description: <i>Atelomastix longbottomi</i>, sp. nov. Figs. 8, 63, 108, 109. <b>Type material:</b> AUSTRALIA: Western Australia: holotype male, southern side of Mount Belches, Duke of Orleans Bay, 33°56’36”S, 122°33’42”E, hand collected under granite rocks, 2 June 2007, M.L. Moir, A. Longbottom (WAM T 82780). Paratypes: 2 males, collected with holotype (WAM T 82781, T 82782); 3 males, 8 females, collected with holotype (WAM T 80739). <b>Etymology:</b> The specific epithet is a patronym in honour of Allan Longbottom who collected the holotype and numerous other species of <i>Atelomastix</i> in southwestern Western Australia. <b>Diagnosis:</b> <i>Atelomastix longbottomi</i> is similar to <i>A. psittacina</i> and <i>A. culleni</i> but differs in the shape of sclerites <i>a</i> and <i>b</i>. The shape of the distal hood of sclerite <i>a</i> does not curve around to touch the tip of sclerite <i>b</i> and obscure the pseudoflagellum as in <i>A. psittacina</i> and <i>A. culleni.</i> Sclerite <i>b</i> is shorter, does not extend to sclerite <i>a</i>, and does not resemble a parrot beak with only a slightly curved distal tip. Sclerite <i>c</i> is not bifurcated, but is relatively broad, straight and only slightly tapering. <b>Description:</b> <i>Male (holotype).</i> Colour: head, collum and anal segment dark brown, antennae, ozopores and legs fawn, prozonites fawn, metazonites fawn to darker brown in preserved specimens. Body: ca. 21 mm long and ca. 1.5 mm wide at collum. With 44 trunk segments, 75 pairs of legs, last 3 segments without legs. Head: with ca. 23 ocelli (Fig. 63), arranged in 5 rows (2: 4: 5: 6: 6). Gonopods: anterior gonopods (Figs. 108, 109) lightly sclerotised, 2.4 times longer than broad; sclerite <i>a</i> with swollen base that forms curved distal hood; upper distal face of sclerite <i>a</i> with 10–16 (n=2) short blunt setae; pseudoflagellum relatively short and visible beneath distal hood; sclerite <i>b</i> broad, slightly curved distally, tapering to blunt tip, distal edge weakly serrate, with 7–8 (n=2) short setae; basal process of sclerite <i>b</i> short and broad, 0.03 times length of main process; sclerite <i>c</i> slightly shorter than sclerite <i>b</i>, not bifurcate, broad basally, tapering slightly to blunt tip, with 5 medial setae; long sub-basal setae present where sclerites overlap and group of 5–8 (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 T82781): length ca. 21, width ca. 1.5, L/W=14; sclerite <i>a</i> 0.912 / 0.384 (1.00/0.454), setae 16 (10); sclerite <i>b</i> 0.294 (0.336), basal process of sclerite <i>b</i> 0.011 (0.011), setae 8 (7); sclerite <i>c</i> 0.621 (0.672), setae 5 (5). <i>Female</i>. Similar to male, other than sexual characters, and slightly larger. <b>Distribution and habitat:</b> <i>Atelomastix longbottomi</i> is only known from the southern side of Mount Belches on Duke of Orleans Bay (Fig. 8). A total of six males and eight females were found under granite rocks, in sympatry with <i>A. melindae</i>.
