Key to males of the genus Austroplebeia 

Remarks. Males of A. australis  , A. cassiae  and A. magna  sp. nov. are very difficult to distinguish in isolation. Their colouration and structural characteristics overlap much more than those of the workers (compare Figs 7View FIGURE 7, 8View FIGURE 8). A high quality microscope is needed to see the differences in the mesepisternum plumose hair given in the key. However, these were the most reliable distinctions found between the males of these species in this analysis.

1. Scutellum maculation limited to a very narrow cream band on posterior rim (Thorax Grade 18, Figs 5View FIGURE 5, 25View FIGURE 25 c). Frons and mesepisternum with simple hair ( Figs 23View FIGURE 23 a, 25 c). S 6 median body narrow ( Fig. 20View FIGURE 20 k). Base of penis valve relatively long and tapered ( Fig. 21View FIGURE 21 a) Currently known only from northeastern QLD ( Fig. 28View FIGURE 28 a).............................. A. cincta (Mocsáry) 

- Scutellum with a prominent dorsal cream or yellow maculation (Thorax Grades 5–14, Figs 5View FIGURE 5, 25View FIGURE 25 d). Frons and mesepisternum with plumose and simple hair ( Figs 23View FIGURE 23 b –f, 25 d). S 6 median body broad ( Figs 20View FIGURE 20 l –o). Base of penis valve relatively short and broad ( Figs 21View FIGURE 21 b –c). Distribution: WA, NT, QLD, NSW...................................................... 2

2 (1). Small bees, head width <1.60 mm ( Fig. 14View FIGURE 14), forewing including tegula ≤ 3.7 mm. Gonostylus tip with distinct subapical curve ( Figs 21View FIGURE 21 b, d). S 6 median body tapering. S 5 apical margin with protruding narrow lobes ( Figs 20View FIGURE 20 l, h). HBW 0.18–0.22 mm ( Fig. 13View FIGURE 13). Distribution: WA, NT ( Fig. 28View FIGURE 28 b)............................................. A. essingtoni (Cockerell) 

- Larger bees, head width> 1.65 mm ( Fig. 14View FIGURE 14), forewing including tegula ≥ 3.8 mm. Gonostylus gently curved ( Figs 21View FIGURE 21 c, e). S 6 median body parallel sided or with slight median constriction. S 5 apical margin smooth or slightly curved ( Figs 20View FIGURE 20 m –o, i –j). HBW 0.22–0.29 mm ( Fig. 13View FIGURE 13). Distribution: WA, NT, QLD, NSW.............................................. 3

3 (2). Mesepisternum plumose hairs narrow and feather-like, with short closely set barbs ( Fig. 25View FIGURE 25 d, f). Distribution: QLD ( Fig. 28View FIGURE 28 d)................................................................................... A. cassiae (Cockerell) 

- Mesepisternum plumose hairs broad or irregular in shape, with longer sparser barbs ( Figs 25View FIGURE 25 e, g). Distribution: WA, NT, QLD, NSW.............................................................................................. 4

4 (3). Mesepisternum plumose hairs usually with long evenly spaced barbs and a broad triangular shape ( Fig. 25View FIGURE 25 e). Distribution: WA, NT, QLD, NSW ( Fig. 28View FIGURE 28 c).............................................................. A. australis (Friese) 

- Mesepisternum plumose hairs with long barbs at various angles and irregular in shape ( Fig. 25View FIGURE 25 g). Distribution: NT and far northwestern QLD ( Fig. 28View FIGURE 28 d)............................................................. A. magna  sp. nov.
