Key to genera of Ephialtini
1 Abdominal tergite II with a pair of oblique furrows ( fig. 6a,b View Fig ) beginning nearly at its basomedial margin and running toward spiracles; first abdominal tergite comparatively long, usually as long as the second one; nervellus intercepted above its middle or rarely middle; the two radiomedial veins of the areolet nearly equal in length ( fig. 16a View Fig ); ovipositor cylindrical, usually not shorter than body ....................................................................................................................... 2
- Abdominal tergite II without distinct longitudinal-oblique furrows, first tergite shorter; areolet oblique; nervulus intercepted above its middle ( fig. 7c View Fig ); third radiomedial vein longer than second or absent ( fig. 8a View Fig ); ovipositor compressed or cylindrical, often quite short.......................................................................................3
2 Lower valve of ovipositor broadened apically and concealing the apex of upper valve, upper valve rounded dorsally and without a dorsal row of denticles ( fig. 9 View Fig )....... ..................................................................................................... Dolichomitus SMITH View in CoL
- Lower valves of ovipositor neither apically broadened nor concealing the apex of upper valve; upper valve with a dorsolateral row of denticles ( fig. 15c View Fig ) ..................... ........................................................................................................... Paraperithous HAUPT View in CoL
3 Occipital carina always distinct medially, straight or slightly curved upwards............ 4
- Occipital carina concave medially, weakly curved downwards, sometimes indistinct, rarely absent........................................................................................................................6
4 Nervellus intercepted below its middle or non-intercepted ( fig. 7c View Fig ); areolet absent ( fig. 7b View Fig ); hypopygium in females broad and protruding backwards; ovipositor gradually tapered towards apex and curved upwards ( fig. 7e View Fig ) .................... Clistopyga GRAVENHORST View in CoL
- Nervellus intercepted above its middle; sometimes areolet present ( fig. 22a,b View Fig ); hypopygium in females not protruding backwards; ovipositor straight with parallel sides ( fig. 22c View Fig )....................................................................................................................5
5 Areolet usually present ( fig. 22a,b View Fig ); propodeum more often without distinct subapicolateral swellings; basal tooth of ovipositor not enlarged, not higher than the others. ( fig. 22c View Fig ) ......................................................................... Tromotobia FOERSTER
- Areolet absent ( fig. 23a,b View Fig ); propodeum with distinct subapicolateral tubercles in females, in males these are weaker; basal denticle of ovipositor enlarged and higher, than the others ( fig. 23g View Fig ).......................................................... Zaglyptus FOERSTER View in CoL
6 Nervellus intercepted below its middle ( fig. 16c View Fig ); ovipositor often compressed, shorter than fore wing; metatarsomere II shorter than V or not more than 1.4 times as long as tarsomere V............................................................................................... 7
- Nervellus intercepted near or above its middle ( fig. 13b View Fig ); ovipositor compressed or cylindrical, often longer than fore wing, if shorter then metatarsomere II 1.5-2 times as long as V.............................................................................................................9
7 Abdominal tergite II. with distinct oblique furrows; the face in both sexes yellow; second recurrent vein emerging from outer corner of areolet as an extention of third radiomedial vein ( fig. 8a View Fig ); apex of upper valve of ovipositor slightly impressed after the node ( fig. 8b View Fig )......................................................................... Acropimpla TOWNES View in CoL
- Abdominal tergite II without oblique furrows; clypeus and face in both sexes black or of same colour as the head; second recurrent vein beginning between middle and outer corners of areolet ( fig. 16a View Fig ); apex of upper valve of ovipositor convex or flat or very rare barely concave laterally after the node ( fig. 16d View Fig )..............................8
8 Propodeum long, with clear and long, closely positioned mediolongitudinal carinae ( fig. 17d View Fig ); first abdominal tergite slender, 1.5-2 times as long as wide; scapus dark or, rarely, with a white spot beneath...................................................... Endromopoda HELLEN View in CoL
- Propodeum usually quite short, with more broadly separated mediolongitudinal carinae ( fig. 17e View Fig ); abdominal tergite I not so slender, usually not more than 1.5 times as long as wide; scapus often lightened beneath.................................................. Scambus HARTIG View in CoL
9 Clypeus strongly convex at least in basal half; ovipositor slightly compressed, the sheath 0.3-0.7 times as long as fore wing; metatibiae mostly with white and dark rings...................................................................................................................................10
- Basal half of clypeus flat; ovipositor different; metatibiae usually without distinct white and dark rings........................................................................................................11
10 Propodeum quite convex in lateral view; nervellus intercepted at or near its middle; clypeus in males black ........................................................................ Gregopimpla MOMOI View in CoL
- Propodeum not so convex in lateral view; nervellus intercepted near its upper third ( fig. 13b View Fig ); face and clypeus in males yellow ....................................... Iseropus FOERSTER View in CoL
11 Lower mandibular tooth longer than the upper one; clypeus 2.5 times broader than long; flat, yellowish-red, in males white; ovipositor sheath 1.8-5 times as long as fore wing; apex of ovipositor depressed, basal denticles at apices of lower valve strongly bent towards the base of ovipositor ( fig. 10b View Fig ) .............................. ...................................................................................................... Ephialtes GRAVENHORST View in CoL
- Lower mandibular, tooth not longer than the upper one; cIypeus 1.8 times broader than long, black or red; ovipositor sheath 1-2 times as long as fore wing; apex of ovipositor cylindrical or slightly compressed, basal denticles at apices of lower valve weakly bent towards the base of ovipositor ( fig. 11 e,f View Fig ).................12
