Sclerite <i>b</i> is variable in shape but generally curved distally and shaped like a bird’s head. This species is similar to <i>A. melindae</i> and <i>A. culleni</i> but can be distinguished by the tapering distal tip of sclerite <i>c</i> that is rounded distally and can be symmetrical to slightly asymmetrical compared with the bifurcated, angular distal tip of <i>A. melindae.</i> It can be distinguished from <i>A. culleni</i> by the concavity on the interno-lateral side of the gonopod, and the curved hook tip of sclerite <i>b</i> compared with the broadened distal tip, internally placed concavity of sclerite <i>c</i>, and rounded tip of sclerite <i>b</i> in <i>A. culleni</i>. <b>Description:</b> <i>Male (holotype).</i> Colour: generally dark brown; legs, mouthparts, gonopods golden brown; prozonites brown to dark brown, metazonites golden brown in preserved specimens. Body: ca. 27 mm long and ca. 1.8 mm wide at collum. With 52 trunk segments, 93 pairs of legs, last 2 segments without legs. Head: with ca. 40 ocelli (Fig. 70), arranged in 5 rows (5: 7: 9: 9: 10). Gonopods: anterior gonopods (Figs. 125–127) lightly sclerotised, 2.4 times longer than broad; sclerite <i>a</i> with swollen base that forms broad, curved distal hood; upper distal face of sclerite <i>a</i> with 24–25 (n=2) short blunt setae; pseudoflagellum relatively short and partially visible beneath distal hood; sclerite <i>b</i> variable in shape but generally broad and curved distally forming a beak-like hook, with 4–8 (n=2) setae; basal process of sclerite <i>b</i> small and triangular, 0.05 times length of main process; sclerite <i>c</i> not bifurcate, with rounded distal tip varying in shape from symmetrical to slightly asymetrical, with 6–7 setae (n=2); one sub-basal setae present where sclerites overlap and group of 12 short setae sub-basally on sclerite <i>c</i>; posterior gonopods inconspicuous, small, with several small setae on interno-lateral face of each gonopod. Dimensions (mm): holotype male (paratype male, WAM T 73957): length ca. 27 (31), width ca. 1.8 (1.9); L/W=14.7 (16.9); sclerite <i>a</i> 1.168 / 0.480 (1.2/0.576), setae 24 (25); sclerite <i>b</i> 0.426 (0.435), basal process of sclerite <i>b</i> 0.058 (0.032), setae 8 (4); sclerite <i>c</i> 0.736 (0.8), setae 7 (6). <i>Female</i>. Similar to male, other than sexual characters, and slightly larger. <b>Distribution and habitat:</b> This species has been collected from a number of localities in leaf litter, in creek beds and under rocks in the coastal granite outcrops of the Fitzgerald River National Park and the Ravensthorpe Ranges (Fig. 9).
