description: <i>Atelomastix flavognatha</i>, sp. nov. Figs. 7, 57, 94–97. <b>Type material:</b> AUSTRALIA: Western Australia: holotype male, Quaalup Homestead, 34°17’S, 119°26’E, collected at night, 30 May 1994, M.S. Harvey, J.M. Waldock (WAM T 73955). Paratypes: 1 male, 1 female, collected with holotype (WAM T 47937); 4 males, NE. slope of West Mount Barren, Fitzgerald River National Park, 34º 13’ S, 119º 26’ E, hand collected, 28 May 1994, M.S. Harvey, J.M. Waldock (WAM T 47912). Other material examined: AUSTRALIA: Western Australia: 1 male, 1 female, Mount Maxwell, near summit, Fitzgerald River National Park, 34°11’48”S, 119°19’14”E, hand collected under rocks, 7 June 2007, M.L. Moir, M.C. Leng (WAM T 80662); 1 female, Mount Maxwell, near summit, Fitzgerald River National Park, 34°11’48”S, 119°19’14”E, hand collected under rocks, 7 June 2007, M.L. Moir, M.C. Leng (WAM T 80663); 1 female, Gairdiner River, Fitzgerald River National Park, 34°15’22”S, 119°25’02”E, hand collected under rocks, 6 June 2007, M.L. Moir, M.C. Leng (WAM T 80664). <b>Etymology:</b> This species is named for its yellow mouth region (flavus, Latin, yellow; gnathos, Greek, jaw). <b>Diagnosis:</b> This species is characterised by distinctive bright yellow mouthparts and legs. Sclerite b of the male gonopods is elongate, curved downwards, with a pointed distal tip, extending past the edge of sclerite c. Sclerite c is distally bifurcate with lateral and medial processes of similar lengths. <b>Description:</b> <i>Male (holotype)</i>. Colour: legs and mouthparts bright yellow; collum, head, anal segment, ozopores, and antennae dark brown; prozonites pale golden-brown, metazonites pale blue-grey in preserved specimens. Body: ca. 27 mm long and ca. 1.8 mm wide at collum. With 50 trunk segments, 89 pairs of legs, last 2 segments without legs. Head: with ca. 43 ocelli (Fig. 57), arranged in 6 rows (4: 5: 7: 8: 9: 10). Gonopods: anterior gonopods (Figs. 94–97) lightly sclerotised, 2.65 times longer than broad; sclerite <i>a</i> with swollen base and broad, curved distal hood; upper distal face of sclerite <i>a</i> with 15–20 (n=2) short blunt setae; pseudoflagellum elongate and visible beneath broadened distal hood; sclerite <i>b</i> relatively long and curved, terminating in an elongate rounded hook, with 11–14 (n=2) distally serrate extending to sub-distal end of sclerite; basal process of sclerite <i>b</i> broad with blunt tip, 0.30 times length of main process; sclerite <i>c</i> same height as sclerite <i>b</i>, shallowly bifurcate, lateral and medial processes of similar length and relatively widely separated, with 3–4 setae (n=6) on internal face; 1 sub-basal setae where sclerites overlap and group of 11–12 (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 T47937): length ca. 27 (22), width ca. 1.8 (1.6), L/W=15 (14); sclerite <i>a</i> 1.258 / 0.474 (1.197 / 0.464), setae 20 (15); sclerite <i>b</i> 0.474 (0.474), basal process of sclerite <i>b</i> 0.022 (0.042), setae 14 (11); sclerite <i>c</i> 0.864 (0.885), lateral process of sclerite <i>c</i> 0.064 (0.109), medial process of sclerite <i>c</i> 0.058 (0.032), setae 3 (4). <i>Female</i>. Similar to male, other than sexual characters, and slightly larger. <b>Distribution and habitat:</b> This species can be found at a number of sites in the Fitzgerald River National Park (Fig. 7), where they were mostly found under rocks in mallee heath or <i>Melaleuca, Eucalypt</i> woodlands.
