TACHINIDAE OF AUSTRALIA 85 
— Vibrissae inserted well above the level of the epistomal margin. Eyes bare or 
haired. Parafacials completely haired or haired at least on the upper halves. 
Ocellar setae usually absent or weak, sometimes moderately strong in9. Apical 
scutellar setae usually very weak and hair-like, sometimes absent, seldom well 
developed . P : 5 
15 Facial regions of head with yellow or orange ground colour and bright yellow 
pollinosity. Eyes bare. Basicosta reddish yellow. Legs usually all or mainly 
reddish yellow, at least tarsi reddish yellow. Haired areas of parafacials not 
nearly contiguous with haired areas of genal dilations (therefore a conspicuous 
bare area between haired part of parafacial and the gena). On average larger 
forms, length 7-12 mm, often with yellow to golden orange hair on sides of thorax 
and sometimes also the abdomen . ; : . FROGGATTIMYIA Townsend 
— Facial regions of head with rather indeterminate ground colour, not bright yellow 
and if pale usually rather reddish, pollinosity greyish white to very pale yellowish. 
Eyes bare or haired, often densely haired. Basicosta nearly always dark brownish 
or blackish brown. Legs brownish black, sometimes with reddish or reddish 
yellow tibiae, tarsi dark (except for reddish yellow fore tarsi in male of A. 
scutellata). Haired areas of parafacials nearly contiguous with haired areas of 
genal dilations (only a very narrow bare gap between parafacial and genal 
hairing). On average smaller forms, length 5-9 mm, without pale hair on thorax 
or abdomen . : . : ; . MANAGONIA Brauer & Bergenstamm

and Anagonia| 
Tribe EXORISTINI 
The exoristines are moderately well represented in Australia and Tasmania, 
seven genera being known from the area. None is endemic, and several of them 
occur widely in the Oriental Region (Eozenillia, Austrophorocera) or in most of 
the zoogeographical regions (Exorista, Stomatomyia); Hillomyia (= Hillia Malloch, 
preocc.) is known from only a few specimens but is perhaps an essentially Papuan 
genus that has reached the Northern Territory of Australia. 
The tribe is reasonably distinctive, possessing the combination of small pre-alar 
seta plus non-convergent subapical scutellar setae plus abruptly angulate bend to 
vein M (the bend normally accompanied by at least a trace of a fold in the position 
of M, continuing towards the wing margin, Text-fig. 87); the genera found in 
Australia have unusually dependable characters, and most are considerably easier 
: to identify reliably than the genera in most other goniine tribes. Some features 
common to all the Australian exoristines may be usefully noted as follows: 
prosternum always haired; male always without proclinate orbital setae; mid 
tibia with a submedian v seta; mid tibia with two or more ad setae; hind tibia 
always without #d preapical seta; second costal sector bare ventrally; infrasquamal 
| hairs absent; parafacials never completely haired.
