Peritreme – Extending to the level of setae j 1 and striated ( Fig. 9A View Figure 9 ).

Ventral idiosoma ( Fig. 9B View Figure 9 ) – Sternal shield wider than long, posterior margin straight, smooth, 53 (48–58) long, 63 wide at level of setae ST 2, two pairs of setae and one pair of pores ( iv 1), ST 1 32–33, ST 2 32; distances between ST 1 –ST 2 34 (32–35), ST 1 –ST 1 46 (45–46) and ST 2 –ST 2 59 (57–60); ST 3 28–32 and iv 2 on a small platelet, metasternal setae ST 4 30– 33 and a pair of pores ( iv 3) on small platelets; genital shield smooth, width at widest point 63 (60–65), ST 5 25–28; two pairs of narrow metapodal shields, primary 44 (41–47) long and accessory 8–13 long; ventrianal shield subrectangular ( Fig. 9B View Figure 9 ), reticulated anterior to anus, length 87 (87–88), width at level of paranal setae 64 (63–65); with one pair of preanal setae ( JV 2 16–20); six pairs of setae surrounding ventrianal shield on integument ( JV 1 20–22, JV 4 11–15, JV 5 32 (27–35), ZV 1 16–19, ZV 2 15–16, ZV 3 8–10), five pairs of pores and one pair of small platelets surrounding ventrianal shield. Ventrianal shield with no pores.

Spermatheca – Calyx saccular 20–24 long, 5–6 in diameter at the middle part of the calyx; atrium inserted at base of the calyx ( Fig. 9C View Figure 9 ).

Chelicera – Due to the closed digits, dentation cannot be seen.

Legs – Leg IV ( Fig. 9D View Figure 9 ) with one relatively short and thick macroseta, StIV 25 (24–25); legs I, II and III with no recognizable macrosetae; length of legs from the base of coxae to the tip of claws: leg I 297 (280–315), leg II 267 (250–283), leg III 258 (245–270), leg IV 335 (320–350); 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) – 7 (1-2/1, 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) – 6 (1-1/1, 2/0-1) setae respectively.

Distribution – Greece, Iran, Moldova, The Netherlands (this study) and Turkey.

Specimen examined – Three females, 27 June 2017, 25 September 2018, in erinea caused by the mite Aceria cerrea on a Quercus cerris ( Turkey Oak), Bos der Onverzettelijken, Almere, Flevoland, Netherlands (52°23’11.0” N 5°14’30.1” E), collector: Paul Hoekstra.

Remarks – This is a new species record for Dutch fauna. The Dutch specimens resemble that of the original description and re-description by Faraji et al. (2007), except seta j 6 is rather longer in the Dutch specimens: 17–23 vs 13 ( Iran) and 12 ( Moldova).
