Australian fauna, and two other subgenera may be represented by species here 
left subgenerically unplaced (these are hippobosca Paramonoy whose characters 
are very close to those of the Palaearctic subgenus Phorantha Rondani, and 
nigrisguama Malloch that has characters similar to those of subgenus Brumptallophora 
Dupuis). Several of the Australian species, however, do not fit any of the Palaearctic 
segregates, but instead are assignable to Mormonomyia Brauer & Bergenstamm, 
a subgenus of Alophora s.l. until now considered to be entirely African. A careful 
comparison of these Australian species with the African species (including the 
type-species of Mormonomyia) has shown a complete concordance in the essential 
characters, and it is here considered that the Australian species must be placed as 
consubgeneric with the African ones; the subgeneric name is therefore applicable 
to these Australian species. (Here it may usefully be noted that comparison of 
the New Zealand genus Campbellia Miller with Mormonomyia, made whilst comparing 
Australian and African species, has shown no differences that can be considered 
of any nomenclatorial consequence and the name Campbellia ought almost certainly 
to be placed in synonymy with Alophora (Mormonomyia).) 
In addition to Alophora s.l. the Australian Phasiini includes the genera Efftayloria 
and Besserioides. The former occurs also in New Guinea and is closely allied to 
Alophorophasia Townsend (synonym: Kosempomyia Villeneuve), having the lower 
surfaces of the femora similarly armed with rows of short stubby spinules. 
Besserioides is entirely Australian on present evidence, but is evidently very closely 
allied to the monotypic Ethiopian genus Bogosiella Villeneuve (from which it differs 
by having the frons equally wide in both sexes and by having the posterior spiracles 
of the puparium on prolonged paired bosses). 
The main external features of Phasiini are as follows. Head holoptic or dichoptic, some 
eye facets of both sexes enlarged in some forms; 2 without proclinate orbital setae; face 
without a median keel; ocellar setae proclinate or absent; antennae usually short or very 
short, if moderately long (e.g. Alophorophasia alata Townsend) nevertheless falling well short 
of epistomal margin; palpi present, sometimes weak; humeral callus with o—2 setae; acy setae 
usually o + 1 (hair-like); de setae variable (often hair-like), commonly 1 + 2 (sometimes 3) 
post dc or only one distinct; one sa seta; one post ia seta or none; usually 1 + 1 oro + 1 sépl 
setae, rarely 2 + 1; infrasquamal hairs present or absent; scutellum with one (apical) or 
two (basal and apical) pairs of marginal setae, rarely weak third pair, without discal setae; 
scutellum sometimes rather bullate and postscutellum often much produced posteriorly and 
then visible beyond the scutellum when seen from above; wings either of normal form or 
(very commonly) much produced in the anal region (especially in @) so that they are very 
broad basally and short; wings often wholly or partially infuscate or yellowish or orange 
basally; second costal sector bare ventrally (first sector often also bare as well); basal node 
of Ry; usually with one or two very minute hairs, sometimes bare; bend of M forming an 
even curve without trace of appendix; cell R; usually closed well before the wing margin 
and petiolate, occasionally just open or closed at the margin (closed and petiolate in known 
Australian forms); last section of Cu, very short, less than half as long as m—cu (sometimes 
postero-apical corner of discal cell virtually reaching the margin of the wing); lower calypter 
very broad posteriorly, hind margin nearly straight but outer posterior corner sometimes 
strongly produced; legs weakly bristled in most forms or devoid of definite setae, sometimes 
with a few stubby setae or combs of stubby setulae ventrally on the femora; tibiae often 
strongly curved or appearing so, hind tibia without scale fringes; hind tibia without pd 
preapical seta or pu apical seta; hind coxae close to or at least not very remote from the
