textitAdult female ( Figure 14a – e )

Dorsal shield ( Figure 14a ) — Dorsal shield lightly reticulated: length 399; width 228 (at level of s4) and 233 (at level of Z1). Five pairs of solenostomes: 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 which are slightly serrated: j1 25; j3 27; j4 18; j5 19; j6 20; J2 21; J5 12; z2 19; z3 28; z4 28; z5 18; Z1 20; Z4 38; Z5 57; s4 26; s6 27; S2 31; S4 25; S5 23; sub-lateral setae r3 21 and R1 20. Peritreme extending anteriorly to the level of j1.

Ventral shields ( Figure 14b ) — Sternal shield 86 long and 82 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 126 long and 73 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 2 pairs of poroids around the genital shield. Ventrianal shield much longer than wide, 144 long and 110 wide (at level of ZV2), smooth, with three pairs of preanal setae (JV1, JV2 and ZV2; JV3 absent), with a pair of small circular solenostomes gv3 posterior to JV2. Four pairs of caudoventral setae (ZV1, ZV3, JV4 and JV5, JV3 absent) on the integument surrounding the ventrianal shield. JV5 41 long, smooth. Primary metapodal plate or inguinal sigillum 28 long and 7 wide.

Spermatheca ( Figure 14c ) — Cervix 6 long, shallowly cup-shaped.

Chelicera ( Figure 14d ) — Nine teeth and a pilus dentilis on the fixed digit. Movable digit 35 long, bearing three teeth.

Legs ( Figure 14e ) — Measurements of legs: leg I 353; leg II 322; leg III 302; leg IV 395. Seven setae (2- 2/0, 2/0-1) on the genu II. Three pointed macrosetae, 31, 33 and 49 long, on genu, tibia and basitarsus IV, respectively.

Material examined — The female holotype deposited in the South Australian Museum , Adelaide, Australia .

Adult male

Described by Schicha (1978). We were not able to borrow the male type specimens of this species.

Previous reports — The type specimens of N. nesbitti were collected from Australia (New South Wales) on Medicago arborea L. ( Fabaceae ). This species was reported from two biogeographical areas: Australasian and Oriental areas. Countries in which N. nesbitti was recorded are: Australia (New South Wales) ( Womersley 1954; Schicha 1975; Wainstein 1977; Schicha 1978). Australia (Tasmania) ( Schicha 1987); India (Delhi) (Narayanan and Ghai 1961). Plants on which this species was collected are: Actinidia chinensis Planch. (Actinidiaceae) ; Banksia integrifolia L.f. ( Proteaceae ); Eucalyptus parivolia (Myrtaceae) ; Casuarina sp. ( Casuarinaceae ); Hydrangea macrophylla (Thunb.) Ser. (Hydrangeaceae) ; Malus domestica (Rosaceae) ; Mangifera indica L. ( Anacardiaceae ).
