Poustie (WAM T70202, T74315 – T 74316). <b>Etymology:</b> This species is named for its occurrence in the montane regions of the Stirling Range National Park (<i>montanus</i>, Latin, pertaining to mountains). <b>Diagnosis:</b> <i>Atelomastix montana</i> is similar to <i>A. tumula</i>, <i>A. danksi</i> and <i>A. poustiei</i> as the anterior gonopod sclerite <i>a</i> is broad and concave sub-medially enveloping an elongate flagellum beneath a broad distal hood. However, it can be distinguished from other species because sclerite <i>a</i> is only distally bifurcated with the medial process longer than the lateral process, and sclerite <i>b</i> tapers to a narrow point, not extending to sclerite <i>c</i>, with the basal process longer than wide. <b>Description:</b> <i>Male (holotype).</i> Colour (Fig. 1): head, collum, anal segment dark brown, ozopores and legs golden-brown, prozonites blue grey, metazonites dark brown to grey in preserved specimens. Body: ca. 18 mm long and ca. 1.6 mm wide at collum. With 51 trunk segments, 91 pairs of legs, last 2 segments without legs. Head: with numerous ocelli (Fig. 66), ca. 29, in 4 rows (5: 6: 8: 10). Gonopods: anterior gonopods (Figs. 114, 115) very large, heavily sclerotised and complex in structure, 2.19 times longer than broad; sclerite <i>a</i> with swollen base that forms broad, concave area where pseudoflagellum emerges, and broad, curved distal hood; sub-distal edge of concave area of sclerite <i>a</i> with 3–6 setae (n=4); upper distal face of sclerite <i>a</i> with 12–14 (n=4) short blunt setae; pseudoflagellum long, elongate and partially obscured by broadened distal hood; sclerite <i>b</i> elongate and curved, tapering to a very narrow, curved, rounded tip, setae absent; basal process of sclerite <i>b</i> broad and triangular, 0.33 times the length of the main process; sclerite <i>c</i> slightly longer than sclerite <i>b</i>, broad and slightly concave medially, slightly tapering to a blunt, concave tip, with 6–10 setae (n=4) on internal concave face; with 1 seta on sub-basal edge of sclerite <i>b</i> instead group of setae where sclerites overlap, and group of 12–14 (n=4) 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 69804): length ca. 18, width ca. 1.6, L/W=11.2; sclerite <i>a</i> 0.979 / 0.485 (1.024 / 0.476), setae 12 + 6 (12 + 4); sclerite <i>b</i> 0.431 (0.448), basal process of sclerite <i>b</i> 0.142 (0.176), setae 0 (0); sclerite <i>c</i> 0.787 (0.816), setae 10 (10). <i>Female</i>. Similar to male, other than sexual characters, and slightly larger. <b>Distribution and habitat:</b> <i>Atelomastix montana</i> has been found at a number of sites in the eastern part of Stirling Range National Park, including Pyungoorup Peak, near Coyanarup Peak, and along the South Isongerup Track (Fig. 6).
