Adult female ( Figure 22 a – e )

Dorsal shield ( Figure 22a ) — Dorsal shield smooth: length 409; width 247 (at level of s4), 240 (at level of Z1) and 272 (at level of S2). Four pairs of solenostomes on the dorsal shield: gd2, gd4, gd6 and gd9. No poroid visible. Sub-lateral setae (r3 and R1) on the lateral margin. Dorsal shield bearing 19 pairs of setae, all except j1 on tubercles. All dorsal and sub-lateral setae smooth, except Z4 and Z5 distinctly serrated: j1 29; j3 40; j4 28; j5 26; j6 30; J2 35; J5 12; z2 25; z3 37; z4 37; z5 24; Z1 37; Z4 66; Z5 117; s4 42; s6 40; S2 48; S4 36; S5 29; sub-lateral setae r3 23 and R1 22. Peritreme extending anteriorly to the level of j1.

Ventral shields ( Figure 22b ) — Sternal shield 80 long and 92 wide (at level of ST2), smooth with three pairs of setae (ST1, ST2 and ST3) and two pairs of poroids. A pair of metasternal setae (ST4) inserted on separate platelets accompanied by a pair of small poroids. Genital shield 126 long and 83 wide (at level of ST5), smooth. Four elongate platelets or genital sigilla separating genital and ventrianal shields folded under the genital shield. One pair of poroids close to the genital shield (ST 5) and 3 pairs of poroids around the genital shield. Ventrianal shield 148 long and 120 wide (at level of ZV2), smooth, with three pairs of preanal setae (JV1, JV2 and ZV2; JV3 absent), with a pair of circular solenostomes gv3. Four pairs of caudoventral setae (ZV1, ZV3, JV4 and JV5) on the integument surrounding the ventrianal shield. JV5 53 long, smooth. Primary metapodal plate or inguinal sigillum 29 long and 8 wide.

Spermatheca ( Figure 22c ) — Cervix 6 long, Ushaped.

Chelicera ( Figure 22d ) — Nine teeth, without pilus dentilis, on the fixed digit. Movable digit 33 long, bearing three teeth.

Legs ( Figure 22e ) — Measurements of legs: leg I 443; leg II 351; leg III 361; leg IV 456. Seven setae (2-2/0, 2/0-1) on the genu II. One macroseta (32 long) on the genu III. Three other macrosetae, 47, 55 and 52 long, on genu, tibia and basitarsus IV, respectively.

Material examined — The female holotype deposited in NSW Department of Primary Industries , Agricultural Scientific Collections Unit (Acarology), Orange Agricultural Institute, Australia .
