Tydeus electus Kuznetzov, 1973

Diagnosis (female)

All dorsal setae are similar in shape, somewhat serrated and long (especially setae on end of opisthosoma). Trichobothrium seta ( bo) is shorter than opisthosomal setae. Genital with 6 setae. Length of palpal tarsus equal to cheliceral stilettos, eupathidium on palp tarsus straight, solenidion

ωI short and very shorter than half of distance between tc -ft and also shorter than half of width of tarsus I.

Body circular to oval shape 400–435 length (excluding gnathosoma), width 270–295 (at level of seta c2).

Dorsum – Completely striated with 13 pairs of setae ( Fig. 20 View Figures 20–22 ), dorsal striation approximately similar to Tydeus caryae . Length of dorsal setae: bo 36–39, ro 26–29, la 27–30, ex 35–39, c1 25– 29, c2 36–39, d1 27–30, e1 35 –38, f1 37–40, f2 41–43, h1 33–36, h2 33–37, ps1 25–27. Distances between dorsal setae: ro -ro 28–31, la -la 123–131, bo -bo 75–80, c1-c1 76–82, c2-c2 235–246, d1-d1 54–58, e1-e1 137–146, f1-f1 43–48, f2-f2 103–112, h1-h1 28–32, h2-h2 61–66, ps1-ps1 25–29.

Venter – Ventral cuticle and coxisternal shields striated. Lengths of ventral setae: 1b 26–28, 1c 24–26, 2a 23–25, 3b 24–25, 3c 24–27, 3d 28–31, 4b 24–25, pt 25–27, mtα 17–19, mtβ 16–18, ag1 15–16, ag2 16–17, ag3 15–17, ag4 17–18, ps3 21–24.

Gnathosoma – Not visible completely from above. Palpal femur-genu: length 29–30, width 12. Palp distally with eupathidium ( pζ) straight, 7 long. Palp chaetotaxy (6+ ω –1–2) ( Fig. 21 View Figures 20–22 ). Length of cheliceral stiletto equal to palpal tarsus, 18.

Legs – Measurements from trochanter to tarsus (excluding pretarsus): leg I 195–203; leg II 192–197; leg III 196–199, leg IV 222–231; Shape of cg (coxal organ) oval. Measurements: tarsus + apotele I length/width: 64/13. Length of setae on tarsus I: ft’ζ 18–20, ft”ζ 33–36, tc’ζ 18–19, tc”ζ 25–28, ωI 5 ( Fig. 22 View Figures 20–22 ). Tarsus II with club-like solenidion ωII 2 long.

Remarks

This re-description resembles the original description by Kuznetzov (1973) in most respects, but in original description length of seta f1 nearly as long as distance f1-h1, while in this study length of f1 clearly shorter than f1-h1.
