description: <i>Atelomastix dendritica</i>, sp. nov. Figs. 8, 55, 89–91. <b>Type material:</b> AUSTRALIA: Western Australia: holotype male, Woody Island, Recherche Archipelago, 33°57’S, 121°59’E, in damp leaf litter, 8 May 1999, A.F. Longbottom (WAM T 47933). Paratype: 1 male, collected with holotype (WAM T 74296). <b>Etymology:</b> This species is named for the type locality, Woody Island (<i>dendron</i>, Greek, tree). <b>Diagnosis:</b> The male gonopod sclerite <i>b</i> shape of <i>Atelomastix dendritica</i> is similar to <i>A. flavognatha</i>, but can be distinguished by the lack of bifurcation of sclerite <i>c</i>. Sclerite <i>c</i> is curved distally, with a slight submedial concavity. Sclerite <i>b</i> is longer than sclerite <i>c</i>, and the distal tip extends beyond the edge of sclerite <i>c</i>. <b>Description:</b> <i>Male (holotype).</i> Colour: head, collum and antennae dark brown, legs and ozopores goldenbrown legs, prozonites dark blue to dark brown, metazonites light brown in preserved specimens. Body: ca. 36 mm long and ca. 2.2 mm wide at collum. With 55 trunk segments, 99 pairs of legs, last 2 segments without legs. Head: with ca. 42 ocelli (Fig. 55), arranged in 6 rows (2: 4: 8: 9: 9: 10). Gonopods: anterior gonopods (Figs. 89–91) lightly sclerotised, 2.40 times longer than broad; sclerite <i>a</i> with swollen base and curved distal hood; upper distal face of sclerite <i>a</i> with 20–21 (n=2) short blunt setae; pseudoflagellum relatively short and visible beneath distal hood; sclerite <i>b</i> relatively large and curved, terminating in an elongate rounded hook beyond top of sclerite <i>c</i>, with 11–12 (n=2) setae extending to sub-distal end of sclerite; basal process of sclerite <i>b</i> short and broad, 0.02 times length of main process; sclerite <i>c</i> shorter than sclerite <i>b</i>, not bifurcate, ending distally with blunt hook, with 6–8 setae (n=2) on internal face; sub-basal setae absent where sclerites overlap and group of 14–18 (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 T 74296): length ca. 36 (40), width ca. 2.2 (2.5), L/W=16.5 (16.6); sclerite <i>a</i> 1.552 / 0.648 (1.632 / 0.691), setae 20 (21); sclerite <i>b</i> 0.627 (0.634), basal process of sclerite <i>b</i> 0.029 (0.033), setae 11 (12); sclerite <i>c</i> 1.029 (1.056), setae 6 (8). <i>Female</i>. Unknown. <b>Distribution and habitat:</b> This species is only known from two males collected from damp leaf litter on Woody Island in the Recherche Archipelago (Fig. 8).
