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