Family Atracidae Hogg, 1901

Included genera: Atrax O. P.-Cambridge, 1877; Hadronyche L. Koch, 1873 ; Illawarra Gray, 2010 .

Diagnosis (modified from Gray, 2010). Atracidae can be distinguished from other mygalomorph spiders by the combination of the following characters: only 2 pairs of spinnerets, a relatively broad embolic shaft, large posterior sternal sigilla, maxillae with coniform anterior lobe, PLS relatively short, fovea a transverse groove.

Remarks. In his diagnosis for Atracinae (subsequently elevated to family status by Hedin et al., 2018), Gray (2010: 290) included the character “cheliceral retromargin with row of large teeth”. The absence of teeth on the cheliceral retromargin of H. nadgee sp. nov. requires removal of this feature from the diagnosis for family Atracidae .
