Austropsyche kaputar sp. nov.

( Figs 68–69 , 72, 77 , 90–91)

Material examined. Holotype ♂, New South Wales, Mt Kaputar NP, Bullawa Cr., 24.xi.1984, G. Hangay ( NMV [PT-1714]).

Paratypes, New South Wales: 2♂ 7♀, data as for holotype [PT-1713].

Diagnosis. Austropsyche kaputar shares with Au. bifurcata and Au. victoriana the form of wing venation, with the forewing median cell exceeding by about 1/3 the length of the discoidal cell and in male genitalia having endothecal spines subapically on the phallic apparatus; but uniquely, this species has the mesal process on the coxopodite of each gonopod stout, elongate, and arising within a 'collar' near the base of the coxopodite.

Description. Length of each forewing: ♂ 9.4–10.8 mm (n = 3), ♀ 11.5–12.2 mm (n = 7); wing venation ( Fig. 77 ) as in Au. bifurcata , forewing median cell elongate, length about 5x maximum width; filaments on abdominal segment V about length of segment.

Male. Abdominal reticulate-walled internal sacs elongate, greater than one segment length. Genitalia ( Figs 68– 69 , 90–91 ): Tergites IX and X partially fused, tergite X in dorsal view shallowly cleft at apex; gonopods each with coxopodite bearing relatively large, densely setose mesal process arising near base and extending almost to apex of coxopodite, in lateral view arising ventrally near base of coxopodite, apically acute; phallic apparatus with 2 pairs of sclerotised spines subapically.

Female. Terminal abdomen with sternite VIII divided to form 2 plates, plates broad based in ventral view, broadly rounded apicomesally, apicolateral angles sharply triangular.

Distribution. Known only from the type locality, approximately 50 km east of Narrabri, on the western side of the Great Dividing Range in north-eastern New South Wales.
