*Genus Austroagrion Tillyard, 1913

The larva of A. exclamationis can confidently be identified. Based on morphology larvae from south-western Australia and South Australia can confidently be referred to A. cyane , larvae from south-eastern Australia to A. watsoni , and larvae from the Pilbara area in north-western Australia to A. pindrina ( Theischinger & Endersby 2009) . However, there is an overlap of A. cyane and A. watsoni in the extreme west of Victoria ( Richter 2014) . The diagnostic characters of Austroagrion (from Xanthagrion erythroneurum ) of the median caudal gill seem to work only for final instar larvae. More distinctly ringed antennae and a narrower labium usually distinguish younger Austroagrion larvae from Xanthagrion .
