Contribution to the systematics of Afrobaetodes Demoulin (Ephemeroptera : Baetidae)

Series of larval specimens of the genus Afrobaetodes Demoulin (Ephemeropter a: Baetidae) from Guinea, Ivory Coast, Kenya, Senegal, South Africa and Tan zania exhibit heretofore undocumented intraspecific variability. Specimens from Guinea, Ivory Coast and Senegal represent new distribution records. Af robaetodes pugio Gillies and A. intermedius Lugo-Ortiz & McCafferty are sho wn to be synonyms of A. berneri Demoulin, and A. delicatissimum (Barnard) i s shown lobe a synonym of A. pusillus (Navis). The larval stage of Afrobaet odes and the species A. berneri are redescribed. A taxonomic synopsis summa rizes the new revisions.
