description: <i>Atelomastix anancita</i>, sp. nov. Figs. 8, 49, 77, 78. <b>Type material:</b> AUSTRALIA: Western Australia: holotype male, Mount Diamond, Cape Arid National Park, south side near summit, 33°38’17”S, 123°29’49”E, hand collected under rocks, 5 June 2007, M.L. Moir, M.C. Leng (WAM T 83177). Paratypes: 1 male, collected with holotype (WAM T 83178); 23 males, 6 females, collected with holotype (WAM T 80681); 6 males, 18 females, collected with holotype (WAM T 80682); 1 female, collected with holotype (WAM T 80683); 2 males, 2 males, Mount Arid, Cape Arid National Park, south side near summit, 33°57’45”S, 123°13’01”E, hand collected under granite rocks, 5 June 2007, M.L. Moir, M.C. Leng (WAM T 80673). <b>Etymology:</b> The species epithet is an adjective based on the type locality, Mount Diamond (<i>anancitus,</i> Latin, a name for the diamond when used as a remedy for distress of the mind). <b>Diagnosis:</b> The male gonopod morphology of <i>Atelomastix anancita</i> is similar to that of <i>A. melindae</i> and <i>A. flavognatha,</i> as it has a distally bifurcated sclerite <i>c</i> and the tip of sclerite <i>b</i> extends between the bifurcation and beyond the edge of sclerite <i>c</i>. It can be distinguished from these species as the medial process of the sclerite <i>c</i> bifurcation is noticeably much longer than the lateral process. The distal end of sclerite <i>b</i> is elongate, not distinctly curved, and tapers gently to a rounded tip. Setae are situated only on the subdistal curved edge of sclerite <i>b</i> and do not extend towards the distal tip as in <i>A. melindae</i>. <b>Description:</b> <i>Male (holotype).</i> Colour: generally mottled blue-grey, legs, mouthparts, gonopods golden brown; prozonites dark brown to pale brown, metazonites blue-grey in preserved specimens. Body: ca. 34 mm long and ca. 2.3 mm wide at collum. With 56 trunk segments, 101 pairs of legs, last 2 segments without legs. Head: with ca. 55 ocelli (Fig. 49), arranged in 7 rows (4: 8: 10: 10: 9: 8: 6). Gonopods: anterior gonopods (Figs. 77–78) of medium to heavy sclerotisation, 2.2 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 12–28 (n=2) short blunt setae; pseudoflagellum relatively short, fat and mostly visible beneath distal hood; sclerite <i>b</i> relatively narrow, tip extending between bifurcation and beyond edge of sclerite, tapering to blunt tip distally, with 7–11 sub-distal setae; basal process of sclerite <i>b</i> small, 0.06 times length of main process; sclerite <i>c</i> similar height as sclerite <i>b</i>, shallowly bifurcate, medial process longer, with 5–7 setae (n=2) below bifurcation; sub-basal setae absent where sclerites overlap and group of 7–8 (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 T83178): length ca. 34, width ca. 2.3, L/W=12.7; sclerite <i>a</i> 1.344 / 0.621 (1.265 / 0.525), setae 28 (12); sclerite <i>b</i> 0.403 (0.422), basal process of sclerite <i>b</i> 0.026 (0.032), setae 7 (11); sclerite <i>c</i> 0.960 (0.912), lateral process 0.045 (0.067), medial process 0.115 (0.093), setae 5 (7). <i>Female</i>. Similar to male, other than sexual characters, and slightly larger. <b>Distribution and habitat:</b> <i>Atelomastix anancita</i> is only known from rocky outcrops near the summit of Mount Diamond and Mount Arid in Cape Arid National Park (Fig. 8). All specimens were collected from beneath rocks.
