Diagnosis. Gonopod: Antichiropus cunicularis Car, n. sp. is distinguishable from other similar species, namely A. spathion Car, n. sp. (Fig 37) A. sloanae Car, n. sp. (Fig 36) and A. simmonsi Car, n. sp. (Fig 35) by the size of the main femoral process and the prolongation of the femorite: in A. cunicularis both structures ca. 1/3 length of the solenomere, but are much smaller in the other species. In addition, A. cunicularis has a banana-shaped main femoral process, different from those of the other species.
Description. Male holotype: Body ca. 25–30 mm long, smooth; midbody ring ca. 2 mm wide, with moderately deep, smooth waist, metazonite slightly wider than prozonite width.
Colour (in alcohol) very dark brown (Fig 12A): leg colour, dark brown, lighter near body. Slight protuberances representing paranota (Fig 12B).
Sternites without obvious processes/tubercles, sternal lamella mushroom-shaped. Leg coxal processes absent. Anterior spiracles at midbody, tiny, circular, flat.
Head smooth without noticeable sculpturing; frons sparsely setose; face narrow, maximum width ca. 4x the distance between antennal sockets; sockets separated by ca. 1.5x width of socket.
Antennae, slender, of moderate length, reaching to ring 2, antennal segments of similar length and width;
Collum 1x head length (in lateral view) (Fig 13A).
Gonopod of medium length, reaching ring 5; coxa (C) robust, broader than femorite and 2/3 femorite length, with pronounced ridge on anterior surface; prefemur (PF) ½ length of femorite, setose, slight prefemoral lip; femo- rite (F) 1/2 acropodite length, upright, with slight widening then narrowing at femoral process; (MFP) main femoral process 1/2 length of solenomere, broad, long, upright with asymmetrical point; second femoral process (fp1) absent; prolongation of femorite (prof) curved, pointed; solenomere (S) moderately long, forming an open loop, widest at mid-length, tapering before widening again to a leaf-like tip with asymmetrical point; solenomere process (sp1) tiny on solenomere tip; second solenomere process 2 (sp2) slender, pointed, at narrowest point on solenomere behind tip (Fig 12 C–F).
Female: Very similar to male but with shorter, more slender legs (WAM T123217).
Distribution. This species is known from a single site, situated north-east of the town of Newman (Fig 17).
Etymology. This species is named for the shape of the main femoral process and prolongation of the femorite on the gonopod, which, when seen together in anterior view, resemble rabbit ears (Latin, adjective, cunicularis, of rabbits).
