Second contribution to the knowledge of the Lithosiini of Gabon: the genus Nanna Birket-Smith (Lepidoptera, Erebidae, Arctiinae)

摘要

The presence of the genus Nanna in Gabon is treated. Four species are recorded, two of which are new to science ( N. molouba sp. nov. and N. semigrisea sp. nov.), and the hitherto unknown female of Nanna ceratopygia is described. A checklist and a key to the species of the genus Nanna are provided.
