FIGURE 25. Map showing the known distributions of A. hystricosus Car , n. sp. , A. julianneae Car , n. sp. , A. literulus Car , n. sp. , A. lucyae Car , n. sp. , A. patriciae Car , n. sp. and A. nicholasi Car , n. sp. 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).

Antichiropus patriciae Car , n. sp. , holotype male ( WAM T146652 ): A–B, habitus: A , lateral view; B , dorsal view; C–F, left gonopod: C , posterior view; D , anterior view; E , medial view; F , lateral view. Abbreviations : C, coxa; F, femorite; fp1, femoral process two; MFP, main femoral process; PF, prefemur; S, solenomere; sp1 and sp2, solenomere processes 1 and 2. Scale bars : A = 2 mm ; B = 1 mm ; C–F = 0.5 mm . 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.
