TACHINIDAE OF AUSTRALIA 
Vibrissae usually inserted about on a level with the epistomal margin (if above then 
other character not fully fitting or doubtfully so). Dorsocentral setae sometimes 
3 + 4 but other complements occurring. Inner margin of lower calypter usually 
not closely following edge of scutellum, inner posterior angle of the calypter 
usually rather rounded. ¢ without a oa, close-set hind tibial fringe and 
without abdominal hair fascicles. : : ERYCIINI (p. 96) 
Scutellum with three pairs of very strong setae in which the apical setae are crossed 
and horizontal and the subapical setae are very wide apart and inserted well 
forwards on the sides of the scutellum (Text-fig. 68); no lateral scutellar setae. 
Basal node of R,,; with one strong setula. Parafrontals in both sexes with a 
long series of strong proclinate orbital setae. Antenna with the anterior tip of 
the third segment forming a sharp point. Bend of vein M widely obtuse, M, 
unusually straight and cell Rk; normally closed at the wing marginor short-petiolate 
(Text-fig. 88). Second costal sector haired ventrally. 2+ 3 dc setae. 
[Parasites of Orthoptera Acridoidea] . : : ACEMYINI (p. 78) 
Scutellum almost always with different conformation of setae, lateral setae usually 
present; if scutellar bristling similar then other characters not fitting. Basal 
node of R,,; with more than one isolated setula (except in Neaerini and a few 
Blondeliini). Parafrontals with the usual two pairs of proclinate orbital setae 
in 9, without or with two pairs in g. Antenna not noticeably mucronate, outer 
tip of last segment usually rounded. Wing venation of different form (slightly 
similar in some Blondeliini). Second costal sector haired or bare below. Varied 
complements of dc setae. [Not parasites of ee Acridoidea, a 
possibly Phorocerosoma| 
Subapical scutellar setae stronely convergent or Grossing a them: pe 
(Text-figs 67 & 69). Second costal sector haired below (third sector also usually 
haired ventrally on most of its length). Costal margin conspicuously broken 
and incised at the apex of the subcosta (Sc) (Text-figs 86 & ty). Abdominal 
Tr + 2 not excavate to its hind margin 
Subapical scutellar setae parallel to each other or diverging fe: g. as in Text- ies a1). 
Second costal sector bare below (except in Livophaga). Costal margin 
inconspicuously broken and scarcely at all incised at the apex of Sc. Abdominal 
Tr + 2 usually excavate to its hind margin (not in some Blondeliini or in 
Hillomyia) , : é ; . : : . 
Abdomen without discal setae on nany eeeite. Propleuron bare. Head not sexually 
dimorphic, g with two pairs of proclinate orbital setae and with outer vertical 
setae like the 9. Vein R,,, extensively setulose and F, usually also partly or 
wholly setulose. Eyes bare. Hind tibia with three dorsal preapical setae 
(pd preapical present in addition to the usual ad and d preapicals) (Text-fig 18) 
Io 
SIPHONINI (p. 80) 
Abdomen with strong erect discal setae on tergites 3 to 5. Propleuron haired. 
Head sexually dimorphic, frons much narrower in ¢ than Q and male head 
without proclinate orbital setae or definite outer vertical setae. Vein Ry, ; with 
one setula only or a small tuft of setulae confined to the basal node, R, bare. 
Eyes haired (but hairing very short and inconspicuous in some forms). Hind 
tibia with two dorsal preapical setae (the normal ad and d preapicals) (Text-fig. 19) 
NEAERINI (p. 78) 
Bend of vein M in the form of an open evenly rounded curve (as in Text-fig. 85) or 
if shightly abrupt then forming a widely obtuse angle, always without trace of an 
M, appendix or fold. Propleuron bare or haired. Infrasquamal hairs present 
or absent. Abdominal Tr + 2 excavate or non-excavate to its hind margin. 
Mid tibia with or without a submedian v seta , 
Bend of vein M abrupt and not forming a widely obtuse angle (JV changing direction 
usually at about 90° at the actual bend), often provided with an M, appendix or 
BLONDELIINI (p. 81)
