Diagnosis. Gonopod: Antichiropus patriciae Car, n. sp. is unmistakeable: it has two long solenomere processes halfway along the length of the solenomere and a second femoral process with a distinct anvil-shaped structure at its base.
Description. Male holotype: Body ca. 20 mm long; midbody ring ca. 2 mm wide, with distinct, smooth waist, metazonite slightly wider than prozonite.
Colour (in alcohol) dark brown, cream ventrally (Fig 26A): leg colour, paler. No paranota (Fig 26B).
Sternites without obvious processes/tubercles, sternal lamella short, square, broad. Leg coxal processes absent. Anterior spiracles at midbody, small, ovoid, slightly folded.
Head smooth without noticeable sculpturing; frons smooth, setose; face narrow, cardines visible when viewed face-on, maximum width ca. 4x the distance between antennal sockets; sockets separated by ca. 2x width of sock- et.
Antennae relatively slender, of moderate length, reaching to ring 2, antennal segments of similar length and width.
Collum 1x long as head (in lateral view) (Fig 26A).
Gonopod short, reaching ring 6; coxa (C)much more robust, shorter, than femorite, with very slight ridge on anterior surface; prefemur (PF) much shorter than femorite, with few setae, prefemoral lip low but pronounced; femorite (F) short, squat, curved, broader at apex; main femoral process (MFP), long with pointed tip reaching solenomere. Distinctive anvil-shaped structure at base; second femoral process (fp1) at least 1/2 femorite length, robust, pointed, curves upwards towards solenomere; prolongation of femorite (prof) absent; solenomere (S) relatively long, forming a loop/circle, narrower than femorite, of similar width along its length but broadest mid-length, narrowing to slender squared-off tip; solenomere process (sp1) not at tip, paired with second solenomere process (sp2) halfway along length of solenomere; both processes long, pointed (Figs 26 C–F).
Female: Similar to the male but slightly broader legs (WAM T76057).
Distribution. This species has been collected from several sites in the northern Pilbara (Fig 25).
Etymology. This species is named for the senior author’s younger daughter, Patricia Mellows.
