Key by Huber (2015):

Fore wing with microtrichia uniformly distributed to base of parastigma and usually fairly narrow, at least 3.8× as long as wide, with rounded apex; dorsellum triangular to rhomboidal and sometimes margined with lighter colour; propodeum smooth medially, rarely with two submedian carinae; funicle of female often with fl1 obliquely truncate dorsoapically, and fl2 and fl3 almost always longer than following funicle segments ... Gonatocerus Nees
– Fore wing almost always bare behind venation or, if setose, then microtrichia usually not uniformly distributed and less densely spaced than those beyond venation but if microtrichia uniformly distributed to base of parastigma (on one surface at least, e.g., Cosmocomoidea schajovskoii Ogloblin), then other features not all as above ... Cosmocomoidea Howard

I created a page for tribe Gonatocerini if you can't decide.

Thanks, John. On the female, I'm not seeing oblique truncation of fl1 (so it might be Gonatocerus), but fl2 and fl3 do seem longer than the following fl segments (so it might be Cosmocomoidea), although the difference with fl4 is slight. I've therefore moved the images to tribe level.
