Revision of the comose flame moths of the genus Sosxetra Walker (Noctuidae, Dyopsinae), with descriptions of a new genus and three new species

As part of our Neotropical Dyopsinae Project, a revision of the Neotropical genus Sosxetra Walker is proposed. Morphological and molecular evidence challenge its previous monotypic classification. The genus is redescribed and a neotype is designated for Sosxetra grata Walker, previously considered the only species in the genus. Two new species are described: Sosxetra mamanina Martinez, Homziak, & Castillo-Argaez, sp. nov. and Sosxetra thutakanay Martinez, Homziak, & Castillo-Argaez, sp. nov. Finally, Covellana Martinez, Homziak, Plotkin & Castillo-Argaez, gen. nov., is established based on Covellana niomalan Martinez, Homziak, Plotkin & Castillo-Argaez, sp. nov., previously misidentified as Sosxetra grata.
