Peritreme – Extending to level of setae j 3 ( Fig. 1A ).

Ventral idiosoma ( Fig. 1B ) – Sternal shield smooth, posterior margin not visible, 64 (63–65) wide at level of setae ST 2, with three pairs of setae and two pairs of pores (iv 1 and iv 2), ST 1 30–32, ST 2 28–30, ST 3 28–30; distances between ST 1 –ST 3 56 (55–57) and ST 1 –ST 1 45 (44–47), ST 2 –ST 2 58 (57–58); metasternal setae ST 4 28–29 and a pair of pores (iv 3) on small platelets; genital shield smooth width at widest point 81 (79–82), ST 5 23–24; two pairs of narrow metapodal shields, primary 28 (26–30) long and accessory 8–10 long; ventrianal shield relatively small ( Fig. 1B ), smooth, length 81 (79–82), width at level of setae ZV 2, 39 (38–40), and width at level of paranal setae 44 (44–45); with one pair of preanal setae (JV 2 16–17), one specimen exceptionally with two pairs of preanal setae ( Fig. 1E ); six pairs of setae surrounding ventrianal shield on integument (JV 1 16–17, JV 4 10–13, JV 5 25 (24– 27), ZV 1 16–17, ZV 2 15–16, ZV 3 8–10), five pairs of pores and two pairs of small platelets surrounding ventrianal shield. Ventrianal shield with a pair of small round pores posteriad to JV 2 wider apart than the distance between setae JV 2 insertions, distance between these pores 28.

Spermatheca – Calyx cup-shaped 4–5 long, 10–11 in diameter of the calyx; atrium nodular c-shaped ( Fig. 1C ).

Chelicera – Fixed digit 24 long with 2 or 3 apical teeth (apical hook is not considered) and a pilus dentilis; movable digit 25 long smooth ( Fig. 1D ).

Legs – Leg IV ( Fig. 1F ) with one short and barbed macroseta, StIV 17 (16–18), some dorsal setae of legs are barbed; legs I, II and III with no recognizable macrosetae; length of legs from the base of coxae to the tip of claws: leg I 258 (255–261), leg II 223 (220–230), leg III 216 (208–225), leg IV 294 (285–299); chaetotactic formulae of genua and tibiae I–II–III–IV with 10 (2-2/1, 2/1-2) – 8 (2-2/1, 2/0-1) – 7 (1-2/1, 2/0-1) – 8 (2-2/1, 2/0-1) and 10 (2-2/1, 2/1-2) – 7 (1-1/1, 2/1-1) – 7 (1-1/1, 2/1-1) – 7 (1- 1/1, 2/0-2) setae respectively.

Distribution – Greece and The Netherlands (this study).

Specimen examined – Twenty females, 10 September 2014, Salix cinerea , Science park , Amsterdam, The Netherlands (52°21’20.8”N 4°57’34.2”E), collector: Farid Faraji.

Remarks – This is a new species record for Dutch fauna. All the morphological features of the Dutch specimens fit well with those described by Papadoulis et al. (2009). There are four features which were not indicated in the original description: fixed digit of chelicera with 2 or 3 teeth, JV 5 and StIV serrated, presence of idl3 on dorsal shield and ventrianal shield rarely having 2 preanal setae.
