Labiobaetis Novikova & Kluge in West Africa (Ephemeroptera, Baetidae), with description of a new species

Abstract
Material collected between 1984 and 1988 in Guinea and Mali and between 2003 and 2008 in the Ivory Coast substantially increased our knowledge of Labiobaetis Novikova & Kluge in West Africa. We identified eight different species using morphological characters. One species, L. ediai sp. nov., is new to science; it is described and illustrated, based on its nymphs. The status of L. boussoulius (Gillies, 1993) is discussed and the divergent morphology of L. elouardi (Gillies, 1993) is compared to other species of Labiobaetis. A key to the nymphs of all West African species is provided and the distribution of Labiobaetis species in the Afrotropical realm is discussed.
