Griswold, D. Kavanaugh, K. Guo, CGY102 (CASENT 9022329, HNU), 1&amp;female;. Paratypes: [same data as holotype] (CASENT 9022327, CAS), 1&amp;female;; [same data as holotype] (CASENT 9029325, HNU), 1&amp;female;. <b>Etymology.</b> Formed from the Chinese word for very small (xiǎo xiǎo); this is the smallest spider known from the Gaoligongshan. <b>Diagnosis.</b> Among <i>Patu</i> species with only one cheliceral tooth, female <i>P. xiaoxiao</i> and <i>P. qiqi</i> are distinguished from <i>P. woodwardi</i> (female unknown in <i>P. marplesi</i>) by the internal genitalia, spermathecae round and juxtaposed in <i>P. woodwardi</i> (Forster 1959: fig. 123), spermatheca/duct complexes clearly separated in <i>P. xiaoxiao</i> (Fig. 67H) and <i>P. qiqi</i> (Fig. 67F); distinguished from <i>P. jidanweishi</i> by the absence of a scape (Fig. 67B); <i>P. xiaoxiao</i> distinguished from <i>P. qiqi</i> by the elongate longitudinal axis of the spermatheca/duct complex in <i>P. xiaoxiao</i> (Fig. 67H; looped path in <i>P. qiqi</i>: Fig. 67F). In ventral view, the epigynum of <i>P. xiaoxiao</i> has two indistinct comma-shaped structures showing through the integument (Fig. 67G; two juxtaposed dark circles showing through the integument in <i>P. qiqi</i>: Fig. 67E). <b>Description.</b> Carapace light brown with darker patches. Six eyes in three doublets. Sternum dark brown. Chelicerae fused for about half their length, with single prolateral tooth, fang furrow absent. Female palp absent. Legs brown. Abdomen mottled dark gray, lighter dorsally. Vulva: Scape absent, two comma-shaped structures visible through integument near epigastric furrow (Fig. 67G). Spermatheca/duct complex longitudinal leading to pair of curved atria diverging anteriorly (Fig. 67H). Female (CASENT 9022329): Total length 0.61, carapace 0.26 long, 0.28 wide, clypeus 0.04, sternum 0.19 long, 0.18 wide, coxa IV separated by 2.10 times their width. Leg I: patella d1, tibia d1; Leg II: patella d1, tibia d1; Leg III: patella d1, tibia d1; Leg IV: patella d1, tibia d1. Metatarsal trichobothria: TmI: 0.44; TmII: 0.48; TmIII: 0.47. Leg measurements: see Appendix A. Male unknown.
