Austrogynacantha is a genus of dragonfly in the family Aeshnidae.

[4] Austrogynacantha heterogena, commonly known as the Australian duskhawker, is the only known species of this genus[5] which is found in Australia[6] and New Caledonia.

[7] Austrogynacantha heterogena is a medium-sized dragonfly, darkly coloured with bright green or yellow markings.

It is a vagrant, is active at dawn and dusk,[6] and inhabits still waters.

[8] The Australian duskhawker, Austrogynacantha heterogena, should not be confused with almost-similarly named Australasian duskhawker, Anaciaeschna jaspidea, a different species of Aeshnid dragonfly.
