( Figs 22 A–F, 25) ZooBank LSID: urn:lsid:zoobank.org:act: 28AA5641-5ECF-4D7E-9319-30DC9A3C4809 Type material examined. Australia : Western Australia : holotype male (badly damaged, tail segments missing), 24 km WSW. of Mt Marsh , site RHNW02 , 22°32’09”S , 118°59’51.3”E , May 2004 , ethylene glycol pitfall traps , CALM staff (Pilbara Biological Survey) ( WAM T144605 ) . Paratypes : 1 males , collected with holotype ( WAM T76054); 2 males , 10 females (damaged remains), collected with holotype ( WAM T146717 ) . Diagnosis. Gonopod: Antichiropus lucyae Car , n. sp. is recognisable by its distinctive urn-shaped gonopodal femorite (posterior and anterior views) together with its, curved main femoral process in close association with a second femoral process. Description. Male holotype : Body ca. 10 mm long, slightly dimpled; midbody ring ca. 1.5 mm wide, with indistinct, smooth waist, prozonite and metazonite of similar width. Colour chestnut brown, lighter ventrally: rugose dorsally and laterally ( Fig 22A ): leg colour, similar to body. No paranota ( Fig 22B ). Sternites without obvious processes/tubercles, sternal lamella narrow, rounded. Leg coxal processes absent. Anterior spiracles at midbody, tiny, ovoid, flat. Head smooth without noticeable sculpturing, slight stippling; frons moderately setose; face moderately nar- row, cardines visible when viewed face-on, maximum width ca. 4x the distance between antennal sockets; sockets separated by ca. 2x width of socket. Antennae relatively long, reaching to ring 3, antennal segments of similar length and width, lightly clavate. Collum ca. 0.6x length of head (in lateral view) (Fig 22A). Gonopod of medium length, reaching ring 5; coxa (C) more robust than femorite, 1/2 femorite length with pronounced ridge on anterior surface; prefemur (PF) similar length to coxa, moderately setose, prefemoral lip pronounced; femorite (F) 2/3 acropodite length, upright, slender for proximal half, then thickening noticeably to a bulbous hourglass shape when viewed anteriorly; main femoral process (MFP) curved claw-shape, pointing towards femorite base second femoral process (fp1) slender, pointed, prolongation of femorite (prof) 1/4 length femorite, triangular, pointed, in very close association with fp1; solenomere (S) relatively short, curled in a C-shape, slender, narrowing to flattened asymmetrical point; solenomere process (sp1) at solenomere tip, upright pointed (Figs 22C- F.). Female: Similar to the male but slightly broader and stouter (body width ca. 1.75 mm when viewed dorsally), less rugose with shorter, more slender legs (WAM T76054). Distribution. All specimens of this species have been found in only one location in the Pilbara, WSW. of Mt Bruce (Fig 25). Etymology. This species is named for Lucy Hogan, daughter of the senior author.
