Poustie ( WAM T70202, T74315– T 74316) . Etymology: This species is named for its occurrence in the montane regions of the Stirling Range National Park ( montanus , Latin, pertaining to mountains). Diagnosis: Atelomastix montana is similar to A. tumula , A. danksi and A. poustiei as the anterior gonopod sclerite a 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 a is only distally bifurcated with the medial process longer than the lateral process, and sclerite b tapers to a narrow point, not extending to sclerite c , with the basal process longer than wide. Description: Male ( holotype ). 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 a with swollen base that forms broad, concave area where pseudoflagellum emerges, and broad, curved distal hood; sub-distal edge of concave area of sclerite a with 3–6 setae (n=4); upper distal face of sclerite a with 12–14 (n=4) short blunt setae; pseudoflagellum long, elongate and partially obscured by broadened distal hood; sclerite b elongate and curved, tapering to a very narrow, curved, rounded tip, setae absent; basal process of sclerite b broad and triangular, 0.33 times the length of the main process; sclerite c slightly longer than sclerite b , 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 b instead group of setae where sclerites overlap, and group of 12–14 (n=4) short setae sub-basally on sclerite c ; 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 a 0.979 / 0.485 ( 1.024 / 0.476 ), setae 12 + 6 (12 + 4); sclerite b 0.431 (0.448), basal process of sclerite b 0.142 (0.176), setae 0 (0); sclerite c 0.787 (0.816), setae 10 (10) . Female . Similar to male, other than sexual characters, and slightly larger. Distribution and habitat: Atelomastix montana 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 ).
