*Genus Hemicordulia Selys, 1870

The larvae of each of H. australiae , H. flava and H. superba can be identified based on morphology ( Theischinger 2007a). Of the morpho-group H. intermedia and H. koomina only H. intermedia has a wide geographical range including northern, central and much of eastern Australia so that only identifications from the Pilbara area are doubtful. Of the morpho-group H. tau , H. continentalis and H. kalliste it appears that H. kalliste is the only species at, and restricted to, the extreme north of Australia, whereas H. tau is the only one occurring in Western Australia, central and most of southern Australia.
