Distribution and natural history
Aname blackdownensis occurs on the Blackdown Tableland in central-eastern Queensland, in the Brigalow Belt South bioregion, located between Emerald and Rockhampton (Fig. 6). It constructs an open, silk-lined burrow without silk outside of the entrance, often on an angle, and with a hidden secondary ‘wishbone’ entrance (Fig. 6).
