Paratypes: CHINA, Yunnan: 1 female, Shilali forest station, 27.16519°N, 98.77891°E, 2525 m, 1 May 2004, Charles Griswold & David Kavanaugh (HNU-CGY20); 1 female, Tengchong County, Mingguang Township, Zizhi Village, up slope, 25.80975°N, 98.62081°E, 2880 m, down slope, 25.79808°N, 98.62406°E, 2756 m, 19 May 2006, Chang-min Yin, Jia-fang Hu and Ming-wei Yang (HNU-YHY06).

Etymology. The specific name comes from the combination of prefix “ bi- ” and the Latin word “ macroseta ”, meaning “two” and “macrosetae” respectively, and refers to the two strong macrosetae at the tip of cymbial ectobasal process; adjective.

Diagnosis. This species can be distinguished from other Wolongia species by the combination of the following characters: 1) femur I without rows of short macrosetae prolaterally and ventrally; 2) the longest prolateral seta on Metatarsus I and II about as long as or less than the width of Metatarsus I and II ( Figs 2 B, 10A); 3) conductor with an apophysis subterminally (CSA in Fig. 9 A); 4) tip of the cymbial ectobasal process with two strong macrosetae ( Figs 7 C, 9B); 5) cymbial base with a denticle retrolaterally ( Figs 7 D, 9C); 6) copulatory opening anterior ( Figs 8 B, 10B); 7) spermatheca membranous ( Figs 8 C–E; 10C, E). Males of this species resemble W. guoi Zhu, Kim & Song, 1997 in similar location of the conductor and embolus on the genital bulb ( Figs 7 B, 9A, 15B, 17A), but can be distinguished from the latter by: 1) prolateral and ventral surface of femur I without rows of short macrosetae which is present in W. guoi ( Figs 15 C, F; 18A–B); 3) conductor with an subterminal apophysis which is absent in W. guoi ; 4) tip of cymbial ectobasal process with two strong macrosetae which is absent in W. guoi ; 5) cymbial base with a denticle retrolaterally which is absent in W. guoi . Females are similar to W. renaria n. sp. in habitus, but differ in: 1) copulatory opening anterior versus ventral in W. renaria n. sp. ( Figs 27 B, 28A); 2. spermatheca membranous versus slightly sclerotized in W. renaria n. sp. ( Figs 27 C–D; 28C–D).

Dorsum yellowish-white, with a brown median stripe and six pairs of diagonal stripe-shaped white spots along the margins of stripe ( Fig. 7 A). Venter brown, with a pair of white longitudinal stripes. Cymbial base with a short denticle retrolaterally ( Figs 7 C, 9B); tip of the cymbial ectobasal process with two strong macrosetae in retrolateral view ( Figs 7 C, 9B); conductor and embolus located on upper half of genital bulb ( Figs 7 B, 9A); conductor with an apophysis subterminally ( Figs 7 B, 9A).

Female (paratype): Total length 2.32. Cephalothorax 1.10 long, 0.88 wide. Abdomen 1.34 long, 1.01 wide. General appearance as in male. Leg measurements: I 6.12 (1.81, 1.99, 1.51, 0.81), II 4.77 (1.45, 1.55, 1.13, 0.64), III 2.58 (0.83, 0.81, 0.58, 0.36), IV 3.80 (1.39, 1.15, 0.85, 0.41).
