Diagnosis (female)

Dorsal setae different in shape, three pairs of caudal setae (h1, h2 and ps1) spatulate, propodosomal trichobotria approximately thick and not much longer than the other dorsal setae. Palpal tarsus length (20) subequal to cheliceral stilettos (19), solenidion ωI shorter than half of tarsus I width, setae of genua III-IV and dorsal seta on tibiae III are stout and blunt distally.

Female ( Figs. 23–28 View Figures 23–25 View Figures 26–28 )

Body oval shape 355–467 length (excluding gnathosoma), width 214–222 (at level of seta c2).

Dorsum – Completely striated ( Fig. 23 View Figures 23–25 ), dorsal setae spindle and serrated, length of dorsal setae: bo 34–36, ro 29–31, la 24–26, ex 31–33, c1 25–27, c2 32–35, d1 26–28, e1 30 –33, f1 32–34, f2 36–43, h1 31–33, h2 30–32, ps1 20–21. Distances between dorsal setae: ro -ro 28–31, la -la 85– 94, bo -bo 60–65, c1-c1 64–69, c2-c2 170–181, d1-d1 43–48, e1-e1 103–111, f1-f1 30–35, f2-f2 79– 86, h1-h1 26–30, h2-h2 56–63, ps1-ps1 25–29.

Venter – Ventral cuticle and coxisternal shields striated ( Fig. 26 View Figures 26–28 ), lengths of ventral setae: 1b 27–28, 1c 24–26, 2a 19–21, 3b 29–32, 3c 25–27, 3d 26–27, 4b 24–25, pt 29–31, mtα 19–20, mtβ 17–18, ag1 14, ag2 16–17, ag3 16–17, ag4 17, ps3 24–26.

Gnathosoma – Visible completely from above. Palpal femur-genu: length 23, width 12. Palp distally with eupathidium (pζ) straight, 8 long. Palp chaetotaxy (6+ ω –1–2) ( Fig. 4 View Figures 1–7 ).

Legs – Measurements from trochanter to tarsus (excluding pretarsus): leg I 197–205; leg II 170–176; leg III 183–187; leg IV 207–214; cg (coxal organ) narrowed, oval shape. Measurements: tarsus + apotele I length/width: 65/14. Length of setae on tarsus I: ft’ζ 18–20, ft”ζ 31–33, tc’ζ 19– 20, tc”ζ 28–31, ωI 6 ( Fig. 25 View Figures 23–25 ). Tarsus II with club-like solenidion ωII 2 long. Setae of genua III-IV and dorsal seta on tibiae III stout and blunt distally ( Figs. 27, 28 View Figures 26–28 ).

Remarks

It is the first record of this species in Hamedan and Lorestan provinces. Re-description of T. goetzi   in this study resembles previous studies by Baker (1970) and Darbemamieh et al. (2016). Unlike previous studies, more detail and measurements of body setae are presented in this study. Setae of genua III-IV and dorsal seta on tibiae III are blunt in this re-description, but according to former study dorsal setae of genua III and tibiae III-IV are blunt.
