description: Wolongia erromera new species
(Figs 31–32, 35)
Type material: Holotype: female, CHINA, Yunnan, Nujiang Prefecture, Nujiang State Nature Reserve, Dulong/ Gongshan Yakou area, 21 air km W of Gongshan, 27.69655°N, 98.45389°E, 3300-3680 m, 16-17 July 2000, Hengmei Yan, David Kavanaugh, Charles Griswold, Hong-bin Liang, Darrell Ubick & Da-zhi Dong (HNU-00-BY).
Paratypes: CHINA, Yunnan: 1 female, same data as holotype; 2 females, Fugong County, Lishadi Township, Shibali, 27.10520ºN, 98.77980ºE, 2530 m, 4, 6, 8, 9, 10 August 2005, Guo Tang (HNU-Tang-05-02).
Etymology. The specific name comes from the Latin adjective “ erromera ”, meaning “robust”, and refers to the thickness of the copulatory duct.
Diagnosis. This species can be distinguished from other Wolongia species by the combination of the following characters: 1) the distance between epigastric furrow and copulatory openings about 1/5 long of epigynum in ventral view (Figs 11 B, 12A); 2) atria separated from each other (Figs 11 B, 12A); 3) the top of copulatory duct beyond the top of spermathecae (Figs 11 C, 12C); 4) spermatheca membranous (Figs 11 C, 12C); 5) copulatory ducts pass between the spermathecae (Figs 11 C, 12C). This species is very similar to W. mutica n. sp. in the course of copulatory duct (Figs 11 D, 12C, 20C, 22B), but differs in: 1) atria separated from each other versus connected to each other in W. mutica n. sp. (Figs 20 B, 22A); 2. the top of copulatory duct beyond the top of spermathecae versus only reached to the median position in W. mutica n. sp. (Figs 20 C, 22B).
Description. Female (holotype): Total length 2.51. Cephalothorax 1.00 long, 0.85 wide. Abdomen 1.86 long, 1.50 wide. Carapace yellow-brown.

Chelicerae yellowbrown, with 5 retromarginal teeth (Figs 1 C, 12B). Labium black-brown, width 0.21, length 0.11. Coxae brown. Legs yellow-brown. Leg measurements: I 4.62 (1.30, 1.55, 1.12, 0.65), II 3.64 (1.05, 1.23, 0.85, 0.51), III 2.18 (0.67, 0.65, 0.52, 0.34), IV 3.16 (1.00, 1.01, 0.74, 0.41). Abdomen oval, widest medially. Dorsum yellowish, with a longitudinal brown median stripe (narrower anteriorly, wider posteriorly) and five pairs of white diagonal stripeshaped spots along the stripe (Fig. 11 A). Venter yellowish-white. Atrium close to epigastric furrow (Figs 11 B, 12A); copulatory opening at 1/5 of epigynum length from epigastric furrow in ventral view (Figs 11 B, 12A); spermatheca membranous, suboval in dorsal view (Figs 11 C, 12C); copulatory duct thick (Figs 11 C, 12C).
