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. AME 0.07, ALE=PME=PLE (0.08), AME-AME=AME-ALE (0.05), PME- PME>PME-PLE (0.08>0.06), LMOA 0.21, AWMOA 0.16, PWMOA 0.21. Clypeus 0.13. 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).

Male Unknown.
