Adult female ( Figure 38a – d )

Dorsal shield ( Figure 38a ) — Dorsal shield distinctly reticulated along the lateral area: length 412; width 209 (at level of s4) and 218 (at level of Z1). Six pairs of solenostomes on the dorsal shield: gd1, gd2, gd4, gd5, gd6, and gd9. One pair of poroids. Sub-lateral setae (r3 and R1) on the lateral margin. Dorsal shield bearing 19 pairs of setae, all smooth, except Z5 slightly serrated: j1 25; j3 26; j4 11; j5 11; j6 15; J2 16; J5 12; z2 10; z3 16; z4 17; z5 11; Z1 15; Z4 31; Z5 48; s4 23; s6 23; S2 20; S4 17; S5 17; sublateral setae r3 20 and R1 16. Peritreme extending anteriorly to the level between j1-j3.

Ventral shields ( Figure 38b ) — Sternal shield 84 long and 91 wide (at level of ST2), smooth, with three pairs of setae (ST1, ST2 and ST3) and two pairs of poroids. Metasternal setae (ST4) inserted on separate platelets with a pair of small poroids. Genital shield 126 long and 72 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 subtriangular-shaped, 140 long and 118 wide (at level of ZV2), is smooth, with four pairs of preanal setae (JV1, JV2, JV3 and ZV2) and a pair of small and circular solenostomes gv3 posteromediad to JV3. Four pairs of caudoventral setae (ZV1, ZV3, JV4 and JV5) on the integument surrounding the ventrianal shield. JV5 44 long, smooth. Primary metapodal plate or inguinal sigillum 35 long and 8 wide.

Spermatheca ( Figure 38c ) — Cervix 8 long, cupshaped.

Chelicera ( Figure 38d ) — Five teeth and a pilus dentilis on the fixed digit. Movable digit 33 long, bidentate.

Legs ( Figure 38e ) — Measurements of legs: leg I 368; leg II 322; leg III 320; leg IV 412. Eight setae (2- 2/1, 2/0-1) on the genu II. Three knobbed macrosetae, 30, 28 and 54 long, on the genu, tibia and basitarsus IV, respectively.

Material examined — The female holotype 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 the male type specimen of this species.

Previous reports — N. spaini is only known from New Zealand ( Collyer 1982; Schicha 1987). The female holotype, paratypes and other specimens of this species are reported on Olearia colensoi (Asteraceae) at Ruahine Range and Urewera National Park.
