TACHINIDAE OF AUSTRALIA 33 
Key To AUSTRALIAN GENERA OF TRICHOPODINI 
1 Abdomen uniformly orange or yellow-orange, at most only a little darkened apically. 
Sides of the abdomen subparallel or very slightly convex (Text-fig. 91). Pre-alar 
seta absent. One prst dc seta. Scutum with the yellow pollinose transverse 
band extending on to the postalar calli and supra-alar areas 
PENTATOMOPHAGA de Meijere 
— Abdomen pallid luteous yellow with a fine dark median line on the basal half and 
mainly dark brown or blackish on the posterior half. Shape of abdomen distinctly 
a little clavate, narrower on Tr + 2 and basal half of T3 than on succeeding 
segments (Text-fig. 90). Small pra seta present. At least two prst dc setae 
clearly differentiated. Scutum with the yellow pollinose transverse band more 
or less confined to the prescutellar area, not extending laterally on to the postalar 
calli and supra-alar areas ; ‘ : ; : . SARALBA Walker 
Tribe PHASIINI 
This tribe is nearly cosmopolitan, but in contrast to the Trichopodini (to which 
it is undoubtedly very closely related) tends to be best represented in the temperate 
and subtropical parts of the world rather than in the tropics, though many truly 
tropical species are known. The tribe is represented in New Zealand, where three 
species of the so-called genus Campbellia Miller occur; this genus is treated as valid 
by Dugdale (1969), but appears to be indistinguishable from Mormonomyia Brauer 
& Bergenstamm, a subgenus of Alophora s.l. that is widespread in Africa and 
Australia. 
The Australian fauna of Phasiini is comprised mainly of species (many certainly 
undescribed) of the genus Alophora R.-D. This large genus occurs in both Old 
and New Worlds and has been split by various authors into many so-called genera 
that can at best be only very poorly defined (and are found to be largely inter- 
connected by intermediate forms if the world fauna is studied). In addition to 
being variously split the genus in the wide sense has often been known as Hyalomyia 
(an incorrect spelling of Hyalomya), and Malloch in his various papers on the 
Australian Tachinidae referred all of the described species of the complex to 
Hyalomya. The names Alophora and Hyalomya were proposed by Robineau- 
Desvoidy (1830) in the same work, and usage has been rather equally divided in 
the taxonomic history of the group; recent works on the Eurasian and African 
Phasiini have, however, mainly adopted the name Alophora for the genus, with the 
name Hyalomya applied to one of the constituent subgenera where named subgenera 
are recognized, and this course is here followed in accordance with the recent work 
of Draber-Monko (1965). In her revision of the Palaearctic species Draber-Monko 
(op. cit.) treats Alophora in a broad sense and recognizes seven segregates in the 
Palaearctic fauna as named subgenera; this approach is by far the most sensible 
that can be adopted in trying to deal with the difficult Alophora complex, and an 
exactly comparable approach is here adopted for dealing with the Australian 
fauna (which breaks into a number of moderately distinct entities taxonomically 
equivalent to those treated as subgenera by Draber-Monko). At least two of the 
Palaearctic subgenera, viz. Alophorella and Hyalomya, can be recognized in the
