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). 
KeEy To AUSTRALIAN TRIBES OF GONIINAE 
1 Pre-alar seta long and strong, longer than the first post 7a seta and usually longer 
than the first post dc seta (except in Bactromyiella). Sternopleuron often with 
four stpl setae. Second costal sector bare ventrally. eat scutellar setae 
never converging to enclose the apicals . - : 2 
— Pre-alar seta small and weak, shorter than ie ae as 1a fa (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 stp/ 
setae. Subapical scutellar setae sometimes convergent and enclosing the 
apicals : : : : - - : : : : : : 7 
2 Ocellar setae ses Ses, Scutellum with a pair of stiff erect divergent preapical 
setae. rons very wide in both sexes, g with outer vertical setae like the 9. 
Eyes bare. 3 + 4 dc setae ; : ; : ; : GONIINI (p. 96) 
— Ocellar setae proclinate or absent (slightly divaricate in Pavagonia). Scutellum 
usually without stiff erect preapical setae just before the tip. Frons usually 
not exceptionally wide, g rarely with distinct outer vertical setae. Eyes bare 
or haired. Various complements of dc setae . : 3 
3. Eyes relatively very large so that the gena is reduced to a narrow an 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) . : : é ; : : : 4 : : 5 
4 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 Kovalliomyia). Legs uniformly pale orange-yellow 
or at most only femora brown, basicosta clear yellow-orange. [Parasites of 
vespoid wasps] . ‘ . ANACAMPTOMYIINI (p. 90) 
5 Barette completely fe Hagnecal callus with five strong setae (at least in the 
6) 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 ina 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 
6 Vibrissae inserted at a level distinctly above the ppeeaeel eee inate ouilg 
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. 4 often with well developed close-set ad fringe on hind 
tibia and sometimes with dense secondary sexual hair fascicles on venter of 
abdominal T4  . : : : : : : ; . STURMIINI (p. 91)
