Adult female ( Figure 20a – e )

Dorsal shield ( Figure 20a ) — Dorsal shield slightly reticulated throughout: length 473; width 235 (at level of s4) and 260 (at level of Z1). Six pairs of solenostomes on the dorsal shield: gd1, gd2, gd4, gd5, gd6 and gd9. No poroid visible. Sub-lateral setae (r3 and R1) on the lateral margin. Dorsal shield bearing 19 pairs of setae all smooth: j1 20; j3 20; j4 11; j5 11; j6 12; J2 broken in the specimen examined ( Denmark and Rather [1984, 1996] mentioned J2 11); J5 11; z2 11; z3 15; z4 14; z5 9; Z1 14; Z4 broken on the specimen examined ( Denmark and Rather [1984, 1996] mentioned Z4 27); Z5 39; s4 20; s6 21; S2 19; S4 14; S5 14; sub-lateral setae r3 19 and R1 18. Peritreme extending anteriorly to the level between j1-j3.

Ventral shields ( Figure 20b ) — Sternal shield 71 long and 76 wide (at level of ST2), smooth with two pairs of setae (ST1 and ST2) and two pairs of poroids. ST3 and ST4 on separate platelets and a pair of small poroids accompanying ST4. Genital shield 167 long and 87 wide (at level of ST5), smooth. Four elongate platelets or genital sigilla between genital shield and ventrianal shields. One pair of poroids close to the genital shield (ST 5) and 2 pairs of poroids around the genital shield. Ventrianal shield subtriangular-shaped, 157 long and 131 wide (at level of ZV2), smooth, with four pairs of preanal setae (JV1, JV2, JV3 and ZV2) and without solenostome gv3. Four pairs of caudoventral setae (ZV1, ZV3, JV4 and JV5) on the integument surrounding the ventrianal shield. JV5 36 long, smooth. Primary metapodal plate or inguinal sigillum 34 long and 7 wide.

Spermatheca ( Figure 20c ) — Cervix 8 long, cupshaped.

Chelicera ( Figure 20d ) — Two teeth and a pilus dentilis on the fixed digit. Movable digit 37 long, unidentate.

Legs ( Figure 20e ) — Measurements of legs: leg I 391; leg II 323; leg III 337; leg IV 417. Eight setae (2-2/1, 2/0-1) on the genu II. Three macrosetae, 25, 30 and 32 long, on genu, tibia and basitarsus IV, respectively.

Material examined — The female holotype deposited in the New Zealand Arthropod Collection ( NZAC), Landcare Research, Auckland, New Zealand.
