No paranota ( Fig 22B).  Sterniteswithout obvious processes/tubercles, sternal lamella narrow, rounded. Leg coxal processes absent. Anterior spiracles at midbody, tiny, ovoid, flat.  Headsmooth 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.  Antennaerelatively long, reaching to ring 3, antennal segments of similar length and width, lightly clavate.  Collumca. 0.6x length of head (in lateral view) (Fig 22A).  Gonopodof 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. 2412564083 2004-05 RHNW Australia -22.535833 Mt Marsh 15 118.99758 38 39 RHNW02 1 Western Australia holotype 2412564074 CALM Australia 38 39 1 Western Australia holotype 2412564080 [243,830,1634,1661] WAM Australia 38 39 T144605 1 Western Australia holotype 2412564077 2004-05 WAM Australia -22.535833 Mt Marsh 15 118.99758 38 39 T146717 13 10 3 Western Australia paratype
