- Abstract
Abstract. The Afrotropical Empidini are reviewed from a phylogenetic point of view. Seven monophyletic groups are recognized within the tribe, namely Empis (Coptophlebia ) bivittata , E. (C ) chrysocera , E. (C ) hyalea , E. (C ) namwamba , E. (C ) poecilosoma , E. (Disneyempis ) and E. setitarsus . Their monophyly is assessed by comparison with the remaining Empidini. The E. setitarsus -group is cladistically analysed to study the evolution of the length of vein M1 by optimization on the cladogram, and the status of subgenus Coptophlebia Bezzi is discussed. A key to the seven Afrotropical species-groups of Empidini is provided, genus Rhamphomyia is no longer recognized for the Afrotropical Region, and four new species belonging to the E. setitarsus -group, namely E. cinerarius sp.n., E. pseudosetitarsus sp.n., E. spinosa sp.n and E. spungaberaensis sp.n., are described and included in a key to all known species of this group.
