Adult female ( Figure 32a – e )

Dorsal shield ( Figure 32a ) — Dorsal shield smooth, except for the lateral area slightly reticulated: length 462 (456 – 467); width 266 (242 – 269) (at level of s4) and 259 (258 – 260) (at level of Z1). Five pairs of solenostomes on the dorsal shield: gd1, gd2, gd4, gd6, and gd9. No poroid visible. Sublateral setae (r3 and R1) on the lateral margin. The dorsal shield bearing 19 pairs of setae, all smooth, except Z5 slightly serrated. On the specimen examined, one seta of the J1 pair is present; this pair of setae is absent in the other type specimens examined of this species: j1 36 (35 – 37); j3 52 (47 – 56); j4 13 (12 – 13); j5 11 (10 – 12); j6 14 (12 – 16); J1 16; J2 18; J5 14; z2 17 (16 – 18); z3 32 (27 – 37); z4 29 (26 – 32); z5 11 (10 – 11); Z1 18 (17 – 18); Z4 46 (45 – 47); Z5 112; s4 34 (33 – 34); s6 24 (23 – 24); S2 23 (21 – 24); S4 19 (17 – 20); S5 17 (16 – 18); sub-lateral setae r3 21 (21 – 22) and R1 18 (17 – 19). Peritreme extending anteriorly to the level of j1.

Ventral shields ( Figure 32b ) — Sternal shield 87 (86 – 88) long and 97 (95 – 98) 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 151 (149 – 153) long and 86 (85 – 86) wide (at level of ST5), smooth. Four elongate platelets or genital sigilla separating the genital and ventrianal shields not discernible on the specimen examined. One pair of poroids close to the genital shield (ST 5) and 4 pairs of poroids around the genital shield. Ventrianal shield 153 (150 – 155) long and 117 (110 – 124) wide (at level of ZV2), smooth, with four pairs of preanal setae (JV1, JV2, JV3 and ZV2) and a pair of small circular solenostomes gv3 posterior to JV2. Four pairs of caudoventral setae (ZV1, ZV3, JV4 and JV5) on the integument surrounding the ventrianal shield. JV5 37 (33 – 40) long, smooth. Primary metapodal plate or inguinal sigillum 33 (32 – 33) long and 8 (7 – 8) wide.

Spermatheca ( Figure 32c ) — Cervix 10 (9 – 10) long, cup-shaped.

Chelicera ( Figure 32d ) — Eight teeth and a pilus dentilis on the fixed digit. Movable digit 38 (36 – 39) long, unidentate.

Legs ( Figure 32e ) — Measurements of legs: leg I 369 (397 – 427); leg II 389 (368 – 403); leg III 387 (378 – 396); leg IV 488 (464 – 512). Eight setae (2- 2/1, 2/0-1) on the genu II. Three macrosetae, 34, 32 and 28 long, on the genu, tibia and basitarsus III, respectively. Three other macrosetae, 74 (70 – 78), 68 (60 – 76) and 71 (65 – 77) 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

The male of this species is unknown.

Previous reports — N. myopori is only known from New Zealand. The female holotype and six female paratypes were collected on Myoporum laetum G. Forst. (Myoporaceae) at Clifton Coast, South of Napier. One additional report (1 female and a deutonymph), excluded from the type series, was from Dun Mountain (Nelson Province), on Holocarpus bidwillii (Hook. f.ex T.Kirk.) Quinn ( Podocarpaceae ) ( Collyer 1982).
