TACHINIDAE OF AUSTRALIA 
holoptic (although eyes sometimes very strongly approximated and frons then 
very reduced), facets not obviously enlarged (except in Palpostomatini) 
Epistomal region of the head prominent, visible in profile projecting in front oF 
the vibrissae (sometimes head strongly subnasute) (Text-figs 41-46). Vibrissae 
inserted at a level well above the epistomal margin (only slightly above in some 
Leskiini). Abdominal sternites at least partially exposed between the ventral 
ends of the tergites (except in Leskiini) (as in Text-fig. 20) : : : 
Epistomal region of the head not prominently projecting, invisible in profile 
(Text-figs 32-38). Vibrissae inserted about on a level with the epistomal margin 
(undeveloped in some forms). Abdominal sternites concealed by the pte oe 
ends of the tergites (except in Myiotrixini) 
Abdominal sternites concealed by overlapping termite dads ree meet in aaa 
venter). Scutellum with two pairs of marginal setae (basals and subapicals), 
without apical setae (except in Demoticoides which has apical setae in addition). 
Humeral callus usually with two or three setae : : LESKIINI (p. 
Abdominal sternites at least partially exposed, ventral ends of the tergites not 
meeting in the mid-venter. Scutellum with three or more pairs of marginal 
setae (including a strong crossed apical pair). Humeral callus with fous or 
more setae . : : : : 
Hind coxa with long fine hair on the posterodorsal surface. Eyes bare. Para- 
facials haired. Four post dc setae. : . TACHININI (p. 
Hind coxa bare on the posterodorsal surface. Eyes haired, or if bare (Amphitropesa 
and Neximyia) then parafacials also bare. Parafacials bare or haired. Three 
or four post dc setae : : ; : : ; : : 
Hind tibia without a pu apical seta. Two post ia setae (weak third present in 
Australotachina). Postabdomen of ¢ very large, tergites 6 and 7 + 8 forming 
an exposed vertical declivity at end of the abdomen. Scutellum with three 
pairs of marginal setae (except Austyvalotachina with four). Bend of vein M 
without an M, fold or spur-like appendix. Mid tibia without a submedian v 
seta in g, with such seta in. Parafacials bare. . PARERIGONINI (p. 
Hind tibia with a pv apical seta (except in Amphitropesa). Three post ia setae. 
Postabdomen of ¢ not of this form, tergites 6 and 7 + 8 not externally visible 
or only T7 + 8 just visible when hypopygium in situ. Scutellum with four or 
more pairs of marginal setae. Bend of vein M usually with a trace of an M, 
appendix or fold. Mid tibia of both sexes with a submedian v seta. Parafacials 
bare or haired 
Palpi very reduced, often minute or nitaally absent frecy much less than half as 
long as the mentum). Parafacials haired (except in Linnaemya). Eyes densely 
haired. Three post dc setae . : ; LINNAEMYINI (p. 
Palpi moderately or fully developed (at least half as ; long as the mentum of the 
proboscis). Parafacials bare. Eyes bare or haired. Three or four post dc setae 
ERNESTIINI (p. 
Sternites of the abdomen fully exposed. Vibrissae absent. Head profile as in 
Text-fig. 40. Lower ends of the facial ridges expanded into a pair of broad 
flattened and rather evenly haired facialia, and the epistome reduced to a long 
narrow strip between the facialia connecting the oral margin directly with the 
face in the same plane. Scutellum with two pairs of marginal setae (basals and 
subapicals), without apical setae . : : MYIOTRIXINI (p. 
Abdominal sternites concealed by overlapping ventral ends of the tergites (which 
meet in the mid-line of the venter). Vibrissae present (but sometimes weakly 
differentiated from the peristomal setae, especially in Palpostomatini). Head 
profile not as in Text-fig. 40. Facial ridges and epistome of different form. 
Scutellum usually with at least three pairs of marginal setae (two pairs only 
in Palpostomatini and some Minthoini) .
