Etymology. Formed from the Chinese words for bamboo shoot (zhú sǔn), referring to the macrosetae on the front of the male chelicerae in Gaoligonga zhusun that are much smaller than those in G. changya , the other species in this genus.

Diagnosis. Male distinguished by the much weaker pair of macrosetae near the base of each chelicerae ( Fig. 46D View Figure 46 ) compared to G. changya ( Figs 38A View Figure 38 , 40 View Figure 40 E-F); further distinguished by the shape of the embolic tip (expanded in G. zhusun , Fig. 46B View Figure 46 ; tapered in G. changya , Fig. 40C View Figure 40 ) and by the lack of a cymbial tooth (present in G. changya , Fig. 40B View Figure 40 ). Female distinguished by the nearly longigudinal spermatheca/copulatory duct complex ( Fig. 43E; G View Figure 43 . changya has spermathecae distinct from sinuous copulatory ducts, Fig. 43B View Figure 43 ); further distinguished by the well sclerotized ventral plate of the epigynum in G. changya ( Fig. 43A View Figure 43 ), less strongly sclerotized in G. zhusun ( Fig. 43D View Figure 43 ).

Description. Carapace yellow to brown, male head region moderately raised, sulci absent ( Fig. 46E View Figure 46 ). Male chelicerae with four moderately strong setae rooted near the base ( Fig. 46D View Figure 46 ). 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 View Figure 44 ).

Male palp: Embolus spiral, tip widened and membranous, not wrapped by distal part of cymbium ( Figs 45B View Figure 45 , 46B View Figure 46 ). Tooth-like process on retrolateral part absent from cymbium.

Vulva: Epigynum with weakly sclerotized, raised, ridged central knob ( Figs 43D View Figure 43 , 47D View Figure 47 ). Spermathecae and copulatory ducts not clearly differentiated, form nearly longitudinal complex ( Fig. 43E View Figure 43 ). 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 View Figure 46 ). 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 View Figure 47 ).

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 View Figure 47 A-C).
