Revision of the South American genus Gaujonia Dognin (Noctuidae, Pantheinae) with descriptions of five new genera and twenty-one new species

The endemic Neotropical genus Gaujonia Dognin is revised. Morphological characters and a phylogenetic analysis demonstrate paraphyletic relationships among the species. Four different groups are interpreted to represent four different genera. The G.arbosi group is the only remaining clade in the genus Gaujonia, and the other groups have been arranged into three new genera: Milleranagen. nov., Oculicattusgen. nov., and Cicadoformagen. nov. Additionally, two other genera Cicadomorphusgen. nov., and Gaujopteragen. nov. were found using morphological and molecular analyses based on some specimens that were misidentified as Gaujonia spp. A total of five new genera, three new combinations (Cicadoformavau-nigrum Hampson, comb. nov., Oculicattusrenifera Hampson, comb. nov., and Milleranaarbosioides Dognin, comb. nov.) and 21 new species (Cicadoformaocelotussp. nov., Cicadomorphuschicharrasp. nov., Cicadomorphuschuyasp. nov., Cicadomorphusfalkasiskasp. nov., Cicadomorphuslilianaesp. nov., Gaujoniabichusp. nov., Gaujoniachiqyaqsp. nov., Gaujoniakanakusikasp. nov., Gaujoniasourakovisp. nov., Gaujopteraamsasp. nov., Milleranaaustinisp. nov., Milleranacajassp. nov., Milleranacundinamarquensissp. nov., Milleranamatthewsaesp. nov., Milleranatigrinasp. nov., Oculicattusbolivianasp. nov., Oculicattusbrehmisp. nov., Oculicattusincasp. nov., Oculicattusraizaesp. nov., Oculicattusschmidtisp. nov., and Oculicattusuturunkusp. nov.) are established.
