Material Examined. Holotype: CHINA: Yunnan: Gaoligong Shan, Nujiang Prefecture: Nujiang State Nature Reserve, QiQi He, 9.9 airkm W of Gongshan, 27.715°N, 98.565°E, 2000 m, 9-14 July 2000, H.-M. Yan, D. Kavanaugh, C.E. Griswold, H.-B. Liang, D. Ubick, & D.-Z. Dong (CASENT 9029328, HNU), 1 ♀.

Paratypes: [same data as holotype] (CASENT 9029326, CAS), 1 ♁, 5 ♀, 1 juv; [same data as holotype] (CASENT 9029327, HNU) 5 ♀, 2 juvs; [same data as holotype] (CASENT 9029329, with prey, CAS), 1 ♀ .

Etymology. Named for the type locality.

Diagnosis. Distinguished from other Patu species except P. woodwardi Forster, 1959, P. marplesi Forster, 1959, P. jidanweishi and P. xiaoxiao by the presence of only a single cheliceral tooth (Forster 1959: fig. 122; two or more in other Patu species); male distinguished from P. woodwardi and P. marplesi by the presence of two ventral subdistal spines on tibia II; distinguished from P. jidanweishi by the short, inflexible embolus in P. qiqi (Fig. 73B; longer and flexible in P. jidanweishi, Fig. 66; male unknown in P. xiaoxiao). Among Patu species with only one cheliceral tooth, female P. qiqi and P. xiaoxiao are distinguished from P. woodwardi (female unknown in P. marplesi) by the internal genitalia, spermathecae round and juxtaposed in P. woodwardi (Forster 1959: fig. 123), spermatheca/duct complexes clearly separated in P. qiqi (Fig. 67F) and P. xiaoxiao (Fig. 67H); distinguished from P. jidanweishi by the absence of a scape (Fig. 67B); P. qiqi distinguished from P. xiaoxiao by the looped path of the spermatheca/ duct complex in P. qiqi (Fig. 67F), elongate along longitudinal axis in P. xiaoxiao (Fig. 67H). In ventral view, the epigynum of P. qiqi has two juxtaposed dark circles showing through the integument (Fig. 67E); P. xiaoxiao has two less distinct comma-shaped structures showing through the integument (Fig. 67G).

Description. Carapace brown. Six eyes in three doublets (Fig. 65G). Sternum dark brown. Chelicerae fused for about half their length, with single anterior tooth, fang furrow absent. Female palp absent. Legs brown. Abdomen medium gray, lighter dorsally (Fig. 65 F-H).

Male palp: Illustrated in Fig. 73. Both palps of the single male specimen are partially expanded and many details of anatomy could not be determined precisely.

Vulva: Scape absent, two circular structures visible through integument near epigastric furrow (Fig. 67E). Spermatheca/duct complex more or less longitudinal with loop near center; duct narrow anteriorly, wider posteriorly (Fig. 67F).

Male (CASENT 9029326): Total length 0.65, carapace 0.27 long, 0.25 wide, clypeus 0.07, sternum 0.19 long, 0.18 wide, coxa IV separated by 2.10 times their width. Leg I: patella d1, tibia d2; Leg II: patella d1, tibia d2, v2; Leg III: patella d1, tibia d1; Leg IV: patella d1, tibia d1. Metatarsal trichobothria: TmI: 0.52; TmII: 0.47; TmIII: 0.44. Leg measurements: see Appendix A.

Female (CASENT 9029326): Total length 0.63, carapace 0.29 long, 0.26 wide, clypeus 0.04, sternum 0.19 long, 0.18 wide, coxa IV separated by 1.91 times their width. Leg I: patella d1, tibia d2; Leg II: patella d1, tibia d2; Leg III: patella d1, tibia d1; Leg IV: patella d1, tibia d1. Metatarsal trichobothria: TmI: 0.45; TmII: 0.43; TmIII: 0.59.
