Key to Madagascan genera of Microdontinae  

A key to the genera of Microdontinae   of the world can be found in Reemer & Ståhls (2013). In the Afrotropical region, the key below may be used to recognize the African genera.

1 Abdomen oval (may be short or elongate) ( Figs 7 View FIGURES 7 – 10 , 12 View FIGURES 11 – 15 , 30 View FIGURES 30 – 31 )..................................................... 2

- Abdomen petiolate ( Fig. 1 View FIGURE 1 ).............................................................................. 4

2 Vein R 4 + 5 with posterior appendix extending into cell r 4 + 5 ( Figs 8 View FIGURES 7 – 10 , 18, 19 View FIGURES 18 – 23 )....................................... 3

- Vein R 4 + 5 without posterior appendix ( Fig. 2)............................................ Afromicrodon Thompson  

3 Antennae shorter than distance between antennal fossa and anterior oral margin (as in Fig. 4). Male genitalia: hypandrium with basolateral bulges, phallus wide, apically furcate ( Fig. 3)....................................... Archimicrodon Hull  

- Antennae longer than or as long as distance between antennal fossa and anterior oral maring ( Figs 8 View FIGURES 7 – 10 , 21 View FIGURES 18 – 23 ). Male genitalia: hypandrium without basolateral bulges, phallus more slender, apically or basally furcate (e.g. Figs 10 View FIGURES 7 – 10 , 15 View FIGURES 11 – 15 , 29 View FIGURES 26 – 29 , 53 View FIGURES 49 – 53 )..................................................................................... Microdon Meigen   (see next key)

4 Occiput without crease ( Figs 21 View FIGURES 18 – 23 , 57 View FIGURES 56 – 61 , 52 View FIGURES 49 – 53 ). Metapleura connected, forming postmetacoxal bridge........................ 5

- Occiput with deep dorsolateral crease (Fig. 4). Metapleura separate, not forming postmetacoxal bridge.................................................................................................. Spheginobaccha   de Meijere

5 Mesonotum with transverse suture complete, uninterrupted medially. Tergites 3 and 4 separate, not fused. Male with long pilosity on basoflagellomere ( Fig. 20 View FIGURES 18 – 23 in Reemer & Ståhls 2013 b)............................... Ceratrichomyia Séguy  

- Mesonotum with transverse suture incomplete, interrupted medially. Tergites 3 and 4 fused. Male without long pilosity on basoflagellomere................................................................... Paramixogaster Brunetti
