Diagnosis. Gonopod: Antichiropus pendiculus Car, n. sp. is most similar to A. cirratus Car, n. sp. (Fig 7): both have long, slender, curled solenomeres, distinct from those of all other Pilbara species. Antichiropus cirratus has, however, a noticeable protuberance on the distal end of the femorite, lacking in A. pendiculus. The most noticeable feature of A. pendiculus is that it lacks a solenomere process of any description, though it does conform to the genus in its other characteristics (Car et al., 2013).
Description. Male holotype: Body ca. 12.5 mm long; midbody ring ca. 1 mm wide, with distinct, smooth waist, prozonite narrower than metazonite.
Colour (in alcohol) brown overall, pale brown ventrally (Fig 27A); leg colour as for body. No obvious paranota (Fig 27B).
Sternites without obvious processes/tubercles, sternal lamella narrow, heart-shaped. Leg coxal processes absent. Anterior spiracles at midbody small, flat.
Head smooth, with no sculpturing; frons smooth, with setae; face narrow, maximum width ca. 3x the distance between antennal sockets; sockets separated by ca. 1.5x width of socket. Antennae clavate, stocky, short, reaching only to collum, antennomere 5 wider than proximal ones.
Collum 0.8x as long as head (in lateral view) (Fig 27A).
Gonopod short, reaching ring 6; coxa (C) damaged (not shown in Fig 27); prefemur (PF) considerably shorter than femorite, setose; prefemoral lip pronounced; femorite (F) ca. 2/3 of acropodite length in situ, upright; main femoral process (MFP) slender, finger-like, pointed, curving over anterior femorite; second femoral process (fp1) large, pointed, triangular; prolongation of femorite (prof) absent; solenomere (S) very long, slender, smooth, form- ing circle that curls round at 45 o to the upright femorite; solenomere tip smooth, pointed; solenomere process (sp1) absent (Figs 27 C–F).
Female: unknown.
Distribution. To date, found only in a mining area known as Area C in the Pilbara region, west-north-west of the town of Newman (Fig 33).
Etymology. This species is named for the slender, long solenomere curled in a circle (Latin, noun, pendiculus, cord, noose).
