RECLASSIFICATION OF MICROGASTERINI 13 



Hind wing without a closed cubitellan cell and without a differentiated vannal lobe ; 

 external, distal corner of the submediellan cell always close to the edge of the wing ; 

 2nd cubital cell, if present, never in the form of a small areolet. 



2nd transverse cubital vein always absent ....... 3 



1 Both transverse cubital veins wanting ; basal vein strongly curved just before its 

 junction with the prostigma. 



Tergite 1 with a heavily sclerotised, median plate, its spiracle set in a small prom- 

 inence on the lateral edge of this plate ; hind spurs extremely short, the inner one 

 from one fifth to one quarter as long as the hind basitarsus ; a short metacarp either 

 absent or present ; propodeum smooth ; pedicel equal to fully half the length of 

 the scape (much as in Mirax) ; no percurrent flange beneath the hind basitarsus, 

 such as occurs in the Microgasterini . . PAROLIGONEURUS Muesebeck 



• 1st transverse cubital vein present ; basal vein without this conspicuous bend . . 4 



1st transverse cubital vein joined with the radius and cutting off a well defined 1st 

 radial abscissa (the usual condition of the generalised braconid wing). 



Scape rather long, fully twice as long as the pedicel ; propleurum laterally with a 

 flange that overlaps the lateral edge of the pronotum ; propodeum completely 

 areolated and with seven discrete fields ; prepectus margined, at least laterally ; 

 inner spur of the hind tibia reaching beyond middle of hind basitarsus ; hind 

 basitarsus with percurrent flange beneath ; tergite 1 with oblong, median, heavily 

 sclerotised plate, on extreme edge of which is situated the spiracle (cf. Mirax). 



DIRRHOPE Forster 

 1st transverse cubital vein joined or almost joined with the stigma ; hence, not cutting 



off a clearly defined 1st radial abscissa ........ 5 



1 Antenna 14-sgemented ; pedicel long in proportion to length of scape, fully two 

 thirds as long ; occiput not margined ; tergite 1 with strongly sclerotised, discrete 

 median plate (as in the Microgasterini) ; spiracle of 1st tergite situated on the 

 latero-tergite, remote from the median plate ; hind spurs very short, the inner one 

 not reaching to middle of the hind basitarsus ; fore wing without metacarp, at most 

 the stigma somewhat prolonged distally (Text-fig. 4) ; hind tibia not swollen and 

 not characteristically club-shaped ...... MIRAX Haliday 



- Antenna 20-segmented ; pedicel short in proportion to length of scape ; scape un- 



usually long ; occiput margined ; tergite 1 without a discrete median plate ; the 

 posterior margin of this tergite either not defined or defined by a curved furrow that 

 reveals the tergite as being strongly transverse ; spiracle of tergite 1 situated on 

 extreme edge of dorsal surface ; hind spurs longer, the inner one reaching beyond 

 middle of the hind basitarsus ; metacarp short but distinct (reduced to a mere 

 stub in an undescribed species of Paradelius from S. Africa) ; hind tibia strongly 

 swollen towards apex (as in many Cheloninae). 



Flagellum of female thickened medially ....... 6 



> Gaster entirely smooth ; no furrow between tergites 1 and (2 + 3). Wings (Text- 

 fig. 2) ADEL1US Haliday 



- Gaster rugose on at least basal half ; a rugose furrow between tergites 1 and (2 + 3).
