TACHINIDAE OF AUSTRALIA 83 



Eophyllophila Townsend and Prodegeeria Brauer & Bergenstamm certainly occur 

 in the territory and may perhaps be found ultimately in Queensland. 



The genus Bactromyiella is very anomalous, but may perhaps be a blondeliine. 

 It has a small pra seta (smaller than the first post ia seta) and the bend of vein M 

 is evenly rounded as in typical Blondeliini, but the subapical scutellar setae are 

 parallel (not strongly divergent as is usual in blondeliines) ; the facies of Bactromyiella 

 is not especially blondeliine, but is more that of a winthemiine or eryciine. The 

 genus is kept tentatively in the Eryciini but is included also in the following key 

 to blondeliine genera. 



Key to Australian Genera of BLONDELIINI 



1 Mid tibia without a submedian v seta ........ 2 



- Mid tibia with a submedian v seta ......... 3

and with apical setae. Intermediate abdominal tergites without discal setae. 

 (J with velvety black thorax contrasting with bright orange or orange-red abdomen 

 (except Ti + 2 black) . . . [BACTROMYIELLA Mesnil, tribe Eryciini] 



- 2 + 3 dc setae. Prosternum bare. Scutellum with widely diverging subapical 



setae and without apical setae. Intermediate abdominal tergites with strong 

 erect discal setae. $ without such coloration . TRIGONOSPILA Pokorny 



3 2 + 2 dc setae (sometimes a very small additional post dc setula between the two 



main setae). Second supra-alar seta absent. Humeral callus with two setae. 

 Wing with distance on vein M from the bend to m-cu as great as that between 

 m-cu and r-m. Basal node of R i+b bare or with one minute hair. Two 

 sternopleural setae. Abdomen with Ti + 2 not excavate to its hind margin . 4 



More than 2 + 2 dc setae (2 + 3 or 3 + 3 or 3 + 4, occasionally 2+4). Second 

 supra-alar seta present. Humeral callus with three or more setae. Wing with 

 distance on vein M from the bend to m-cu conspicuously less than that from 

 m-cu to r-m. Basal node of R i+i with at least two hairs or setulae. Two or 

 three sternopleural setae. Abdomen with Ti + 2 excavate to its hind margin 

 (except in Lixophaga and Lecanipa) ........ 5 



4 Propleuron bare. £ with one pair of strong erect discal setae on each abdominal 



tergite from T3 to T5, 9 without abdominal discal setae. <§ without proclinate 

 orbital setae. § with ovipositor in form of a long strong downcurved hook easily 

 seen in profile. 9 hind coxa with apicoventral setae modified into short blunt 

 black pegs MEDINODEXIA Townsend 



- Propleuron sparsely haired. Both sexes without abdominal discal setae. $ with 



two pairs of proclinate orbital setae (like the §). $ with very short broad flattened 

 ovipositor that is not visible in profile. £ hirid coxa with apicoventral setae not 

 so modified MONOLEPTOPHAGA Baranov 



5 Propleuron bare. Vibrissae inserted about on a level with the epistomal margin. 



Parafacials bare (except in Pareupogona). Infrasquamal hairs sometimes 

 present ............. 6 



- Propleuron haired. Vibrissae usually inserted at a level distinctly above the 



epistomal margin. Parafacials usually entirely haired or haired at upper ends, 

 seldom entirely bare. Infrasquamal hairs absent ...... 10 



6 Fore tibia with two pv setae. Intermediate abdominal tergites with discal setae. 



Second costal sector bare ventrally. Hind tibia without a pd preapical seta. 

 Humeral callus with the three main setae standing in a straight line (except in 

 Lecanipa). g without proclinate orbital setae ...... 7 



- Fore tibia with one pv seta. Intermediate abdominal tergites without discal
