Griswold, CGY11 (CASENT 9020739, HNU), 1 &amp;female;, 4 juvs; [same data] (CASENT 9020738, HNU), 2 &amp;female;; [same data] (CASENT 9029290, CAS), 2 &amp;female;. <b>Etymology.</b> Formed from the Chinese words for bamboo shoot (zhú sǔn), referring to the macrosetae on the front of the male chelicerae in <i>Gaoligonga zhusun</i> that are much smaller than those in <i>G. changya</i>, the other species in this genus. <b>Diagnosis.</b> Male distinguished by the much weaker pair of macrosetae near the base of each chelicerae (Fig. 46D) compared to <i>G. changya</i> (Figs 38A, 40 E-F); further distinguished by the shape of the embolic tip (expanded in <i>G. zhusun</i>, Fig. 46B; tapered in <i>G. changya</i>, Fig. 40C) and by the lack of a cymbial tooth (present in <i>G. changya</i>, Fig. 40B). Female distinguished by the nearly longigudinal spermatheca/copulatory duct complex (Fig. 43E; <i>G</i>. changya has spermathecae distinct from sinuous copulatory ducts, Fig. 43B); further distinguished by the well sclerotized ventral plate of the epigynum in <i>G. changya</i> (Fig. 43A), less strongly sclerotized in <i>G. zhusun</i> (Fig. 43D). <b>Description.</b> Carapace yellow to brown, male head region moderately raised, sulci absent (Fig. 46E). Male chelicerae with four moderately strong setae rooted near the base (Fig. 46D). Sternum dark brown with light median stripe. Legs yellow with dark rings distally on tibiae and metatarsi. Femoral spots absent. Abdomen brown with numerous tan spots, with two large and up to six small dorsal white spots, and pair of unjoined longitudinal white lines laterally; posterior tubercle absent (Fig. 44). Male palp: Embolus spiral, tip widened and membranous, not wrapped by distal part of cymbium (Figs 45B, 46B). Tooth-like process on retrolateral part absent from cymbium. Vulva: Epigynum with weakly sclerotized, raised, ridged central knob (Figs 43D, 47D). Spermathecae and copulatory ducts not clearly differentiated, form nearly longitudinal complex (Fig. 43E). Fertilization ducts emerge from posterior part, spiral mesally. Male (CASENT 9020723): Total length 0.67, carapace 0.31 long, 0.31 wide, clypeus 0.15, sternum 0.22 long, 0.22 wide, coxa IV separated by 2.40 times their width. Macrosetae: Leg I: patella d1, tibia d1, metatarsus p1; Leg II: patella d1, tibia d1; Leg III: patella d1, tibia d1; Leg IV: patella d1, tibia d1. Metatarsal macrosetae nearly straight, only slightly kinked near center, metatarsus not excavated prolaterally (Fig. 46F). Metatarsal trichobothria: TmI: 0.22; TmII: 0.29; TmIII: 0.31. Leg measurements: see Appendix A. Epiandrous gland spigots in two widely spaced clusters of two to three spigots each (Fig. 47E). Female (CASENT 9020723): Total length 0.93, carapace 0.38 long, 0.38 wide, clypeus 0.09, sternum 0.26 long, 0.25 wide, coxa IV separated by 2.00 times their width. Macrosetae: 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: 0.26; TmII: 0.31; TmIII: 0.34. Leg measurements: see Appendix A. Spinnerets (Fig. 47 A-C).
