Adult female ( Figure 7a – d )

Dorsal shield ( Figure 7a ) — Dorsal shield heavily reticulated throughout: length 380 (370 – 390); width 197 (194 – 200) (at level of s4), 242 (238 – 246) (at level of Z1). Three pairs of solenostomes: gd2, gd6, and gd9 (gd5 is present on the specimen designated as lectotype by Kolodochka [2009] but not on the specimens presently examined or the other specimens designated as paralectotypes). Our examination of six specimens of this species collected on Acer platanoides in Massif Central ( France) also showed that gd5 is absent. Five pairs of poroids. Sub-lateral setae (r3 and R1) on the lateral margin. Dorsal shield bearing 19 pairs of setae, all dorsal and sub-lateral setae smooth: j1 19 (17 – 20); j3 25 (24 – 25); j4 12 (11 – 13); j5 14 (13 – 15); j6 20 (19 – 20); J2 25 (23 – 27); J5 13 (12 – 13); z2 15 (14 – 16); z3 25 (23 – 27); z4 27; z5 16 (15 – 16); Z1 22 (21 – 22); Z4 29 (27 – 30); Z5 44 (42 – 46); s4 27; s6 25 (23 – 27); S2 26 (25 – 26); S4 24 (23 – 24); S5 19 (17 – 20); sub-lateral setae r3 20 (19 – 20) and R1 19 (17 – 20). Peritreme extending anteriorly to the level of j3 or between j1-j3.

Ventral shields ( Figure 7b ) — Sternal shield (in poor conditions in the specimens examined) 60 (58 – 62) long and 59 (58 – 60) wide (at level of ST2), smooth with two pairs of setae (ST1 and ST2) and two pairs of small poroids. Third and fourth pairs of sternal setae (ST3, ST4) on separate platelets. A pair of small poroids accompanying ST4. Genital shield 124 (120 – 128) long and 65 (64 – 65) wide (at level of ST5), smooth. Four elongate platelets or genital sigilla between genital and ventrianal shields. One pair of poroids close to the genital shield (ST 5) and 4 pairs of poroids around the genital shield. Ventrianal shield subquadrate-shaped 114 (110 – 117) long and 98 (95 – 100) wide (at level of ZV2), lightly reticulated throughout, with four pairs of preanal setae (JV1, JV2, JV3 and ZV2), and a pair of circular solenostomes gv3 posteromediad to JV3. Four pairs of caudoventral setae (ZV1, ZV3, JV4 and JV5) on the integument surrounding the ventrianal shield. JV5 17 (15 – 18) long, smooth. Primary metapodal plate or inguinal sigillum 35 (33 – 36) long and 5 (4 – 5) wide.

Spermatheca ( Figure 7c ) — Cervix 4 (3 – 4) long, shallowly cup-shaped.

Chelicera ( Figure 7d ) — Five teeth and a pilus dentilis on the fixed digit. The movable digit 35 (33 – 36) long, bidentate.

Legs — Measurements of legs: leg I 268 (266 – 269); leg II 235 (233 – 237); leg III 233 (231 – 234); leg IV 290 (289 – 291). Seven setae (2-2/0, 2/0-1) on the genu II. No macroseta on legs.

Material examined — A female syntype, designated now as paralectotype by Kolodochka (2009), and two other female paralectotype, deposited in the ASU, Institute of Zoology , Academy of Sciences, Kiev, Ukraine .

Adult male

Unknown from the type materials. However , it has been reported on maple ( Acer pseudoplatanus ) in Kremenets region, Ternopol district ( Ukraine), collected and described, for the first time, by Kolodochka (2009).

Previous reports — N. tuberculata is only known from the West-Palaearctic area. Countries from which this species is reported are: Caucasus region ( Abbasova 1966), Croatia ( Tixier et al. 2010), Georgia ( Wainstein 1958), Greece ( Papadoulis and Emmanouel 1997), Moldova (Wainstein 1973), Norway ( Chant and Yoshida-Shaul 1989), and Ukraine ( Kolodochka 1981, 2009). Plants on which N. tuberculata was reported are: A. pseudoplatanus , Acer sp., A. steveni Pojark. (Aceraceae) ; A. hippocastanum (Hippocastanaceae) ; Artemisia sp. ( Asteraceae ); Cydonia sp., P. armeniaca , Prunus (cerasus) sp.; Rubus sp. ( Rosaceae ); J. regia (Juglandaceae) ; Ribes sp. ( Grossulariaceae ); Zelkova sp. ( Ulmaceae ). This species was recently collected in the Massif Central ( France), on A. platanoides .
