Abstract


Ten new Afrotropical species of Pterophoridae are described: Agdistis linnaei spec. nov., Agdistis bouyeri spec. nov., Ochyrotica bjoernstadti spec. nov., Platyptilia aarviki spec. nov., Stenoptilia kiitulo spec. nov., Exelastis caroli spec. nov., Eucapperia continentalis spec. nov., Buckleria vanderwolfi spec. nov., Pselnophorus meruensis spec. nov., and Hellinsia emmelinoida spec. nov. The species are illustrated in colour, and their genitalia in line drawings.

Introduction


In the late 19th and early 20th century three British authors (Lord Walsingham, Edward Meyrick and T. Bainbridge Fletcher) studied Pterophoridae species from the African continent. After that period very little has been published until the late 20th century, when authors like Arenberger, Bigot, Gibeaux and Gielis started their studies on this fauna. Most publications from this period are small contributions, except for the review of the collections in the Royal Museum for Central Africa (Bigot, 1969), and a faunistic review of Madagascar (Gibeaux, 1994). This relatively low number of publications is mainly due to the limited collecting of Pterophoridae in Africa.

In recent years some western European entomologists successfully collected Pterophoridae in the Republic of South Africa, Kenya and Tanzania. Although a revision of the Pterophoridae from the African continent would have been preferable, the small amount of material and the many difficulties to collect in various regions are preventing a comprehensive review at this stage. I have chosen to merely describe the new species from these recent collections here. The sequence of the species follows the World Catalogue of Insects: Pterophoroidea and Alucitoidea (Gielis, 2003).

The type specimens that are currently placed in the collection of the author, will later be deposited in the National Museum of Natural History in Leiden, The Netherlands; the private collection of Leif Aarvik will be placed in the National Natural History Museum, Oslo, Norway.

The present publication is the sixth in a series of papers on Afrotropical Pterophoridae (Gielis, 1986; 1990; 1991a; 1991b; 2002).
