New faunistic data from Namibia are given for the family Metarbelidae. A total of 17 species are recorded and a new species is described: Metarbela dietermeyi sp. nov. The adults of the new species and specimens of Lukeniana raymondrevellii and two Selagena species are illustrated in colour. The male genitalia and wing venation of M. dietermeyi sp. nov. are depicted as line drawings and its systematic position is briefly discussed.

The author reports on the occurrence of Ithome concolorella on Ascension Island. Although it is a relatively recent introduction, the species has spread quickly over all parts of the island, with highest abundances recorded in lower and mid altitudes. Larvae have not yet been found, but it is assumed that they feed on introduced plant species, such as Mexican Thorn, Prosopis juliflora and Horse Tamarind, Leucaena leucocephala.
