Key to males of Australian Amobia

1. Fronto-orbital and parafacial plates with silver microtomentum, upper mouthedge and gena with golden microtomentum ( Fig. 6B, D, G ); notopleuron with a distinct area of golden microtomentum ( Fig. 6A ) .................................................................................................. A. (s. str.) serpenta sp. nov.

– Fronto-orbital plate and parafacial plate both with golden or dull yellow microtomentum; gena with grey or golden microtomentum ( Figs 2B, D, G , 4B, D, G ); notopleuron without golden microtomentum ( Fig. 2 A–B) ............................................................................................................. 2

2. Fronto-orbital plate with dull yellow microtomentum ( Fig. 2 A–B, G); basicosta brown; male terminalia: cerci in lateral view broad in basal and distal 0.4 with distinct narrowing in middle 0.2 ( Fig. 3B ); in posterior view cerci straight and not curved away from one another ( Fig. 3A ) .................................................................................... A. (s. str.) auriceps ( Baranov, 1935)

– Fronto-orbital plate with bright golden microtomentum ( Fig. 4 A–B, G); basicosta yellow-brown; male terminalia: cerci in lateral view gradually tapering from base to tip ( Fig. 5B, D ); in posterior view cerci weakly curved away from one another ( Fig. 5A, C ).... A. (s. str.) burnsi ( Malloch, 1930)
