Female– One specimen measured.
Idiosomal setal pattern: 10A:8E/JV–3:ZV.
Dorsal idiosoma (Fig. 6A) – Dorsal shield 365 long and 248 wide at j 6 level smooth with a pair of strips between j 3 and Z 5, with 18 pairs of dorsal setae (r 3 and R 1 included); dorsal shield setae smooth, except for Z 4 and Z 5, slightly serrated; lengths: j 1 19, j 3 28, j 4 4–6, j 5 4–6, j 6 4–6, J 5 8, z 2 13, z 4 10, z 5 4–6, Z 1 4–6, Z 4 93, Z 5 122, s 4 66, S 2 4 –6, S 4 8, S5 9; setae r 3 13 and R 1 10 on lateral integument; Z 4, Z 5 and s 4 are the longest; dorsal shield with 7 pairs of solenostomes (gd 1, gd 2, gd 4, gd 5, gd 6, gd 8, gd 9) and 12 pairs of small poroids. Setae z 2 slightly longer than z 4.
Peritreme – Extending almost beyond setae j 1 (Fig. 6A).
Ventral idiosoma (Fig. 6B) – Sternal shield wider than long, posterior margin slightly concave, smooth with a few lateral striae, 62 long, 80 wide at level of setae ST 2, three pairs of setae and two pairs of pores (iv 1 and iv 2), ST 1 30, ST 2 28, ST 3 27; distances between ST 1 –ST 3 62, ST 1 –ST 1 51 and ST 2 –ST 2 66; metasternal setae ST 4 27 and a pair of pores (iv 3) on small platelets (metasternal shields); genital shield smooth width at widest point 81, ST 5 28; two pairs of metapodal shields, primary 25 long and accessory 13 long; ventrianal shield pentagonal (Fig. 6B), reticulated all over but slightly darker at the edges, length 111, width at level of setae ZV 2, 103, and width at level of paranal setae 71; with three pairs of preanal setae (JV 1 20, JV 2 19, ZV 2 19); four pairs of setae surrounding ventrianal shield on integument (JV 4 13, JV 5 51, ZV 1 17, ZV 3 13), five pairs of pores and one pair of small platelets surrounding ventrianal shield. Ventrianal shield with a pair of small round pores (gv 3) posteromesad to JV 2, distance between these pores 42.
Spermatheca – Calyx cup shaped 6 long, 13 in diameter at the middle part of the calyx; atrium U-shaped (Fig. 6C).
Chelicera – Fixed digit 28 long with 10 teeth and a pilus dentilis; movable digit 32 long with 2 teeth (Fig. 6D).
Legs –LegIV(Fig.6E) withthreepointedmacrosetae, SgeIV 68, StiIV 47, StIV 63; length of macrosetae on other legs: SgeIII 32, SgeII 25; leg I with no recognizable macrosetae; length of legs from the base of coxae to the tip of claws: leg I 373, leg II 295, leg III 293, leg IV 385; 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 (1-2/0, 2/1-1) 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 – Germany, Greece, Norway, Russia and The Netherlands (this study).
Specimen examined – One female, 29 June 2018, soil of a grassland meadow, situated near the village of Beuningen, The Netherlands (51°50’11.33”N 5°45’01.57”E), collector: Bogdan Dehelean.
Remarks – This is a new species record for Dutch fauna. The morphological characters and measurements of the specimen collected from The Netherlands fit well with those re-described by Faraji et al. (2018) from Germany. Proprioseiopsis sharovi can be easily identified by the unique shape of its spermatheca.
