Adult female ( Figure 31a – d )

Dorsal shield ( Figure 31a ) — Dorsal shield heavily reticulate: length 383 (381 – 384); width 193 (191 – 194) (at level of s4), 196 (194 – 197) (at level of Z1), with six pairs of solenostomes: gd1, gd2, gd4, gd6, gd8, and gd9. No poroid visible. Sub-lateral setae (r3 and R1) on the lateral margin. Dorsal shield bearing 19 pairs of setae. On one of specimens examined, one seta of the J1 pair is present. All dorsal and sub-lateral setae smooth, except Z5 serrated: j1 30 (28 – 31); j3 36 (34 – 37); j4 25 (23 – 26); j5 23 (22 – 24); j6 31 (30 – 31); J1 36; J2: 37 (36 – 37); J5 13 (12 – 13); z2 24 (22 – 25); z3 32 (31 – 32); z4 34 (33 – 34); z5 23; Z1 41 (39 – 43); Z4 48 (46 – 50); Z5 58 (56 – 59); s4 38 (37 – 39); s6 43; S2 45 (43 – 46); S4 43 (41 – 45); S5 40 (38 – 41); sub-lateral setae r3 35 (33 – 36) and R1 41 (39 – 42). Presence of few visible muscles marks (sigilles) on the dorsal shield. Peritreme extending anteriorly to the level of j3 or between j1-j3 .

Ventral shields ( Figure 31b ) — Sternal shield weakly sclerotized, 74 (73 – 74) long and 80 wide (at level of ST2), smooth, with two pairs of setae (ST1 and ST2) and two pairs of poroids. ST3 and ST4 on separate platelets with a pair of small poroids accompanying ST4. Genital shield 150 long and 76 (74 – 78) 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 4 pairs of poroids around the genital shield. Ventrianal shield subtriangular-shaped, 133 (131 – 135) long and 116 (112 – 119) wide (at level of ZV2), reticulate with four pairs of preanal setae (JV1, JV2, JV3 and ZV2), and a pair of small circular solenostomes gv3 posteromediad to JV3. Four pairs of caudoventral setae (ZV1, ZV3, JV4 and JV5) on the integument surrounding the ventrianal shield. JV5 52 (51 – 53) long, is smooth. Primary metapodal plate or inguinal sigillum 38 (35 – 40) long and 5 (4 – 6) wide.

Spermatheca — Spermatheca not discernible in the two type specimens examined. Rivnay and Swirski (1980) mentioned that the cervix has a Ushaped type.

Chelicera ( Figure 31c ) — Two or three teeth and a pilus dentilis on the fixed digit. Movable digit 39 (38 – 40) long, bears one or two teeth.

Legs ( Figure 31d ) — Measurements of legs: leg I 357 (350 – 363); leg II 302 (297 – 307); leg III 312 (302 – 321); leg IV 422 (411 – 432). Seven setae (2-2/0, 2/0-1) on the genu II. One macroseta, 38 (34 – 41) long, on the basitarsus IV.

Material examined — Two female paratypes deposited in the Division of Entomology , Agricultural Research Organization, Bet Dagan, Israel .

Adult male

The male of this species is unknown.

Previous reports — N. montforti is only known from Israel ( Swirski and Amitai 1984; Swirski and Amitai 1997a). The type specimens were collected at Monfort (Western Galilee, Israel) on Quercus calliprinos (Fagaceae) . It has since been reported on Artemisia monosperma , Limbarda crithmoides (Asteraceae) ; at Haifa (Western Carmel) on Q. calliprinos ; and on Platanus orientalis L. ( Platanaceae ).
