Key to the Genera of Micronectidae of Australia

1. Small, generally ovate micronectids, length 1.65–2.75; ground color light yellow to reddish-brown, hemelytral markings always present, patterning consisting of mottling, or broad, expanded darker areas, or somewhat linear shapes ( Figs. 1 , 4 , 8 , 12 ); hind margin of head acutely triangular; pronotum very short, anterior margin with distinctly produced carina, basal margin truncate; male left paramere glabrous ( Figs. 3d–e , 6a–c , 10a–c , 15a–d )................... Austronecta gen. nov. (pg. ###)

– Larger, generally elongate micronectids, length 1.79–4.54; ground color brown, hemelytral patterning absent or present as lineate stripes; hind margin of head rounded; pronotum well-produced, long, anterior margin weakly to non-carinate, basal margin rounded; male left paramere with scales in distal one-third, or scales absent and modified otherwise........................................................................................... Micronecta Kirkaldy (pg. ###)
