Canberra, 25 Jan. 1957, P. B. Carne, T.t. 2118, emerged from larva of Gonipterus sp.; Black Mtn Peninsula, Canberra, 30 Jan. 1970, H. E. Evans, T.t. 393.— New South Wales: nr. Queanbeyan, 10 Feb. 1955, S. J. Paramonov, T.t. 35.— Western Australia: Fitzroy Crossing, 19 Jul. 1968, P. Ferrar, T.t. 380.

A large, rather pale species, practically identical to A. perplexa sp. nov. (see below), but differing as follows:

Head. Occiput with mainly pale “scales”, usually at least a few in the first row of setae behind the postocular row.

Thorax. Median vitta sometimes absent. Presutural intra-alar seta absent on at least one side in about 50% of specimens.

Terminalia ( Figs 58–60 ). In lateral view syntergosternite 6–8 relatively long, gently sloping; surstylus falcate, with hooked tip; cercus with basal lobe not prominent, about as long as the remainder.

Distribution. Of specimens seen, all but one came from Canberra; the other (and quite typical) was from Western Australia.

Biology. Most specimens were taken at light, but one was reared from larvae of the weevil Gonipterus scutellatus.

Notes. Despite the strong external resemblance to several other species, the terminalia are quite different and the species is obviously a good one. It is dedicated to my colleague, friend, and noted dipterist, the late Dr K. R. Norris.
