This species can be distinguished by the distinctly angular shaped sclerite <i>b</i> and very elongate basal process that extends behind the main process of the male gonopod. Sclerite <i>c</i> is not bifurcate, is relatively straight, and shorter than sclerite <i>b</i>. <b>Description:</b> <i>Male (holotype).</i> Colour (Fig. 3): live specimens with black to dark brown segments, head and legs with bright yellow-orange bands; prozonites dark brown, metazonites brown to bright yellow-orange in preserved specimens. Body: ca. 56 mm long and ca. 3 mm wide at collum. With 65 trunk segments, 117 pairs of legs, last 2 segments without legs. Head: with ca. 46 ocelli (Fig. 73), arranged in 6 rows (3: 6: 7: 10: 8: 11). Gonopods: anterior gonopods (Figs. 132–135) heavily sclerotised, 2.7 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 18–20 (n=3) short blunt setae; pseudoflagellum short, broad, and entirely visible on externo-lateral side of gonopod but not visible on interno-lateral side, where it is concealed within distal hood; sclerite <i>b</i> broad, angular, forming a blunt tip distally, with 4 erect setae (n=3) on sub-distal edge; basal process of sclerite <i>b</i> very long and elongate, 0.16 times the length of the main process; sclerite <i>c</i> shorter than sclerite <i>b</i>, not bifurcate, tapering to blunt tip, with 1–3 medial seta and 7–9 setae sub-distally on broad internal face (n=3); one sub-basal setae present where sclerites overlap and group of 13 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 T74311): length ca. 56 (61), width ca. 3 (3), L/ W=18.7 (20.3); sclerite <i>a</i> 1.656 / 0.608 (1.704 / 0.694), setae 18 (20); sclerite <i>b</i> 0.701 (0.733), basal process of sclerite <i>b</i> 0.264 (0.288), setae 4 (4); sclerite <i>c</i> 1.088 (1.184), setae 1+9 (3+7). <i>Female</i>. Similar to male, other than sexual characters, and slightly larger. <b>Distribution and habitat:</b> This species is only known from The Cascades at Bluff Knoll and the south face of Pyungoorup Peak in Stirling Range National Park (Fig. 5). The surrounding vegetation is dominated by sparsely growing jarrah (<i>Eucalyptus marginata</i>) and marri (<i>Corymbia calophylla</i>).
