Key to adult males of Austropsyche Banks

1. Phallus bulbous distally, narrowly truncate and sclerotised apically; sharp, sclerotised, ventrally curving spine arising apicolaterally on abdominal segments IX/X, and second thread-like sclerotised process arising from internal apodeme ( Fig. 67 ); mesal process on coxopodite of each gonopod about half length of its harpago ( Figs 66–67 , 94 )...... Austropsyche morana sp. nov.

-. Phallus not bulbous distally, without sclerotised apex; abdominal segments IX/X with or without membranous plate or lobe apicolaterally, but without apicolateral sclerotised spine; mesal process on each coxopodite variable in length (e.g., Figs 52 , 59, 63)................................................................................................. 2

apical on coxopodite; without pair of slender, elongate, sclerotised spines as above (e.g., Figs 52 , 63–65), but with short sclerotised spines on phallus (e.g., Figs 53, 56 , 63–64, 87–88)....................................................... 5 4(3) Gonopods each with mesal process about 3/4 length of harpagone, slender, acute apically; small conical tubercle between mesal process and harpago ( Figs 59 , 92 )............................................. Austropsyche acuta sp. nov.

-. Gonopods each with mesal process no more than half length of harpagone, variably blunt or pointed apically; without small conical tubercle between mesal process and harpago ( Figs 61–62 , 93 ).................... Austropsyche ambigua sp. nov.

5(3) Gonopods each with mesal process on coxopodite short, irregular in shape; sclerotised spines on phallus in ventral view straight; in ventral view, small rounded plate visible dorsal to gonopods, in lateral view apicomedial margin slightly produced ( Figs 63–65 , 88–89 )........................................................ Austropsyche bifurcata (Kimmins)

-. Gonopods each with mesal process on coxopodite short, conical and apically acute in ventral view; sclerotised spines on phallus in ventral view curved; apex of phallus membranous, sometimes protruded; in ventral view membranous plates lateral to gonopods mesally produced posterad, in lateral view forming irregular midapicolateral lobe ( Figs 53–55 , 84–87)...................................................................................... Austropsyche victoriana Banks
