The average measurements of the specimens collected are given subsequently.

Idiosoma: length 181 (170–193), maximum width 107 (100–115). Dorsal setae: v1 23 (22–25), sc1 13 (12–13), sc2 60, c1 16 (15–17), c2 25 (24–26), d 10 (10–11), e 11 (10–12), f 16 (15–17), h 13 (12– 14). Distances between setae: v1–v1 22 (21–22), sc2–sc2 45 (45–46), v1 –sc2 35 (33–37), c1–c1 67 (62–69), c2–c2 94 (91–98), c1–c2 27 (27–28), d–d 36 (33–37), f–f 22 (21–23), e– f 28 (27–29), h–h 41 (40–42). Ventral setae: 1a 11, 2a 11 (10–12), 3a 16 (14–17), 3b 8 (8– 9). Tegula, 8 (7–9) long and 9 (9–10) wide. Setae of legs: leg I: 5 (4–6), 1 3, 2 3 (3–4), k 4, d of tibia 26 (23–30); leg II: 5 (4–5), pl’’ 3 (3–4), d of tibia 24 (20­27); leg IV: v’ F 11 (11­12), v’G 17 (15­19), v’Ti 25 (24­27), tc’’ 25 (24­27).

The measurements given by Kaliszewski (1993) based on three specimens from Poland, including the holotype, were: Gnathosoma: length 29­31, width 24­25, pharynx 16 long and 7­8 wide. Idiosoma 197­202 long. Dorsal setae: v1 29 ­32, sc 1 13­15, sc2 64, c1 25, c 2 29­30, d 13, e 13­14, f 17, h 17­18. Distances between setae: v1­v1 2, sc2­sc2 50­ 52, c2­c2 104­111, c1­c2 75­77, d­d 37­42, f­f 24­26, h­h 43­47. Ventral setae: 1a 12, 2a 13­15, 3 a 17, 3 b 12. Setae of legs: leg I: 6­7, 1 4­5; leg II: 4­5, pl’’; leg IV: v’ F 13, v’G 19­22, v’Ti 29­30, tc’’ 60­64.
