Adult female ( Figure 35a – e )

Dorsal shield ( Figure 35a ) — Dorsal shield smooth, except for the lateral area of the podosoma lightly reticulated: length 418 (417 – 418); width 258 (257 – 259) (at level of s4), 269 (at level of Z1), and 280 (279 – 280) (at the level of S2). Five pairs of solenostomes on the dorsal shield: 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, except Z4 and Z5 slightly serrated: j1 38 (37 – 39); j3 56; j4 31 (30 – 31); j5 23 (22 – 23); j6 30 (29 – 30); J2 37 (35 – 39); J5 11 (10 – 11); z2 28; z3 50 (45 – 55); z4 38 (37 – 39); z5 11; Z1 46; Z4 87 (86 – 88); Z5 112 (110 – 113); s4 57 (55 – 58); s6 54 (51 – 56); S2 58 (57 – 59); S4 33 (32 – 34); S5 35 (33 – 36); sub-lateral setae r3 40 (38 – 42) and R1 31. Presence of few visible muscles marks (sigilles) on the dorsal shield. Peritreme extending anteriorly to the level of j1.

Ventral shields ( Figure 35b ) — Sternal shield 92 long and 94 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 121 (119 – 123) long and 76 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 4 pairs of poroids around the genital shield. Ventrianal shield 152 (150 – 153) long and 123 (121 – 124) wide (at level of ZV2), smooth, with three pairs of preanal setae (JV1, JV2 and ZV2; JV3 absent) and a pair of small circular solenostomes gv3 posterior or posterolateral to JV2. Three pairs of caudoventral setae (ZV1, ZV3 and JV5, JV4 absent) on the integument surrounding the ventrianal shield. Absence of the caudoventral seta JV4 allows to easily distinguish this species from all the. JV5 53 (51 – 55) long, smooth. Primary metapodal plate or inguinal sigillum 35 (34 – 35) long and 11 (10 – 11) wide.

Spermatheca ( Figure 35c ) — Cervix 10 (9 – 10) long, U-shaped.

Chelicera ( Figure 35d ) —1 Nine teeth and a pilus dentilis on the fixed digit. Movable digit 38 (36 – 39) long, bearing three teeth.

Legs ( Figure 35e ) — Measurements of legs: leg I 391 (387 – 395); leg II 334 (324 – 343); leg III 340 (331 – 348); leg IV 439. Seven setae (2-2/0, 2/0-1) on the genu II. Two macrosetae 34 (34 – 35) and 33 (32 – 33) long on the genu and tibia III, respectively. Three other knobbed macrosetae, 53 (52 – 54), 52 (50 – 54) and 54 (51 – 57) long, on the genu, tibia and basitarsus IV, respectively.

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

Adult male

Described by Collyer (1982) and Denmark and Rather (1996). We were not able to borrow male type specimens of this species.

Previous reports — N. oleariae is only known from New Zealand. The female holotype and two paratype specimens (1 female and 1 male) of N. oleariae were collected on Olearia colensoi Moench. (Asteraceae) at Ruahine Range. Other paratype specimens (2 females and 1 male) were also collected on O. colensoi at Magister Ridge (Westland), Strachan Ridge (South Westland), and Pillans Pass (Manapouri). Other specimens (excluded from the type series) were collected from both North and South islands of New Zealand. Plants on which this species was collected are: Carmichaelia sp. ( Fagaceae ); Carpodetus serratus J.R. and G.Forst. (Carpodetaceae); Coprosma polymorpha W.R.B. Oliver (Rubiaceae) ; Dacrophyllum sp. ( Podocarpaceae ); Olearia lacunosa Moench. (Asteraceae) ; Pseudowintera axillaris J.R. and G.Forst. ( Winteraceae ); Vitex lucens Kirk (Verbenaceae) .
