description: <i>Atelomastix sarahae</i>, sp. nov. Figs. 9, 72, 130, 131. <b>Type material:</b> AUSTRALIA: Western Australia: holotype male, Mount Arid, Cape Arid National Park, south side near summit, 33°54’45”S, 123°13’01”E, hand collected under rocks, 5 June 2007, M.L. Moir, M.C. Leng (WAM T 85863). Paratypes: Mount Arid, Cape Arid National Park: 9 males, 25 females, collected with holotype (WAM T 80671); 38 males, 34 females, collected with holotype (WAM T 80674). <b>Etymology:</b> The specific epithet is a patronym in honour of Sarah Comer who has collected numerous specimens of <i>Atelomastix</i> in southwestern Western Australia. <b>Diagnosis:</b> The male gonopod morphology of <i>Atelomastix sarahae</i> differs from other species as sclerite <i>c</i> is not bifurcated but slightly curved distally with an interno-lateral concavity that extends to the sub-distal tip of the sclerite. Sclerite <i>b</i> is much higher than the tip of sclerite <i>c</i>, extends to the edge of sclerite <i>c</i> and curves distally to a pointed tip. <b>Description:</b> <i>Male (holotype).</i> Colour: generally chocolate-brown with mottled blue-grey; legs, antennae, mouthparts, and gonopods golden brown; ozopores distinct and golden brown; prozonites chocolate brown, metazonites mottled blue-grey to brown in preserved specimens. Body: ca. 27 mm long and ca. 1.7 mm wide at collum. With 56 trunk segments, 101 pairs of legs, last 2 segments without legs. Head: with ca. 45 ocelli (Fig. 72), arranged in 7 rows (1: 4: 7: 9: 8: 8: 8). Gonopods: anterior gonopods (Figs. 72, 130, 131) heavily sclerotised, 1.9–2.2 mm (n=2) 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 28–31 (n=2) short blunt setae; pseudoflagellum relatively short and partially visible beneath broad distal hood; sclerite <i>b</i> relatively broad, curved subdistally, tapering sharply to a pointed curved tip, with 9–14 (n=2) short setae; basal process of sclerite <i>b</i> short and triangular, 0.02–0.03 (n=2) times length of main process; sclerite <i>c</i> shorter than sclerite <i>b</i>, not bifurcated but slightly curved distally with interno-lateral concavity that extends to sub-distal tip of sclerite, with 2–5 setae in concavity (n=2); sub-basal setae not visible where sclerites overlap and group of 12 (n=2) short setae sub-basally on sclerite <i>c</i>; anterior gonopods inconspicuous, small, with several small setae on interno-lateral face of each gonopod. Dimensions (mm): holotype male (paratype male, WAM T80671): length ca. 27, width ca. 1.7, L/W=15.9; sclerite <i>a</i> 1.072 / 0.477 (1.088 / 0.573), setae 28 (31); sclerite <i>b</i> 0.418 (0.414), basal process of sclerite <i>b</i> 0.016 (0.026), setae 9 (14); sclerite <i>c</i> 0.720 (0.800), setae 5 (2). <i>Female</i>. Similar to male, other than sexual characters, and slightly larger. <b>Distribution and habitat:</b> <i>Atelomastix sarahae</i> is only known from rocky outcrops near the summit of Mount Arid in the Cape Arid National Park (Fig. 9).
