Legs – Leg IV ( Fig. 4E ) with three pointed macrosetae, SgeIV 89 (87–91), StiIV 72 (70–76), StIV 65 (65–66); length of macrosetae on other legs: SgeI 31 (30–32), SgeII 38 (37–40), SgeIII 42 (40–45); length of legs from the base of coxae to the tip of claws: leg I 411 (402–420), leg II 319 (307–330), leg III 310 (305–315), leg IV 417 (415–418); chaetotactic formulae of genua and tibiae I–II–III–IV with 10 (2-2/1, 2/1-2) – 7 (2-2/0, 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 (1-2/1, 1/1-1) – 7 (1-1/1, 2/1-1) – 6 (1-1/0, 2/1-1) setae respectively. Distribution – Algeria , Azerbaijan, Canada , France , Germany , Greece , Hungary , Iceland , Iran , Italy , Latvia , Moldova , Morocco , Poland , Spain , Switzerland , The Netherlands , Tunisia , Turkey , Ukraine and USA . Specimen examined – Five females , 28 June 2010 , unidentified weeds from a grassland, Sinderhoeve , near Renkum , The Netherlands ( 51°59’52.9”N 5°45’15.9”E ), collector: Frank Bakker. Figure 5 . Proprioseiopsis gallus Karg (Female): ( A ) Idiosoma, dorsal view; ( B ) Idiosoma, ventral view; ( C ) Spermathecae; ( D ) Chelicera; ( E ) Leg IV. Remarks – The characteristics of the specimens found in The Netherlands fits well with the re-descriptions of this species. Faraji et al. (2008 , 2011 ) mentioned the movable digit of chelicera with one minute tooth while the Dutch specimens show it smooth.
