Generic diagnosis.

Afrotropical species of Mesembrius s.s. (i.e. excluding representatives of the subgenus Mesembrius Vadonimyia , cf. Introduction) have the following combination of diagnostic characters: postpronotum pilose; compound eye bare (Figs 46 View Figures 46–51 - 82 View Figures 79–82 ); wing vein R4+5 strongly sinuate; wing vein M1 processive distally (Figs 127 View Figures 127–130 - 150 View Figures 147–150 ); wing cell r1 open (rarely, cell r1 is narrowly open as in Fig. 142 View Figures 139–142 ); thorax with katepimeron conspicuously pilose; and metabasitarsus with basoventral globuliferous setae (e.g. Figs 185 View Figures 185–188 , 196 View Figures 193–196 ).
