Diagnosis (female)

All dorsal setae are similar in shape, long, serrated and somewhat thick. Trichobothrium seta (bo) narrow and less serrated, subequal in length to ro, la, c1, d1 and shorter than other dorsal setae. Genital shield with 6 setae. Palpal tarsus longer than cheliceral stilettos, eupathidium on palp tarsus straight, stae ba very short so that shorter than half of palp tarsus width.

Female ( Figs. 15–19 View Figures 15–17 View Figures 18–19 )

Body oval 348–370 length (excluding gnathosoma), width 223–238 (at level of seta c2).

Dorsum ( Fig. 15 View Figures 15–17 ) – Completely striated with 13 pair setae, striations longitudinal on prodorsum, between setae c1, striations are U shaped and between setae d1, are V shaped, from d1 up to f1 striations are transverse. Opisthosoma caudally (from base of f1 to end of body) with striae forming an inverted “ V ”–pattern. Length of dorsal setae: bo 35–41, ro 32–40, la 33–39, ex 41–50, c1 25–27, c2 33–40, d1 35–40, e1 44 –51, f1 45–52, f2 47–52, h1 45–51, h2 43–50, ps1 27–30. Distances between dorsal setae: ro -ro 22–29, la -la 95–110, bo -bo 60–71, c1-c1 69–80, c2-c2 195– 210, d1-d1 52–58, e1-e1 115–126, f1-f1 25–32, f2-f2 73–80, h1-h1 26–30, h2-h2 58–62, ps1-ps1 25–29. Lyrifissures ia and im in dorsal (posteriorly to c2 and anterior of e1) and ih in ventral surface (posterior to anal opening) of hysterosoma   .

Venter – Ventral cuticle and coxisternal shields striated, striations between pt setae longitudinal, between pt up to mtα transverse and between mtα up to mtβ are longitudinal ( Fig. 18 View Figures 18–19 ). Lengths of ventral setae: 1b 28–31, 1c 27–29, 2a 25–28, 3b 31–34, 3c 25–28, 3d 25–27, 4b 24–26, pt 27–31, mtα 17–19, mtβ 17–20, ag1 15–17, ag2 15–17, ag3 14-16, ag4 16–18, ps3 21–23.

Gnathosoma – Not visible completely from above. Subcapitulum with striae oblique, Sc1 8– 10, Sc2 29–33. Palpal femur-genu: length 29, width 12. Palp distally with eupathidium (pζ) straight, 7 long. Palp chaetotaxy (6+ ω –1–2) ( Fig. 17 View Figures 15–17 ). Cheliceral stiletto 18 shorter than palpal tarsus 20–21 ( Fig. 16 View Figures 15–17 ). Legs measurements from trochanter to tarsus (excluding pretarsus): leg I 202–213; leg II 183–194; leg III 193–208, leg IV 210–225; coxa I with a coxal organ (cg) stretched circle shape. Measurements: tarsus + apotele I length/width: 72/13. Length of setae on tarsus I: ft’ζ 20–23, ft ” ζ 28–32, tc’ζ 18–20, tc”ζ 33–36, ωI 5 ( Fig. 19 View Figures 18–19 ). Tarsus II with small solenidion not easily to visible, ωII 1 long.

Remarks This redescription resembles original description by Khanjani and Ueckermann (2003), except

that length of some dorsal setae (such as c1, c2, f2) in our study is shorter than original description. Material examined
