4. Antenna (a1) with only 2 funicular segments and submarginal vein (b1: s) smoothly meeting premarginal vein (except in some Aulogymnus), with more than 2 dorsal setae, and scutellum (c1) with 2 pairs of setae.
note: Some Aulogymnus and some very small specimens of Cirrospilus do not place well in this couplet because the junction between the submarginal and premarginal veins is broken. They always have 3 or more submarginal vein setae, and 2 pairs of scutellar setae, and parallel or subparallel dorsal scutellar grooves that do not curve to meet posteriorly (as in d1), and 2 funicular segments (for all Cirrospilus and all applicable species of Aulogymnus).

4'. If antenna with 2 funicular segments, then submarginal vein (bb1: s) not smoothly meeting premarginal vein (ie: parastigma projecting far posteriad of submarginal vein and their junction broken) and scutellum (cc1) almost always with 1 pair of setae.
