Types. Holotype male in ANIC no. 29-029223, Black Mtn, ACT, light trap, 17 Mar. 1958, IFBC, terminalia in tube 141. Paratypes: 11 males, as for holotype but 21 Jan. 1955, T.t. 142; 26 Jan. 1955, T.t. 161; 26 Feb. 1955, T.t. 49; 14 Jan. 1957, T.t. 50; 7 Jan. 1964, T.t. 123; 21 Jun. 1965, T.t. 2180; 16 Feb. 1965, T.t. 130; 3 Feb. 1967; 31 Dec. 1967; 16 Jan. 1968; 22 Apr. 1968.— New South Wales: Talmalmo, nr Albury, Feb. 1962, Slaney, T.t. 291, ex weevil larva.— Western Australia: 19 mi W of Watheroo, 15 Apr. 1968, IFBC & MSU, T.t. 322.
Male. Generally resembling the pale form of A. rufifacies, differing as follows:
Head. Eye with very sparse hairing or (usually) none; postocellar setae 2–4; upper occiput with few or (usually) no dark hairs behind the postocular row.
Thorax. Median dark vitta usually well developed, before and behind suture. Intrapostalars clearly differentiated, often stouter than usual in congeners; proepisternal hairs pale.
Legs. Foretibia with preapical ad usually 0.5–0.6 length of adjacent d bristle. Tibiae usually paler than femora, but difference not very striking. Hindtibia with shortest Pd1 in the whole group: Pd1/Sdd 0.5–0.7, mean 0.62.
Abdomen. Syntergite 1+2 with 2–4 differentiated submedian marginals; tergite 3 with submedian marginals at most slightly differentiated.
Terminalia ( Figs 50, 51 View Figs 50, 51 ). Surstyli characteristically expanded, leaf-like, with rounded apex and many short, stout bristles on both surfaces; cerci very characteristically curved in anterior direction and with substantial apicointernal teeth.
Female. Recognized on the basis of a single specimen apparently co-reared with the above male from Talmalmo. Differs from male in usual sexual characters.
Terminalia ( Fig. 86 View Figs 82–86 ). Tergite 6 as in A. dayi; sternite 6 with straight posterior margin, no median projection; tergite 7 with apical parallel pieces rather fine, completely separated from the strongly sclerotized basal pieces; sternite 7 more
.
finely developed than in two preceding species, relatively broad and not so strongly downcurved; membrane of tergites 7 and 8 finely spiculate, individual spicules resolved only with high power, but segments 6–7 with intersegmental membrane coarsely and conspicuously spiculate.
Distribution. Qld, NSW, ACT, and WA, and no doubt occurs in Vic. and SA as well.
Biology. As for the previous species, a single co-reared pair from a weevil larva (presumably Gonipterus scutellatus) has enabled correlation of the sexes. Other specimens were taken at light.
Notes. The species is named for my colleague, the late Dr Ian Common, whose light traps contributed so much of the material studied here.
