Type material. Holotype: male, CHINA: GUANGXI: Pingxiang City, Longzhou County, Daqingshan Forestry Center, 22.299° N, 106.700° E, elev. 806–989 m, 15 May 2006, coll. J. Zhang, M. S. Zhu, W. G. Lian & H. Q. Ma, JXZ06#005 (UBC-SEM AR00173). Paratypes: 1 female, same data as holotype (UBC-SEM AR00174); 2 females, same data as holotype.

Etymology. The species name is a noun in apposition referring to the type locality.

Diagnosis. Differs from Foliabitus scutigerus ( Żabka, 1985) , the other species included in this genus, by the wide bulb, the thick embolus and the narrow retrolateral sperm duct loop ( Figs 21–22 ).

Description. Male (holotype, UBC-SEM AR00173). Carapace length 2.3; abdomen length 2.8. Chelicera ( Fig. 23 ): red brown. Palp ( Figs 21–22 ): grayish brown. Proximal tegular lobe indistinct; embolus long and coiled for almost a circle; retrolateral tibial apophysis curved with a small cusp near distal end. First tibia with four pairs of ventral macrosetae; first metatarsus with two pairs of ventral macrosetae. Measurements of legs: I 4.4, II 4.3, III 5.0, IV 5.0. Color in alcohol ( Fig. 19 ): carapace dark brown, relatively smooth; abdomen also dark brown, with an oval slightly sclerotized area, lateral margins with light yellow stripes; first pair of legs reddish brown, other legs yellowish with grayish brown markings.

Female (paratype, UBC-SEM AR00174). Carapace length 2.0 (variation: 2.0–2.2, n=3); abdomen length 3.8. First tibia with four pairs of ventral macrosetae; first metatarsus with two pairs of ventral macrosetae. Measurements of legs: I 4.9, II 4.3, III 4.6, IV 4.7. Epigynum ( Fig. 26 ): with curved grooves within window; median septum narrow and almost reaching anterior edge of window. Vulva ( Fig. 27 ): copulatory duct well sclerotized; spermatheca long and oval. Color in alcohol ( Fig. 20 ): similar to that of male, but abdomen with a medial longitudinal light stripe in addition to the two lateral stripes; first pair of legs yellowish to light orange and other legs without grayish brown markings.
