Cymbium broad, covers ventral part of bulb, dorsal part exposed ( Fig. 8 A–C View Figure 8 ). Paracymbium with long thick setae ( Fig. 8 C View Figure 8 ). Cymbial apophysis small hooked, sclerotized, on prolateral surface of cymbium ( Fig. 8 A–C View Figure 8 ). Cymbial conductor translucent, falcate, bearing dense cluster of long setae on prolateral face ( Fig. 8 C View Figure 8 ). Tegulum smooth, without process; spermatic duct long, twisted on base of embolus ( Fig. 8 D View Figure 8 ). Embolus long, wire-like, with proximal origin ( Fig. 8 B, D View Figure 8 ).

Female.

Somatic characters see Fig. 7 D–F View Figure 7 , and Miller et al. 2009: 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).

Lateral margins of scape proximal to notches are nearly parallel ( Fig. 9 C, D View Figure 9 ).

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 View Figure 10 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.
