TACHINIDAE OF AUSTRALIA 97 
The key to Australian genera here given is, however, only a preliminary one. 
The Australian fauna contains many undescribed forms that will have to be fitted 
into the Eryciini when they are named. Eryciine forms are rather well developed 
in Australia, and most of the genera are endemic; some essentially extra-limital 
genera (such as Aplomya and Erythrocera) occur, and it is likely that other 
Oriento-Papuan genera (such as Aneogmena) will eventually be found in Queensland. 
Some of the Australian eryciines, like Awstronilea, are extraordinarily similar to 
Palaearctic counterparts, and the Tasmanian fauna includes several undescribed 
forms that belong in the subgroup Baumhaueriina (a segregate occurring elsewhere 
in the Palaearctic Region and southern Africa); the Tasmanian forms referred to 
are recognized by the possession in the females of a pair of outwardly-directed 
prevertical setae, and are the only Australian Goniinae known that possess 
prevertical setae (except for the species of Spoggosia). 
It may be useful to note that all the Australian eryciines so far known have the 
lower surface of the second costal sector bare, and all have at least three setae on 
the humeral callus, these standing more or less in a straight line (there are no 
Australian eryciines, so far known at least, that have three humeral setae set in a 
well defined triangle: three humerals in a triangle occur in Walker’s type of 
Tachina calliphon, which is an eryciine, but there is uncertainty as to whether 
this specimen is genuinely Australian). 
The genus Bactromyiella is very difficult to place satisfactorily but is here 
retained in the Eryciini; the small pra seta suggests that it ought possibly to be 
placed in the Blondeliini, and the general facies and haired barette suggest that it 
would not be inappropriate to treat it as a winthemiine. 
The eryciine genera Aneogmena and Dolichocolon are included in the following 
key as they occur in New Guinea, and may possibly occur in Australia. 
Kry To AUSTRALIAN GENERA OF ERYCIINI 
1 Wing with cell R; closed well before the wing margin and long-petiolate. Last 
section of vein Cu, conspicuously longer than cross-vein m—cu. Two presutural 
dorsocentral (prst dc) setae (very weak third setula sometimes developed between 
two main setae). Apical scutellar setae directed almost straight upwards 
PHOROCEROSTOMA Malloch 
-— Wing with cell R; open at wing margin or just closed at the margin (not at all 
petiolate). Last section of vein Cu, shorter than, or subequal in length to, 
m-—cu. Three presutural dorsocentral setae (except in Aneogmena and Evythrocera 
in which normally two). Apical setae of scutellum horizontal or directed 
obliquely upwards, sometimes absent. . . : ; : : : : 2 
2 Mid tibia without a submedian v seta. Barette haired along its length (sparsely 
in 9). Sexes strongly dimorphic in colour and pattern: ¢ with thorax and first 
abdominal segment black and remainder of abdomen bright golden orange or 
orange-red; Q black with pleural regions, two fasciae on mesonotum, apex of 
scutellum, and transverse band on each abdominal tergite 3-5, greyish yellow 
to bright golden ; : BACTROMYIELLA Mesnil 
-— Mid tibia with a submedian v ‘seta. Barette bare or with only one or very few 
hairs anteriorly (more extensively haired in Tevetvophova). Sexes not strongly 
dimorphic in colour or pattern, never as described above . : : ‘ 3
