TACHINIDAE OF AUSTRALIA 33 



Key to Australian Genera of TRICHOPODINI 



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 Ti + 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 

 c;illi 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
