description: <i>Atelomastix brennani</i>, sp. nov. Figs. 7, 52, 83, 84. <b>Type material:</b> AUSTRALIA: <i>Western Australia:</i> holotype male, Mount Le Grand, Le Grand National Park, summit, 33°59’41”S, 122°07’48”E, hand collected under granite rocks, 4 June 2007, M.L. Moir, M.C. Leng (WAM T 83222). Paratypes: Mount Le Grand, Le Grand National Park: 21 males, 24 females, collected with holotype (WAM T 80738, T 80736); 6 males, 11 females, outcrop about Rossiter Bay, 33°59’26”S, 122°15’34”E, hand collected under granite rocks, 4 June 2007, M.L. Moir, M.C. Leng (WAM T 80727, T 80801). <b>Other material examined:</b> AUSTRALIA: Western Australia: Mount Le Grand, Le Grand National Park: 9 males, 9 females, Mississippi Hill, 33°59’39”S, 122°15’16”E, hand collected under granite rocks, 4 June 2007, M.L. Moir, M.C. Leng (WAM T 80720, T 80719); 1 male, 5 females, gully east of Mississippi Hill, 33°59’06”S, 122°15’37”E, hand collected under rotting log, 4 June 2007, M.L. Moir, M.C. Leng (WAM T 80718). <b>Etymology:</b> The specific epithet is a patronym in honour of Karl Brennan who has collected other species of <i>Atelomastix</i> in southwestern Australia. <b>Diagnosis:</b> <i>Atelomastix brennani</i> can be distinguished from other species as sclerite <i>c</i> is curved, but not bifurcate, with a very shallow lateral concavity, and the distal tip is in line with the distal tip of sclerite <i>b</i>. Sclerite <i>b</i> is curved distally to a narrow point and overlaps with the tip of sclerite <i>c</i>. The broadened distal hood of sclerite <i>a</i> is curved over touching edge of sclerite <i>b</i>. <b>Description:</b> <i>Male (holotype).</i> Colour: legs lighter brown, mouthparts yellow brown, anal segments dark brown; prozonites mottled dark brown, metazonites mottled dark brown to light fawn in preserved specimens. Body: ca. 34 mm long and ca. 2.1 mm wide at Collum. With 58 trunk segments, 103 pairs of legs, last 3 segments without legs. Head: with ca. 43 ocelli (Fig. 52), arranged in 7 rows (2: 4: 7: 9: 8: 7: 6). Gonopods: anterior gonopods (Figs. 83, 84) with light to medium sclerotisation, 2.3 times longer than broad; sclerite <i>a</i> with swollen base that forms broad, curved distal hood, overlapping with distal edge of sclerite <i>b</i>; upper distal face of sclerite <i>a</i> with 17–32 (n=2) short blunt setae; pseudoflagellum entirely obscured beneath broad distal hood; sclerite <i>b</i> rounded anteriorly, curved distally and tapering to a sharp point overlapping with tip of sclerite <i>c</i>, with 15–20 (n=2) short setae in two rows along sub-distal edge; basal process of sclerite <i>b</i> short, 0.02 times length of main process; sclerite <i>c</i> shorter than sclerite <i>b</i>, slightly concave on interno-lateral surface, curved subdistally to rounded tip, with 3–7 (n=2) setae medially; sub-basal setae absent where sclerites overlap and group of 14 (n=2) 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 T80738): length ca. 34, width ca. 2.1, L/W=16.2; sclerite <i>a</i> 1.280 / 0.557 (1.26/0.557), setae 17 (32); sclerite <i>b</i> 0.470 (0.486), basal process of sclerite <i>b</i> 0.02 (0.02), setae 20 (15); sclerite <i>c</i> 0.960 (0.928), setae 7 (3). <i>Female</i>. Similar to male, other than sexual characters, and slightly larger. <b>Distribution and habitat:</b> This species is known from four localities in the Le Grand National Park, near the summit of Mount Le Grand, Rossiter Bay and Mississipi Hill (Fig. 7). Specimens were collected from the soil or under granite rocks. This species occurs with <i>A. grandis</i> near the summit of Mount Le Grand, and <i>A. brennani</i> is noticeably smaller than <i>A. grandis</i>.
