Type material: AUSTRALIA: Western Australia: holotype male, south end of Millinup Pass, Porongurup Range National Park , 34°41’43”S, 117°53’51”E, hand collected under rotting logs, 30 March 1996, M.S. Harvey, J.M. Waldock, B.Y. Main ( WAM T 69805) GoogleMaps . Paratype: 1 male, collected with holotype ( WAM T 71601) GoogleMaps .

Etymology: The specific epithet is a patronym in honour of Julianne Waldock who collected the holotype and numerous other species of Atelomastix in southwestern Western Australia.

Diagnosis: Atelomastix julianneae can be distinguished from other Atelomastix species as it is characterised by a very large, broad, and distally rounded sclerite b. Sclerite c is not bifurcate, is relatively broad, subdistally narrowed and curved to a rounded tip, with 12 setae positioned on a wide section of the sclerite, partially hidden by sclerite b. This species also has 7 eye rows. Live specimens of A. julianneae have a very striking colour pattern of black or dark brown segments with bright yellow-orange bands, similar to A. tigrina .

Description: Male (holotype). Colour: live specimens dark brown-black with yellow-orange bands between segments; head, collum, anal segment dark brown, rest of body yellow-orange, prozonites light yellow-brown, metazonites dark brown to yellow in preserved specimens.

Body: ca. 36 mm long and ca. 1.8 mm wide at collum. With 56 trunk segments, 101 pairs of legs, last 2 segments without legs.

Head: with ca. 39 ocelli ( Fig. 61), arranged in 7 rows (1: 3: 5: 6: 7: 8: 9).

Gonopods: anterior gonopods ( Figs. 104, 105) very large, heavily sclerotised and complex in structure, 2.28 times longer than broad; sclerite a with swollen base and broad, curved distal hood; upper distal face of sclerite a with 18–21 (n=2) short blunt setae; pseudoflagellum short, broad, and entirely visible on externolateral side of gonopod but not visible on interno-lateral side, where it is concealed within distal hood; sclerite b broad, slightly curved inwards, with 5–7 (n=2) long setae that curve to distal end of sclerite; basal process of sclerite b long, triangular, tapering to blunt tip, 0.26 times length of main process; sclerite c not bifurcate, broad, with 12 setae (n=2) on broad internal face; with very long sub-basal setae where sclerites overlap and group of 11–15 (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 T 71601): length ca. 36 (44), width ca. 1.8 (1.8); L/W=19.6 (24.1); sclerite a 1.130 / 0.496 (1.026 / 0.461), setae 21 (18); sclerite b 0.502 (0.493), basal process of sclerite b 0.130 (0.137), setae 7 (5); sclerite c 0.899 (0.808), setae 12 (12) GoogleMaps .

Female. Unknown.

Distribution and habitat: This species has only been recorded from the Porongurup Range National Park ( Fig. 5 View FIGURES 4–6 ) and specimens were collected from under rotting eucalypt logs.
