Key to genera allied to Pleurotroppopsis Girault

1 Pronotum and mesoscutum with distinct shoulders (e.g. Fig. 8b ); propodeal spiracle elongate (e.g. Fig. 2c ); callus of propodeum with numerous setae scattered over almost entire surface (e.g. Fig. 2c ) or at least more than 4 setae (e.g. fig. 1C in Gumovsky 2007); femora metallic or dark brown..................................................................... 2

- Pronotum and mesoscutum without distinct shoulders; propodeal spiracle round; callus of propodeum usually with 2 or 3 setae (sometimes more, but never setose over entire surface); femora pale yellow or whitish.............................. 4

2(1) Propodeum with a median groove delimited by 2 subparallel fine carinae, without plicae (e.g. fig. 1C in Gumovsky 2007); propodeum with grooves along anterior margin beside submedian carinae (e.g. fig. 1B in Gumovsky 2007); transoccipital ridge absent (e.g. fig. 1A in Gumovsky 2007); tibiae whitish.................................... Afrotroppopsis Gumovsky

- Propodeum without a median groove, but with a median carina and plicae (e.g. Fig. 8b ); submedian areas without grooves along anterior margin (e.g. Fig. 8b ); transoccipital ridge present (e.g. Fig. 4b ); tibiae usually metallic or brown, occasionally with metatibia whitish..................................................................................... 3

3(2) Frontal carina present (e.g. Fig. 8a ); Gt 1 anterolaterally with an eye-like patch at each side (females only) (e.g. Figs 8c , 12d ); propodeum with spiracular areas not depressed anteriorly and with a spiracular area narrower than a submedian area (e.g. Fig. 8b ); posterior transverse margin of propodeal submedian areas well delimited from plicae (e.g. Figs 8b , 9b ).............................................................................................. Pleurotroppopsis Girault

- Frontal carina absent; Gt 1 without eye-like patch; propodeum with spiracular areas with anterior depression and with a spiracular area larger than a submedian area; posterior transverse carina of propodeal submedian areas not well delimited from plicae................................................................................... Parahorismenus Girault

4(1) Scutellum with a distinct longitudinal median groove along most of its length..................................... 5

- Scutellum without longitudinal median groove.............................................................. 6

5(4) Propodeum with a broad and smooth median area delimited by strong plicae and posterior transverse carina, and without a median carina or submedian carinae although sometimes with small irregular carinae anteriorly and posteriorly (e.g. fig. 6D in Gumovsky 2007)................................................................. Zaommomentedon Girault

- Propodeum with a broad and carinate median area delimited by strong plicae and posterior transverse carina, and with 2 broadly divergent submedian carinae without small carinae between them (e.g. fig. 6C in Gumovsky 2007).... Schizocharis Kerrich

6(4) Lateral panel of pronotum with a straight longitudinal carina; female upper face not raised above frontal suture; MLM usually with a median groove posteriorly; PMV long, more than 2× as long as STV; propodeum with 2 broadly divergent submedian carinae or a raised media carina, with plicae................................................................ 7

- Lateral panel of pronotum usually with a weakly curved longitudinal carina (e.g. fig. 5B in Gumovsky 2007); upper face of female usually raised above frontal suture (e.g. fig. 3 in Hansson 2012); MLM without a median groove; PMV short, less than 1.5× as long as STV; propodeum variable, medially with (e.g. fig. 42 in Hansson 2012) or without (e.g. fig. 31 in Hansson 2012) a median carina or 2 narrowly divergent (e.g. fig. 15 in Hansson 2012) or somewhat parallel submedian carinae (e.g. fig. 47 in Hansson 2012), and with or without plicae.............................................. Achrysocharoides Girault

7(6) Propodeum with complete and more or less parallel plicae and a complete median carina, but without paraspiracular carinae (e.g. fig. 4D in Gumovsky 2007); upper face with a pit or a short groove below anterior ocellus; petiole elongate, pyriform..................................................................................... Apleurotropis Girault

- Propodeum with plicae and 2 broadly divergent submedian carinae, anteriorly with small carinae between them, and with distinct paraspiracular carinae; upper face without a pit or a short groove below anterior ocellus; petiole reduced, transverse (e.g. fig. 6A in Gumovsky 2007).......................................................... Platocharis Kerrich
