Description
Male. Somatic characters see Fig. 7A–C, and Miller et al. 2009[1]: 56.
Measurements: Total length 2.22. Carapace 1.10 long, 1.00 wide. Clypeus 0.25 high. Sternum 0.58 long, 0.60 wide. Abdomen 1.13 long, 0.99 wide. Length of legs: I 6.95 (2.10, 0.66, 1.79, 1.25, 1.15); II 5.88 (1.82, 0.57, 1.45, 1.12, 0.92); III 3.96 (1.31, 0.39, 0.86, 0.74, 0.66); IV 4.24 (1.42, 0.40, 0.96, 0.83, 0.63).
Male palp (Fig. 8A–F): Femur long, curved mesially (Fig. 8E, F); patella elongate, with a distal-dorsal spine (Fig. 8E, F); tibia swollen, longer than patella, bearing dense stiff dorsal setae and 2 dorsal trichobothrium proximally, 2 long ventral setae distally (Fig. 8A: TiS). Cymbium broad, covers ventral part of bulb, dorsal part exposed (Fig. 8A–C). Paracymbium with long thick setae (Fig. 8C). Cymbial apophysis small hooked, sclerotized, on prolateral surface of cymbium (Fig. 8A–C). Cymbial conductor translucent, falcate, bearing dense cluster of long setae on prolateral face (Fig. 8C). Tegulum smooth, without process; spermatic duct long, twisted on base of embolus (Fig. 8D). Embolus long, wire-like, with proximal origin (Fig. 8B, D).
Female
Somatic characters see Fig. 7D–F, and Miller et al. 2009[1]: 56.
Measurements: Total length 2.48. Carapace 1.16 long, 1.12 wide. Clypeus 0.25 high. Sternum 0.64 long, 0.63 wide. Abdomen 1.43 long, 1.30 wide. Length of legs: I 6.66 (1.96, 0.64, 1.64, 1.31, 1.11); II 5.81 (1.73, 0.62, 1.36, 1.13, 0.97); III 3.98 (1.27, 0.40, 0.85, 0.78, 0.68); IV 4.69 (1.50, 0.66, 1.03, 0.85, 0.65).
Vulva (Fig. 9A–D): Scape relatively narrow basally (Fig. 9A, C), with gently notched lateral margins (Fig. 9D) and moderately curved dorsal profile (Fig. 9B). Lateral margins of scape proximal to notches are nearly parallel (Fig. 9C, D).
Distribution
Known from a single cave in Yunnan, China.
Natural history and web architecture
This species lives in the dark zone of the cave. The web documented in Fig. 10B resembles that of Y. kehen, except that it is under less tension, causing lines in the superstructure to bow. The occupant of this web was observed below the catching spiral.
