Adult female ( Figure 10a – e )

Dorsal shield ( Figure 10a ) — Dorsal shield heavily reticulated: length 327 (320 – 334); width 187 (185 – 189) (at level of s4) and 171 (169 – 173) (at level of Z1). Three pairs of solenostomes: gd2, gd8, 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; Z5 knobbed: j1 18 (17 – 19); j3 25 (24 – 26); j4 16 (15 – 17); j5 17 (16 – 17); j6 20 (18 – 22); J2 24 (23 – 25); J5 10 (9 – 10); z2 19 (18 – 20); z3 25 (24 – 26); z4 24 (22 – 26); z5 18 (17 – 19); Z1 22 (21 – 23); Z4 31 (29 – 33); Z5 46 (42 – 50); s4 27 (25 – 29); s6 27 (26 – 28); S2 31 (30 – 31); S4 30 (29 – 30); S5 23 (22 – 23); sub-lateral setae r3 25 (24 – 26) and R1 22 (21 – 22). Peritreme extending anteriorly to the level of j1 .

Ventral shields ( Figure 10b ) — Sternal shield 71 (67 – 75) long and 69 (67 – 71) 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 110 (108 – 111) long and 67 wide (at level of ST5), is 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 3 pairs of poroids around the genital shield. Ventrianal shield much longer than wide, with distinct waist, 103 (96 – 108) long and 68 (66 – 70) 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 posteromediad to JV2. Four pairs of caudoventral setae (ZV1, ZV3, JV4 and JV5) on the integument surrounding the ventrianal shield. JV5 38 (36 – 40) long, smooth. Primary metapodal plate or inguinal sigillum 24 (22 – 25) long and 4 (3 – 4) wide.

Spermatheca ( Figure 10c ) — Cervix 15 (12 – 17) long, cup-shaped.

Chelicera ( Figure 10d ) — Two large teeth, a ridge of 6 (5 – 6) small teeth, and a pilus dentilis on the fixed digit. Movable digit 23 (21 – 25) long, bidentate.

Legs ( Figure 10e ) — Measurements of legs: leg I 275 (270 – 280); leg II 246 (242 – 250); leg III 244 (240 – 248); leg IV 303 (300 – 306). Seven setae (2-2/0, 2/0-1) on the genu II. Three knobbed macrosetae, 21 (20 – 21), 18 (17 – 18) and 33 (30 – 36) long, on genu, tibia and basitarsus IV, respectively.

Material examined — The female holotype and two female paratypes deposited in the collection of the Zoological Survey of India (ZSI) , Kolkata, India.

Adult male

The male of this species is unknown.

Previous reports — N. transitans is only known from the Oriental area, from Jammu and Kashmir ( India), on Pyrus communis L. ( Rosaceae ), and Morus sp. ( Moraceae ).
