Type material: AUSTRALIA: Western Australia: holotype male, Mount Diamond, Cape Arid National Park , south side near summit, 33°38’17”S, 123°29’49”E, hand collected under rocks, 5 June 2007, M.L. Moir, M.C. Leng ( WAM T 83177) GoogleMaps . Paratypes: 1 male, collected with holotype ( WAM T 83178) GoogleMaps ; 23 males, 6 females, collected with holotype ( WAM T 80681) GoogleMaps ; 6 males, 18 females, collected with holotype ( WAM T 80682) GoogleMaps ; 1 female, collected with holotype ( WAM T 80683) GoogleMaps ; 2 males, 2 males, Mount Arid, Cape Arid National Park , south side near summit, 33°57’45”S, 123°13’01”E, hand collected under granite rocks, 5 June 2007, M.L. Moir, M.C. Leng ( WAM T 80673) GoogleMaps .

Etymology: The species epithet is an adjective based on the type locality, Mount Diamond (anancitus, Latin, a name for the diamond when used as a remedy for distress of the mind).

Diagnosis: The male gonopod morphology of Atelomastix anancita is similar to that of A. melindae and A. flavognatha , as it has a distally bifurcated sclerite c and the tip of sclerite b extends between the bifurcation and beyond the edge of sclerite c. It can be distinguished from these species as the medial process of the sclerite c bifurcation is noticeably much longer than the lateral process. The distal end of sclerite b is elongate, not distinctly curved, and tapers gently to a rounded tip. Setae are situated only on the subdistal curved edge of sclerite b and do not extend towards the distal tip as in A. melindae .

Description: Male (holotype). Colour: generally mottled blue-grey, legs, mouthparts, gonopods golden brown; prozonites dark brown to pale brown, metazonites blue-grey in preserved specimens.

Body: ca. 34 mm long and ca. 2.3 mm wide at collum. With 56 trunk segments, 101 pairs of legs, last 2 segments without legs.

Head: with ca. 55 ocelli ( Fig. 49 View FIGURES 48–59 ), arranged in 7 rows (4: 8: 10: 10: 9: 8: 6).

Gonopods: anterior gonopods ( Figs. 77–78) of medium to heavy sclerotisation, 2.2 times longer than broad; sclerite a with swollen base that forms broad, curved distal hood; upper distal face of sclerite a with 12–28 (n=2) short blunt setae; pseudoflagellum relatively short, fat and mostly visible beneath distal hood; sclerite b relatively narrow, tip extending between bifurcation and beyond edge of sclerite, tapering to blunt tip distally, with 7–11 sub-distal setae; basal process of sclerite b small, 0.06 times length of main process; sclerite c similar height as sclerite b, shallowly bifurcate, medial process longer, with 5–7 setae (n=2) below bifurcation; sub-basal setae absent where sclerites overlap and group of 7–8 (n=2) short setae sub-basally on sclerite c; posterior gonopods inconspicuous, small, with several small setae on interno-lateral face of each gonopod.

Dimensions (mm): holotype male (paratype male, WAM T83178): length ca. 34, width ca. 2.3, L/W=12.7; sclerite a 1.344 / 0.621 (1.265 / 0.525), setae 28 (12); sclerite b 0.403 (0.422), basal process of sclerite b 0.026 (0.032), setae 7 (11); sclerite c 0.960 (0.912), lateral process 0.045 (0.067), medial process 0.115 (0.093), setae 5 (7).

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

Distribution and habitat: Atelomastix anancita is only known from rocky outcrops near the summit of Mount Diamond and Mount Arid in Cape Arid National Park ( Fig. 8 View FIGURES 7–9 ). All specimens were collected from beneath rocks.
