Tillyard (1916a), Albrook (1979), both as A. longissima ; Theischinger (1982, 2002, 2012); Hawking (1986); Hawking & Theischinger (1999); Gooderham & Tsyrlin (2002); Theischinger & Hawking (2003, 2006); Peters & Theischinger (2007); Theischinger & Endersby (2009).

*Genus Austroaeschna , Subgenus Petersaeschna Theischinger, 2012

Distributions can at least in part support identification of four of the five species. Tropical Queensland north of Paluma-Eungella gap: A. speciosa ; inland Queensland: A. pinheyi ; Cooloola region, Stradbroke Island and Fraser Island: A. cooloola ; most of eastern Queensland south of Paluma-Eungella gap, eastern New South Wales, Victoria, Tasmania, South Australia: A. unicornis . There is no need for confirming identification of A. inermis on geography (Theischinger 2002, 2012).
