Peritreme. Short, extending to between setae z3–z4. Venter (Figure 13). Ventral setal pattern 15:JV:ZV. Sternal shield smooth, lightly sclerotised; with two pairs of setae (ST1 and ST2) and two pairs of pores (iv1 and iv2); length (ST1–ST2) 41 (40–42), width (distance between setae ST2) 60; setae ST3 situated on separate platelets; metasternal setae ST4 and pair of pores (iv3) on metasternal shields. Genital shield smooth, width at level of genital setae (ST5) 63 (61–64), para-genital poroids iv5 on integument. Ventrianal shield pentagonal, striated. Four pairs of pre-anal setae (JV1, JV2, JV3 and ZV2), seta ZV2 out of shield on left side; and pair of widely separated and small rounded solenostomes (gv3) posteromesad setae JV3, distance between pre-anal pores 54 (53–54). Pair of para-anal (Pa) and post-anal setae (Pst) present. Length of ventrianal shield 114 (113–115), width at level of setae ZV2 101 (99–102). Setae ZV1, ZV3, JV4, JV5 and four pairs of poroids on integument surrounding ventrianal shield. Setae JV5 smooth, 34 (33–34) in length. Gnathosoma. Anterior margin of epistome rounded and smooth. Hypostomal groove with seven transverse rows of denticles, each row with two or three teeth; subcapitular setae h1 19 (18–19), h2 19 (18–19) and h3 18, slightly shorter than palp coxal setae (pc) 23 (22–23). Chaetotaxy of palps similar to new species described above. Chelicera (Figure 14). Fixed digit 28 (27–28) long, with five teeth and pilus dentilis; movable digit 27 (26–27) long with one tooth. Spermatheca (Figure 15). Calyx bell-shaped, flaring distally, 13 (12–13) in length; atrium incorporated within calyx. Legs (Figures 16, 17). Length of legs (base of coxae to base of claws): leg I 301 (294–307); leg II 262 (259– 265); leg III 273 (272–274); leg IV 342 (339–344). Chaetotaxy of legs similar to new species except genu II 2 2/0 2/0 1. Apical sensorial setal cluster of tarsus I with five modified setae with different shapes. Leg IV with one blunttip macroseta, knob absent, StIV 45 (44–45). Other legs without macrosetae. Male. Unknown. World distribution. Canada (Chant & Yoshida-Shaul, 1978), and Russia (this study).
