Abstract

The genus Hypotrix Guenee, 1852 is synonymized with Trichorthosia Grote, 1883, Proteinania Hampson, 1905, Ursogastra Smith, 1906, and Trichagrotis McDunnough, [1929]. Four species are transferred from the genus Hexorthodes McDunnough [Hypotrix trifascia (Smith, 1891), comb. n., H. alamosa (Barnes, 1904), comb. n., T. hueco (Barnes, 1904), comb. n., and T. optima (Dyar, 1920), comb. n.]. Four new species are described (T. basistriga Lafontaine, Ferris & Walsh; T. naglei Lafontaine, Ferris & Walsh; T. ocularis Lafontaine, Ferris & Walsh; and T. rubra Lafontaine, Ferris & Walsh). A new genus, Anhypotrix Lafontaine, Ferris & Walsh, is proposed for Polia tristis Barnes & McDunnough, 1910, currently misplaced in Trichorthosia. A key to species, descriptions, illustrations of adults and genitalia are included.
