Dorsal shield ( Figure 26a ) — Dorsal shield heavily reticulated throughout: length 356; width 201 (at level of s4) and 226 (at level of Z1). Six pairs of solenostomes on the dorsal shield: gd1, gd4, gd5, gd6, gd8, and gd9. One pair of poroids. Sublateral setae (r3 and R1) on the lateral margin. Dorsal shield bearing 19 pairs of setae, all smooth except for Z4 (slightly serrated) and Z5 (distinctly serrated), and on tubercles: j1 18; j3 20; j4 16; j5 16; j6 18; J2 22; J5 9; z2 16; z3 20; z4 20; z5 17; Z1 21; Z4 25; Z5 42; s4 19; s6 21; S2 22; S4 23; S5 25; sub-lateral setae r3 18 and R1 18. Peritreme extending anteriorly to the level j1.

Ventral shields ( Figure 26b ) — Sternal shield 67 long and 72 wide (at level of ST2), smooth, with three pairs of setae (ST1, ST2 and ST3) and two pairs of poroids. The metasternal setae (ST4) on separate platelets accompanied by a pair of small poroids. Genital shield 128 long and 67 wide (at level of ST5), smooth. Four elongate platelets or genital sigilla separating genital and ventrianal shields folded under genital shield. One pair of poroids close to the genital shield (ST 5) and 3 pairs of poroids around the genital shield. Ventrianal shield subgquadrateshaped, 122 long and 92 wide (at level of ZV2), smooth, with three pairs of preanal setae (JV1, JV2 and ZV2; JV3 absent) and a pair of large solenostomes gv3 posteromediad to JV2. Four pairs of caudoventral setae (ZV1, ZV3, JV4 and JV5) on the integument surrounding the ventrianal shield. JV5 22 long, smooth. Primary metapodal plate or inguinal sigillum 30 long and 6 wide.

Spermatheca ( Figure 26c ) — Cervix 4 long, shallowly cup-shaped.

Chelicera ( Figure 26d ) — Seven or eight teeth and a pilus dentilis on the fixed digit. Movable digit 31 long, bearing three teeth.

Legs ( Figure 26e ) — Measurements of legs: leg I 299; leg II 270; leg III 264; leg IV 332. Seven setae (2-2/0, 2/0-1) on the genu II. Two thick and short macrosetae, 6 and 22 long, on genu and basitarsus IV, respectively.

Material examined — The female holotype deposited in NSW Department of Primary Industries, Agricultural Scientific Collections Unit (Acarology), Orange Agricultural Institute, Australia.

Adult male

The male of this species is unknown.

Previous reports — N. elaeocarpi is only known from Queensland ( Australia), on Elaeocarpus coorangooloo J. Bailey and C. White (Elaeocarpaceae) .
