Adult female ( Figure 41a – e View FIGURE )

Dorsal shield ( Figure 41a View FIGURE ) — Dorsal shield smooth, except for the lateral area of the podosoma lightly reticulated: length 359 (344 – 373); width 175 (166 – 183) (at level of s4) and 190 (183 – 197) (at level of Z1). Seven pairs of solenostomes: gd1, gd2, gd4, gd5, gd6, gd8, and gd9. No poroid visible. Sublateral setae (r3 and R1) on the lateral margin. Dorsal shield bearing 19 pairs of setae, all smooth, except Z5 slightly serrated: j1 24 (34 – 24); j3 31 (31 – 32); j4 17 (15 – 18); j5 16 (15 – 17); j6 17 (16 – 18); J2 21 (20 – 22); J5 11 (10 – 12); z2 18 (16 – 19); z3 33 (30 – 35); z4 30 (29 – 30); z5 18 (17 – 18); Z1 20 (18 – 21); Z4 52 (50 – 53); Z5 74 (72 – 75); s4 38 (37 – 39); s6 43 (40 – 45); S2 46 (44 – 48); S4 25 (23 – 26); S5 25 (23 – 26); sub-lateral setae r3 28 (27 – 28) and R1 20 (19 – 21). Peritreme extending anteriorly to the level between j1-j3 .

Ventral shields ( Figure 41b View FIGURE ) — Sternal shield 73 (66 – 80) long and 77 (75 – 79) 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) on separate platelets accompanied by a pair of small poroids. Genital shield 128 (124 – 131) long and 63 (61 – 65) wide (at level of ST5), smooth. Four elongate platelets or genital sigilla separating genital and ventrianal shields not discernible in the specimen examined. One pair of poroids close to the genital shield (ST 5) and 1 pair of poroids around the genital shield. Ventrianal shield 124 (121 – 126) long and 98 (94 – 101) wide (at level of ZV2), smooth to faintly striate, 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 49 (47 – 51) long, smooth. Primary metapodal plate or inguinal sigillum 29 (28 – 30) long and 5 wide. In a paratype specimen: secondary metapodal plate or inguinal sigillum 21 long and 3 wide.

Spermatheca ( Figure 41c View FIGURE ) — Cervix 4 long, Ushaped.

Chelicera ( Figure 41d View FIGURE ) — Six teeth and a pilus dentilis observed on the fixed digit. Movable digit 29 (27 – 31) long, bidentate.

Legs ( Figure 41e View FIGURE ) — Measurements of legs: leg I 369 (364 – 374); leg II 339 (328 – 350); leg III 298 (294 – 302); leg IV 434 (422 – 443). Eight setae (2-2/1, 2/0-1) on the genu II. One pointed macroseta 48 (42 – 54) long, on the basitarsus IV.

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

Adult male

Described by Schicha (1987) and Denmark and Rather (1996). We were not able to borrow the male type specimens of this species.

Previous reports — N. steveni is only known from New South Wales ( Australia), on Banksia sp. ( Proteaceae ).
