76 R. W. CROSSKEY 



a separation into two tribes on the basis of the reproductive habit presents practical 

 difficulties of identification (since the external adult morphology of the genera 

 included in the redefined Goniini and Eryciini would not allow clear diagnosis, 

 nor would it lend itself to tribal key construction) . 



Key to Australian Tribes of Goniinae 



Pre-alar seta long and strong, longer than the first post ia seta and usually longer 

 than the first post dc seta (except in Bactromyiella). Sternopleuron often with 

 four stpl setae. Second costal sector bare ventrally. Subapical scutellar setae 

 never converging to enclose the apicals ........ 2 



Pre-alar seta small and weak, shorter than the first post ia seta (except in 

 Phorocerosoma) and normally much shorter than the first post dc seta. Second 

 costal sector bare or haired ventrally. Sternopleuron with fewer than four stpl 

 setae. Subapical scutellar setae sometimes convergent and enclosing the 

 apicals ............. 7 



Ocellar setae reclinate. Scutellum with a pair of stiff erect divergent preapical 

 setae. Frons very wide in both sexes, $ with outer vertical setae like the §. 

 Eyes bare. 3 + 4 dc setae ...... GONIINI (p. 96) 



Ocellar setae proclinate or absent (slightly divaricate in Paragonia). Scutellum 

 usually without stiff erect preapical setae just before the tip. Frons usually 

 not exceptionally wide, £ rarely with distinct outer vertical setae. Eyes bare 

 or haired. Various complements of dc setae ....... 3 



Eyes relatively very large so that the gena is reduced to a narrow strip below the 



eye that is not as wide as the profrons (Text-figs 48, 52 & 53) .... 4 



Eyes occupying relatively less of the side of the head, gena usually at least slightly 

 wider than the profrons (when doubtful check Winthemiini), often conspicuously 

 so (Text-figs 50 & 51) 5 



Propleural seta present. Legs blackish brown or mainly so, basicosta usually 



dark (yellowish in a few forms). [Parasites of Lepidoptera] . CARCELIINI (p. 89) 



Propleural seta absent (except in Koralliomyia) . Legs uniformly pale orange-yellow 

 or at most only femora brown, basicosta clear yellow-orange. [Parasites of 

 vespoid wasps] ANACAMPTOMYIINI (p. 90) 



Barette completely haired. Humeral callus with five strong setae (at least in the 

 <J) of which the three main ones stand in a triangle. Eyes densely haired. 

 Hind tibia of g with a long close-set ad fringe, g without definite reclinate 

 orbital setae. Scutellum with strong horizontal crossed apical setae and with the 

 subapical setae inserted far apart (distance between their bases at least as great 

 as that between a subapical seta and its corresponding basal seta) (Text-fig. 72) 



WINTHEMIINI (p. 88) 



Barette only haired at its anterior end (some exceptions : fully haired in Bactromyiella) 

 or entirely bare. Humeral callus with fewer than five setae, normally three setae 

 in a straight line and a fourth seta set forwards of the basal line of three 

 (sometimes only three setae in line or in a triangle). Eyes bare or haired. Hind 

 tibia with or without such fringe in the $. Arrangement of scutellar setae varied, 

 as above only in a few Sturmiini ......... 6 



Vibrissae inserted at a level distinctly above the epistomal margin (rarely only 

 slightly above). Always 3 + 4 dc setae. Inner posterior angle of the lower 

 calypter well developed, and inner margin of lower calypter abutted closely 

 against the scutellum. £ often with well developed close-set ad fringe on hind 

 tibia and sometimes with dense secondary sexual hair fascicles on venter of 

 abdominal T 4 STURMIINI (p. 91)
