(Figs 3–6, 35)
Type material: Holotype: male, CHINA, Yunnan, Tengchong County, Jietou Township, 8# boundary post of Yakou, 25.80894°N, 98.62080°E, 2890 m, 23 May 2006, Xian-jin Peng, Xin-ping Wang and Peng Hu (HNU- Wang 060523 (3)).
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).
