Dorsum. Dorsal shield 335 long, 174 wide at level of s4, 185 at level of S2, 187 at level of S4; dorso-central area slightly reticulated and lateral areas stronger reticulation, with four solenostomes (gd2, gd6, gd8, gd9), 17 pairs of dorsal setae and two pairs of sub-lateral setae: j1 20; j3 26; j4 15; j5 16; j6 17; J2 16; J5 9; z2 17; z3 21; z4 19; z5 17; Z4 34; Z5 53; s4 22; s6 23; S2 26; S4 29; S5 30; r3 23; R1 22. All setae smooth, except Z5, slightly serrated. Peritreme extending forward at level between the bases of the setae j1–j3 or j3–z2.

Ventral idiosoma. Sternal shield with two pairs of setae (st1, st2) and poroids iv1 and iv2. Distances between setae st1–st1 45, 46, st2–st2 49, st1–st2 36. Setae st3 and st4 tylochorous (on platelets). Genital sigilla (1–3 pairs) clearly visible on the genital shield. Posterior margin of the scutum straight. The 4 th and 5 th pairs of genital sigilla sometimes visible between the bases of the setae ZV1. The 6 th pair of sigilla (sgpa) filiform, curved postero-paraxial to the setae ZV1. Ventrianal shield sub-triangular, slightly striated with anterior margin almost convex. Ventrianal shield 95 long, width at level of setae ZV2 90, at level of setae JV2 74, at level of setae JV3 79 and at level of paraanal setae 60. Four pairs of pre-anal setae, JV1, JV2, JV3 and ZV2 and no solenostomes gv3. Setae JV5 smooth, 39 long.

Chelicera. Fixed digit 30 long, with four teeth, three of them between the pilus dentilis and the apical tooth and one posterior to the pilus dentilis. Movable digit, unidentate, 29 long.

Legs. Genu II with seven setae, 2 2/0 2/0 1; Legs IV with a slightly rounded-tip macroseta on the basitarsus, StIV 40 long and enlarged setae on genu (22) and tibia (26).

Insemination apparatus. Major duct broad and short (4). Accessus sometimes visible. Atrium bulbous, embolus and minor duct visible. A long neck (12) is present between the atrium and the calyx. Calyx cup-shaped or campanulate, 8 long and 7 wide.

Remarks. This is the first report of this species from France. It has been observed on Abies sp. in Greece and Ukraine.
