( Figs 15–16 , 36 )

Type material: Holotype: female, CHINA, Yunnan, Gongshan County, Dulongjiang Township, 0.6 km N of Dizhengdang Village, Dulong river, 28.08442°N, 98.32652°E, 1880 m, 29 2004, David Kavanaugh, Da-zhi Dong & Guo Tang (HNU-DHK-2004-059B).

Paratypes: CHINA, Yunnan: 1 female; same data as holotype; 1 female, Gongshan County, Dulongjiang Township, Longyuan Village, Bailai Group, 28º00ʹ33.0ʹ N, 98º19ʹ19.8ʹ E, 1676 m, 31 October to 3 November 2004, Guo Tang (HNU-Tang-04-06); 1 female, Fugong County, Lumadeng Township, near Shibali forest station, 27.16894°N, 98.77205°E, 2650 m, 9 May 2004, Charles Griswold & Heng-mei Yan (HNU-CGY41); 2 females, Gongshan County, Dulongjiang Township, Dizhengdang Village, 28.04430ºN, 98.19322ºE, 1841 m, 27-30 October Guo Tang (HNU-Tang-04-05).

Etymology. The specific name comes from the Latin word “ foliacea ”, meaning “foliiform”, and refers to the shape of brown portion in the median stripe of abdominal dorsum.

Diagnosis. This species can be distinguished from other Wolongia species by the combination of the following characters: 1) copulatory opening located at the posterior half of the atrium ( Figs 13 C, 14B); 2) spermatheca membranous, slightly longer than wide in dorsal view ( Figs 13 D, 14C); 3) atria connected ( Figs 13 C, 14B). This species is similar to W. mutica n. sp. in having larger atrium ( Figs 13 C, 14B, 20B, 22A), but differs in: 1) copulatory opening located at the posterior half of the atrium versus at the top of atrium in W. mutica n. sp. ( Figs 20 B, 22A); 2) spermatheca slightly longer than wide in dorsal view versus three times longer than wide in W. mutica n. sp. ( Figs 20 C, 22B).

Description. Female (holotype): Total length 3.10. Cephalothorax 1.25 long, 1.05 wide. Abdomen 2.10 long, 1.53 wide. Carapace yellow-brown, with dark margins. AME 0.08, ALE 0.10, PME 0.08, PLE 0.10, AME- AME=AME-ALE (0.08), PME-PME=PME-PLE (0.10), LMOA 0.25, AWMOA 0.23, PWMOA 0.28. Clypeus 0.13. Chelicerae yellow-brown, with 5 retromarginal teeth ( Figs 1 D, 14A). Labium brown, width 0.29, length 0.16. Coxae yellow-brown. Legs yellow-brown. Leg measurements: I 6.93 (1.88, 2.30, 2.00, 0.75), II 5.03 (1.50, 1.75, 1.41, 0.37), III 3.22 (0.95, 0.86, 0.66, 0.75), IV 4.07 (1.30, 1.29, 1.05, 0.43). Abdomen oval, widest medially. Dorsum yellowish, with a longitudinal median stripe and five pairs of brown foliiform patterns ( Fig. 13 A). Venter yellow brown, with many small white spots. Atria connected ( Figs 13 C, 14B); copulatory openings located at the posterior half of the atrium ( Figs 13 C, 14B); spermathecae membranous, slightly longer than wide in dorsal view ( Figs 13 D, 14C).

Male Unknown.
