Diagnosis. Male similar to that of Austropsyche bifurcata   in having 2 pairs of endothecal spines associated with the phallic apparatus, and only a very short sub-apical mesal spur on the coxopodite, but distinguished by the strongly ventrally directed spines subapically on the phallus; conical subapicomesal process on the coxopodite; in ventral view by the variably shaped basomesal lobes ventral to the phallic apparatus and dorsal to the gonopods (phallic guides of Ross & Morse unpublished MS), in lateral view visible as rather stout, tapered or rounded apicomesal lobes on abdominal sternite IX; without deep, elongate, sclerotised spines as seen in Au. ambigua   and Au. acuta   .

Description. Length of each forewing: ♂ 9.4–10.8 mm (n = 15), ♀ 13.1–14.1 mm (n = 7); venation as for Au. bifurcata   ( Fig. 49 View FIGURES 49–58 ).

Male. Abdomen ( Fig. 82 View FIGURES 70–83 ) reticulate-walled internal sacs with pair on segment VI length of 2 segments, those on segment VII about 1.5x length of segment; lateral filaments on segment V elongate, almost length of segment. Genitalia ( Figs 52–56 View FIGURES 49–58 , 84–87): In lateral view abdominal sternite IX with stout lobe protruding distally at each apicolateral angle, lobe conical, projected ventrad; tergite X short; gonopods each with coxopodite expanded towards apex, subapicomesally short conical process, harpago about half length of coxopodite, constricted in proximal third and distally curved mesad; phallic apparatus laterally with pair of short sclerotised spines subapically, without upper internal rods, phallotrema elongate, sclerotised dorsally.

Female ( Fig. 98 View FIGURES 84–101 ). Abdominal sternite VIII in form of pair of subtriangular ventral plates, apicolateral angles very slightly produced distally; segment IX basally with transverse opening to sclerotic cavity.

Distribution. Widespread and quite commonly collected in Victoria from the Grampians to the central ranges.

Remarks. Considerable variation is seen in the male genitalia of this species. The apicolateral lobes on abdominal segment IX are variable in shape and length ( Figs 52, 55 View FIGURES 49–58 , 84, 86), some in ventral view being almost truncate apically, some with a concavity on the apex, and some with the mesal margin extended, digitiform; the mesal lobe on each coxopodite sometimes is scarcely developed; and in preserved specimens the phallotrema may or may not be extended. The form appears to be consistent in samples, but much more study is needed to evaluate the extent of separation of populations. For the present, all are assigned to Au. victoriana   .
