Adult female ( Figure 23a – e )

Dorsal shield ( Figure 23a ) — Dorsal shield smooth: length 385; width 215 (at level of s4) and 255 (at level of Z1). Six pairs of solenostomes observed: gd1, gd2, gd4, gd6, gd8 and gd9. Four pairs of poroids. Sub-lateral setae (r3 and R1) on the lateral margin. Dorsal shield bearing 19 pairs of setae, all smooth except for Z4 and Z5 which are slightly serrated: j1 29; j3 43; j4 5; j5 6; j6 9; J2 8; J5 11; z2 6; z3 48; z4 7; z5 6; Z1 6; Z4 121; Z5 232; s4 67; s6 7; S2 9; S4 10; S5 11; sub-lateral setae r3 15 and R1 12. Peritreme extending anteriorly to the level of j1.

Ventral shields ( Figure 23b ) — Sternal shield 77 long and 70 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 120 long and 68 wide (at level of ST5), smooth. Four elongate platelets or genital sigilla situated between genital and ventrianal shields. One pair of poroids close to the genital shield (ST 5) and 2 pairs of poroids around the genital shield. Ventrianal shield, longer than wide 124 long and 101 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 posterior to JV2. Four pairs of caudoventral setae (ZV1, ZV3, JV4 and JV5) inserted on the integument surrounding the ventrianal shield. JV5 93 long, smooth. Primary metapodal plate or inguinal sigillum 25 long and 7 wide.

Spermatheca ( Figure 23c ) — Cervix 11 long, Ushaped.

Chelicera ( Figure 23d ) — Eight teeth and a pilus dentilis on the fixed digit. Movable digit 30 long, bearing three teeth.

Legs ( Figure 23e ) — Measurements of legs: leg I 403; leg II 318; leg III 313; leg IV 427. Seven setae (2-2/0, 2/0-1) on the genu II. One pointed macroseta (38 long) on the genu III. Three other pointed macrosetae, 82, 65 and 77 long, on genu, tibia and basitarsus IV, respectively.

This species is easily distinguished from all other species of this genus by the lengths of Z4 (121) and Z5 (232).

Material examined — The female lectotype deposited in the BMNH, the British Museum of Natural History , Cromwell Road, London, UK .

Adult male

Described by Collyer (1964) and Schicha (1980). We were not able to borrow the male type specimens of this species.

Previous reports — The type specimens of N. cottieri were collected from New Zealand on thistle ( Asteraceae ). This species is only known from the Australasian area: Australia ( Wainstein 1977; Schicha 1980, 1987) and New Zealand ( Collyer 1964, 1982). Plants on which this species was collected are: Astelia sp. ( Asteliaceae ); Cassiniae sp. ( Asteraceae ); Fragaria x ananassa Duchesne, Malus domestica (Rosaceae) ; Hebe sp. ( Plantaginaceae ); Humulus lupulus L. ( Cannabaceae ); Trifolium repens L. ( Fabaceae ) and on moss samples.
