Type material examined. Australia: Western Australia: holotype male (damaged, possibly bleached), Warrawagine Station, near Pulgorah Cone, Pilbara Survey site NE09, 21°19’19”S, 121°00’08”E, 16 November 2003 –17 May 2004, ethylene glycol pitfall traps CALM staff (Pilbara Biological Survey) (WAM T144619). Paratypes: 1 male (damaged), Warrawagine Station, near Pulgorah Cone, Pilbara Survey site NE09, 21°19’19”S, 121°00’08”E, 16 November 2003–17 May 2004, ethylene glycol pitfall traps CALM staff (Pilbara Biological Survey) (WAM T76145); 7 males (damaged), Warrawagine Station, near Pulgorah Cone, Pilbara Survey site NE09, 21°19’19”S, 121°00’08”E, 16 November 2003–17 May 2004, ethylene glycol pitfall traps CALM staff (Pilbara Biological Sur- vey) (WAM T146715).

Other material examined. Australia: Western Australia: 2 males, 1 female, 1 juvenile, 45 km ESE. of Meen- theena Outcamp, Pilbara Biological Survey site NE06, 21°19’47.6”S, 120°52’32.4”E, May 2004, CALM staff (Pil- bara Biological Survey) (WAM T76067).

Diagnosis. Gonopod: Antichiropus julianneae Car, n. sp. is easily separated from all other Pilbara species be- cause both the prolongation of the femur and any solenomere process are lacking in this species.

Description. Male holotype: Body ca. 13 mm long; midbody ring ca. 1.5 mm wide, with slight, smooth waist, metazonite and prozonite similar widths.

Colour (in alcohol) golden brown, possibly bleached (Fig 20A): leg colour as for body. No paranota (Fig 20B).

Sternites without obvious processes/tubercles, sternal lamella slightly helmet-shaped. Leg coxal processes absent. Anterior spiracles at midbody very small, ovoid, flat.

Head smooth without noticeable sculpturing; frons smooth with some setae; face narrow, cardines visible when viewed face-on, maximum width ca. 4x the distance between antennal sockets; sockets separated by ca. 1.5x width of socket.

Antennae, relatively long, reaching to ring 3, antennomeres of similar size and shape. Collum ca. 0.75x as long as head (in lateral view) ( Fig 20A .).

Gonopod of medium length, reaching posterior edge of ring 5; coxa (C) of similar length, relatively setose, more robust than femorite, with slight ridge; prefemur (PF) 1/2 femorite length, setose, with slight lip; femorite (F) 2/3 acropodite length, upright, thickening and slightly curved towards apex; main femoral process (MFP) 1/3 length of femorite, straight, narrow, pointed; second femoral process (fp1) similar to MFP in length, narrow, pointed, slightly curved; prolongation of femorite (prof) absent; solenomere (S) of moderate length, forming a C-shape, generally thinner than femorite, of similar thickness along length but slightly thicker mid-length, narrowing considerably near tip, curving in semicircle; solenomere tip broadens to leaf shape; solenomere process (sp1) absent ( Figs 20 C–F).

Female: of similar size to the male, but stouter with more slender, shorter legs (WAM T76067).

Distribution. This species has been found only from a small area at or near Warrawagine Station ( Fig 25 ).

Etymology. The specific epithet is in honour of Julianne Waldock who has considerable expertise in the collecting and identifying of millipedes, as well as providing unfailing support and encouragement to the senior author both in the field and in the laboratory.
