description: <i>Atelomastix tumula</i>, sp. nov. Figs. 6, 74, 135, 136. <b>Type material:</b> AUSTRALIA: Western Australia: holotype male, Bluff Knoll walking trail, Stirling Range National Park, 34°23’S, 118°15’E, hand collected, 6 April 2004, M.S. Harvey, J.M. Waldock, K.L. Edward, C. Poustie (WAM T 74317). Paratypes: 1 male, collected with holotype (WAM T 74318). <b>Other material examined:</b> AUSTRALIA: Western Australia: 7 females, collected with holotype (WAM T 70204). <b>Etymology:</b> The specific name is an adjective based on the type locality, Bluff Knoll (<i>tumulus</i>, Latin, raised mound of earth). <b>Diagnosis:</b> <i>Atelomastix tumula</i> is generally greenish brown or dark brown with pale bands, and is relatively large in size (body width 2.4 mm, length&gt; 44 mm). This species is similar to <i>A. danksi</i>, <i>A. montana</i>, and <i>A. poustiei</i> as the anterior gonopod sclerite <i>a</i> is broad and concave sub-medially. However, it can be distinguished by the presence of two bifurcations of sclerite <i>c</i> of the male gonopod. This species exhibits a shallow asymmetrical distal bifurcation with a larger medial process and a deep asymmetrical medial bifurcation with a larger lateral process. The distal hood of sclerite <i>a</i> is not as broad as similar species, but is rather deep with the elongate pseudoflagellum entirely exposed. <b>Description:</b> <i>Male (holotype).</i> Colour: live specimens dark blue-grey with lighter bands between segments; head, antennae, ozopores and legs golden-brown, rest dark brown, prozonites green-brown, metazonites darker brown to pale white in preserved specimens. Body: ca. 44 mm long and ca. 2.4 mm wide at collum. With 60 trunk segments, 109 pairs of legs, last 2 segments without legs. Head: with ca. 21 ocelli (Fig. 74), arranged in 3 rows (6: 7: 8). Gonopods: anterior gonopods (Figs. 135, 136) very large, heavily sclerotised and complex in structure, 2.14 times longer than broad; sclerite <i>a</i> with swollen base that forms broad, concave area where pseudoflagellum emerges, and, curved distal hood that is characteristically domed; sub-distal edge of concave area of sclerite <i>a</i> with 6 larger setae; upper distal face of sclerite <i>a</i> with 22 short blunt setae; pseudoflagellum long, elongate and distally visible beneath broadened distal hood; sclerite <i>b</i> elongate and curved, terminating in a blunt, rounded tip, with 0–1 sub-distal setae; basal process of sclerite <i>b</i> large, triangular, tapering to form rounded tip, 0.39 times the length of the main process; sclerite <i>c</i> same height as sclerite <i>b</i>, almost bifurcate with medial section noticeably broad, slightly tapering to blunt concave tip, with 10 setae (n=2) on internal concave face; with group of 6–8 (n=2) fine setae on sub-basal edge of sclerite <i>b</i> instead of single sub-basal setae where sclerites overlap, and group of 10 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 T74317): length ca. 44, width ca. 2.4, L/W=18.4; sclerite <i>a</i> 1.248 / 0.584 (1.152 / 0.558), setae 8 + 6 (8 + 6); sclerite <i>b</i> 0.520 (0.499), basal process of sclerite <i>b</i> 0.204 (0.202), setae 0 (1); sclerite <i>c</i> 0.904 (0.880), setae 3 (8). <i>Female</i>. Unknown. <b>Distribution and habitat:</b> <i>Atelomastix tumula</i> is known only from two males and seven females hand collected under rocks along the Bluff Knoll walking trail in the Stirling Range National Park (Fig. 6). The habitat consists of moist jarrah (<i>Eucalyptus marginata</i>) and marri (<i>Corymbia calophylla</i>) forest with a relatively thick understorey.
