Salden, Tobias & Peters, Ralph S., 2023, Afrotropical Ceraphronoidea (Insecta: Hymenoptera) put back on the map with the description of 88 new species, European Journal of Taxonomy 884 (1), pp. 1-386 : 11

Key to genera of male Ceraphronidae from the Afrotropical mainland (modified from Dessart & Cancemi 1987)

1. Mesosoma laterally compressed (higher than wide); flagellomeres cylindric or trapezoidal with erect and/or sickle-shaped sensillae (longer and/or shorter than width of flagellomeres) ......................... 2

– Mesosoma not laterally compressed (often wider than high); flagellomeres cylindric with sickle-shaped sensillae (rarely longer than width of flagellomeres) ( Dessart & Cancemi 1987: e.g., 363, figs 104–111) ................................................................................................. Ceraphron Jurine, 1807

2. Head not dorsoventrally flattened ..................................................................................................... 3

– Head dorsoventrally flattened and distinctly wider than laterally compressed meso- and metasoma ( Dessart & Cancemi 1987: 347, figs 31–32) .................................................. Synarsis Förster, 1878

3. Head without modified vertex and elongated mandibles .................................................................. 4

– Head with elongated, slightly flattened and medially notched vertex; elongated and thin mandibles ( Dessart & Cancemi 1987: 348, figs 35–39) ....................... Gnathoceraphron Dessart & Bin, 1980

4. Head not enlarged and not subdivided by distinct carinae into concave compartments .................. 5

– Head enlarged with subdivided concave preoccipital and frontal compartments, subdivision by distinct carinae; elongated mandibles ( Dessart & Cancemi 1987: 348, figs 40–42) .... Retasus Dessart, 1984

5. Anterior third of metasoma narrowed, rest of metasoma distinctly convex ventrally; flagellomeres cylindric with sickle-shaped sensillae shorter than width of flagellomeres ( Dessart & Cancemi 1987: 350, fig. 49; Fig. 92D ) .......................................................................... Cyoceraphron Dessart, 1975

– Metasoma without characteristic profile; flagellomeres trapezoidal (rarely cylindric) with erect and/ or sickle-shaped sensillae mostly longer than width of flagellomeres ( Dessart & Cancemi 1987: 351, figs 52–53; Figs 28D , 30D ) ................................................................ Aphanogmus Thomson, 1858
