Type material: AUSTRALIA: Western Australia: holotype male, Mount Arid, Cape Arid National Park , south side near summit, 33°54’45”S, 123°13’01”E, hand collected under rocks, 5 June 2007, M.L. Moir, M.C. Leng ( WAM T 85863) GoogleMaps . Paratypes: Mount Arid, Cape Arid National Park : 9 males, 25 females, collected with holotype ( WAM T 80671) GoogleMaps ; 38 males, 34 females, collected with holotype ( WAM T 80674) GoogleMaps .

Etymology: The specific epithet is a patronym in honour of Sarah Comer who has collected numerous specimens of Atelomastix in southwestern Western Australia.

Diagnosis: The male gonopod morphology of Atelomastix sarahae differs from other species as sclerite c is not bifurcated but slightly curved distally with an interno-lateral concavity that extends to the sub-distal tip of the sclerite. Sclerite b is much higher than the tip of sclerite c, extends to the edge of sclerite c and curves distally to a pointed tip.

Description: Male (holotype). Colour: generally chocolate-brown with mottled blue-grey; legs, antennae, mouthparts, and gonopods golden brown; ozopores distinct and golden brown; prozonites chocolate brown, metazonites mottled blue-grey to brown in preserved specimens.

Body: ca. 27 mm long and ca. 1.7 mm wide at collum. With 56 trunk segments, 101 pairs of legs, last 2 segments without legs.

Head: with ca. 45 ocelli ( Fig. 72), arranged in 7 rows (1: 4: 7: 9: 8: 8: 8).

Gonopods: anterior gonopods ( Figs. 72, 130, 131) heavily sclerotised, 1.9–2.2 mm (n=2) times longer than broad; sclerite a with swollen base that forms broad, curved distal hood; upper distal face of sclerite a with 28–31 (n=2) short blunt setae; pseudoflagellum relatively short and partially visible beneath broad distal hood; sclerite b relatively broad, curved subdistally, tapering sharply to a pointed curved tip, with 9–14 (n=2) short setae; basal process of sclerite b short and triangular, 0.02–0.03 (n=2) times length of main process; sclerite c shorter than sclerite b, not bifurcated but slightly curved distally with interno-lateral concavity that extends to sub-distal tip of sclerite, with 2–5 setae in concavity (n=2); sub-basal setae not visible where sclerites overlap and group of 12 (n=2) short setae sub-basally on sclerite c; anterior gonopods inconspicuous, small, with several small setae on interno-lateral face of each gonopod.

Dimensions (mm): holotype male (paratype male, WAM T80671): length ca. 27, width ca. 1.7, L/W=15.9; sclerite a 1.072 / 0.477 (1.088 / 0.573), setae 28 (31); sclerite b 0.418 (0.414), basal process of sclerite b 0.016 (0.026), setae 9 (14); sclerite c 0.720 (0.800), setae 5 (2).

Female. Similar to male, other than sexual characters, and slightly larger.

Distribution and habitat: Atelomastix sarahae is only known from rocky outcrops near the summit of Mount Arid in the Cape Arid National Park ( Fig. 9 View FIGURES 7–9 ).
