description: <i>Atelomastix priona</i>, sp. nov. Figs. 8, 69, 122–124. <b>Type material:</b> AUSTRALIA: Western Australia: holotype male, Kangawarie clearing, ca. 50 km NW. of Israelite Bay, hut area, 33°13’36”S, 123°38’16”E, hand collected in leaf litter, 7 August 2004, A.F. Longbottom (WAM T 72121). Paratype: 1 female, collected with holotype (WAM T 72122). <b>Etymology:</b> This species is named for the serrate or saw-shaped distal edge of the male gonopod sclerite <i>b</i> (<i>prionos</i>, Greek, saw). <b>Diagnosis:</b> <i>Atelomastix priona</i> can be distinguished from other species by the distinctive serrated, or sawlike distal edge of sclerite <i>b</i>. In addition, sclerite <i>c</i> is not bifurcate, has a concavity on the interno-lateral side of the gonopod, is distally tapering and curved, and the distal edge is similar in height to sclerite <i>b</i>. <b>Description:</b> <i>Male (holotype).</i> Colour: head, collum, anal segment, antennae, and anal valves dark brown, legs and gonopod light brown; prozonites mottled chocolate brown, metazonites dark brown to golden brown in preserved specimen. Body: ca. 42 mm long and ca. 2.6 mm wide at collum. With 61 trunk segments, 111 pairs of legs, last 2 segments without legs. Head: with ca. 53 ocelli (Fig. 69), arranged in 6 rows (6: 7: 9: 10: 10: 11). Gonopods: anterior gonopods (Figs. 122–124) lightly sclerotised, 2.4 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 23 short blunt setae; pseudoflagellum relatively short and partially visible beneath distal hood; sclerite <i>b</i> broad, slightly curved distally, distal edge serrate like saw, with 16 short setae; basal process of sclerite <i>b</i> small short, 0.03 times length of main process; sclerite <i>c</i> same height as sclerite <i>b</i>, slightly bifurcate, lateral process long, thin, slightly curved distally, medial process very small, triangular, with 3 setae between lateral and medial processes; sub-basal setae absent where sclerites overlap and group of 20 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: length ca. 42, width ca. 2.6 (L/W=16.4); sclerite <i>a</i> 1.544/0.64, setae 23; sclerite <i>b</i> 0.497, basal process of sclerite <i>b</i> 0.045, setae 16; sclerite <i>c</i> 1.00, setae 3. <i>Female</i>. Similar to male, other than sexual characters, and slightly larger. <b>Distribution and habitat:</b> This species is only known from one male and one female collected from Kangawarie clearing, about 50 km northwest of Israelite Bay (Fig. 8).
