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. Leg measurements: see Appendix A.
