( Gonatocerus ) perforator (Ogloblin) ] or, if entire [ masneri species group of G. ( Cosmocomoidea )], the pronotum as long as mesoscutum and clearly visible in dorsal view, the head distinctly separated from mesoscutum; dorsellum rhomboidal or triangular ............................................................................................................................................... 3 2(1) Dorsellum with posterior margin straight ( Figs 71 , 78 ); propodeum with flat, usually spiculate median area bordered laterally by fine lines ....................................................................................................G. ( Lymaenon Walker ) stat. rev. - Dorsellum with posterior margin slightly sinuate, forming a little median projection ( Figs 160 , 169 , 173 ); propodeum with median groove ........................................................................ G. ( Gahanopsis Ogloblin ) syn. & stat. nov. 3(1) Back of head divided by transverse or oblique suture into gena ventrally and occiput dorsally; female gaster more or less (usually strongly) produced anteriorly under mesosoma .....................G. ( Gastrogonatocerus Ogloblin ) stat. rev. - Back of head entire or with a round or oval occipital sulcus; female gaster not or rarely slightly produced anteriorly under mesosoma............................................................................................................................................................ 4 4(3) Propodeum usually smooth medially or, occasionally, either with 1 usually faint median carina or 2 incomplete submedian carinae hardly visible as very fine lines, but forewing with setae extending to base of marginal vein ............ ............................................................................................................................... G. ( Gonatocerus Nees ab Esenbeck) - Propodeum usually with at least incomplete submedian carinae, but if rarely almost smooth medially then forewing with setae absent or sparse behind marginal vein ............................................
