerrima (Malloch) (comb. rest.). We also propose Coenosia spumicola Pont as an unplaced species of Coenosia sensu lato. Finally, we updated the geographic distributions for all species and observed several new male and female terminalia structures, which enriched the discussion of the genera and the tribe.
