RECLASSIFICATION OF MICROGASTERINI 17 



Second transverse cubitus always received onto the 2nd abscissa of the radius at 

 its extreme base or interstitial with the 1st abscissa of the radius (Text-fig. 339) ; 

 propodeum rugose, usually strongly so and with more or less distinct medial keel 

 but never with areola ; vannal lobe beyond its widest part feebly convex and 

 fringed with hairs throughout. Old and New World 



M1CROGASTER Latreille (p. 267) 



- If tergite 1 is at all widened towards apex, then tergite 2 is much shorter than 3 and is 



virtually smooth and polished all over and the 2nd transverse cubitus is received on 



to the 1st transverse cubitus so that the areolet is very small .... 19 



19 Median field of tergite (2 +3) always strongly transverse, neither triangular nor 



subtriangular and appearing very short in comparison with the rest of the tergite 

 beyond it. 



Ovipositor always projecting freely beyond the apex of the gaster, its sheaths 

 at least half as long as the hind tibia ........ 20 



- Median field of tergite (2 + 3) never transverse, having a pronounced triangular or 



subtriangular form or elongate-oval . . . . . ... 21 



20 Inner spur of the middle tibia much shorter than the middle basitarsus ; areolet 



extremely small . . PROMICROGASTER Brues & Richardson (p. 229) 



- If the inner spur of the middle tibia is obviously shorter than the middle basitarsus, 



then the areolet is much larger or the propodeum has a median longitudinal keel 



HYPOMICROGASTER Ashmead (p. 208) 



21 Mouth parts lengthened, the glossa deeply forked and the galea much longer than 



wide ; propodeum polished and without keel or areola ; hypopygium very long, 

 membranous, tightly folded along the middle line in death ; ovipositor very long, 

 its sheaths fully one and a half times longer than the hind tibia ; median field of 

 tergite (2 + 3) much longer than wide . . . SENDAPHNE gen. n. (p. 203) 



- Mouth parts not at all lengthened, the glossa and the galea normal ; propodeum 



rugose, with or without a medial keel (polished and without a keel in the tegularis- 

 group) ; hypopygium short (but only male of tegularis-growp known), more or less 

 evenly sclerotised throughout and not tightly folded along the middle line in death ; 

 ovipositor very short, almost hidden ; median field of tergite (2 + 3) a t most 

 slightly longer than wide . . PROTOMICROPLITIS Ashmead (p. 234)

Key to Species-groups 

 Females 



1 Plate of tergite 1 four to five times as long as its apical width, more or less constricted 



medially and deeply grooved almost to apex ....... 2 



- Plate of tergite 1 not of this shape or, if it is long and tends to be constricted 



medially, then it is without a percurrcnt groove (pislrinariae-group and, except- 

 ionally, in ater-group) .......... 3 



2 Brachial vein, where it is closest to the wing-edge, separated from the wing-edge by 



less than its own width (Text-fig. 114) ; disc of scutellum separated from the 

 posterior, polished band by a lip or ridge ; hind coxa above and towards apex with 

 one or two longitudinal ridges and towards apex with many strongly raised 

 wrinkles that form an irregular reticulation . . . henicopus-group (p. 197) 



- Brachial vein at its closest to the wing-edge separated from the wing-edge by fully 



its own width ; disc of scutellum flattened, polished and not separated from the 

 the posterior, polished band of the scutellum ; hind coxa above without longi- 

 tudinal ridges though transversely ribbed towards apex. 



Very large, fulvous species, ca. 5-5 mm. with deeply notched claws and wide, 

 transverse face. New Britain ...... daira-group (p. 198)
