On the taxonomy of the Afrotropical genus Crocosia Hampson with descriptions of a new genus and a new species (Lepidoptera: Erebidae: Arctiinae: Lithosiini)

The taxonomy of the footman moth genus Crocosia Hampson, 1914 is revised using morphological and molecular methods. Two species-group taxa are revived from synonymy to species level: Crocosia phaeocraspis Hampson, 1914 stat. rev. and Crocosia divisa (Gaede, 1924) stat. rev. A new genus and a new species are described: Cragiosia gen. n. (type species: Ilema mesosticta Hampson, 1911) and Cragiosia smithi sp. n. (Liberia and Guinea). A new combination is introduced: Cragiosia mesosticta (Hampson, 1911), comb. n. Adults as well as male and female genitalia of all species of Crocosia and Cragiosia gen. n. along with the type species of the allied genus Cragia Birket-Smith, 1965 are illustrated.
