Updating the taxonomy, phylogeny and biogeography of the aberrant genus Coenosopsia Malloch (Diptera: Anthomyiidae)

Abstract Coenosopsia Malloch has eight known species distributed from southern North America to south-eastern South America. The of the genus are morphologically very homogeneous, and major differences remain in male terminalia. Remarkably, two main diagnostic characteristics Anthomyiidae absent this genus: setulae on ventral surface scutellum vein A 1 reaching wing margin. Some studies have attempted propose biogeographical narratives, primarily for Neotropical distribution genus. Herein, we describe three new north-eastern Brazil ( limeirai sp. nov.), ribeiroi central Mexico azteca nov.) present an identification key. In addition, updated phylogenetic analysis based morphological evidence, which recovered as monophyletic five synapomorphies four homoplasies. We also presented first hypothesis biogeographic methods (ancestral reconstruction character S-DIVA analyses), indicated a Mesoamerican origin
