Etymology.Formed from the Chinese word for tusk (cháng yá), referring to the prominent macrosetae on the front of the male chelicerae.
Diagnosis.Male distinguished by the presence of two strong macrosetae near the base of each chelicerae ( Figs 38A, 40E-F); further distinguished by the shape of the embolic tip (tapered in G. changya, Fig. 40C; expanded in G. zhusun, Fig. 46B) and by the presence of a cymbial tooth ( Fig. 40B; absent in G. zhusun). Female distinguished by the well sclerotized ventral plate of the epigynum with ridges radiating out from a raised knob (Figs 41A, 43A), reniform spermathecae, and sinuous ducts ( Fig. 43B; epigynum and raised knob less strongly sclerotized in G. zhusun, spermathecae not strongly differentiated from nearly longitudinal ducts; Figs 43D-E, 47D).
Description.Carapace brown with darker patches in thoracic and head regions, male covered with elongate, flat tubercles, head region raised, sulci absent ( Fig. 40E). Male chelicerae each with a pair of very strong macrosetae rooted near the base ( Fig. 38A, 40E-F). Labrum weakly sclerotized; labral tongue present, base not produced into a labral spur (Fig. 41E-F). Sternum yellow with broad dusky margin. Legs yellow with dark rings distally on tibiae and metatarsi. Femoral spots absent. Abdomen brown with tan and white spots; posterior tubercle absent ( Fig. 38). Male palp: Embolus spiral, follows margin of cymbium to tip, embolus tip wrapped by distal part of cymbium ( Fig. 40C). Cymbium with a tooth-like process on retrolateral part ( Fig. 40B). Vulva: Epigynumwith semicircular ridges radiating out from raised knob (Fig. 41A). Ventral plate heavily sclerotized, red ( Fig. 43A). Spermathecae and ducts all heavily sclerotized ( Fig. 43B). Spermathecae reniform. Copulatory ducts thick, follow simple curved path. Fertilization ducts run posteriorly and mesally, then turn anteriorly near tips. Male (CASENT 9022509): Total length 0.83, carapace 0.38 long, 0.42 wide, clypeus 0.24, sternum 0.28 long, 0.26 wide, coxa IV separated by 1.64 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 kinked beyond center, region beyond macroseta excavated prolaterally ( Fig. 40D). Metatarsal trichobothria: TmI: 0.25; TmII: 0.26; TmIII: 0.35. Leg measurements: see Appendix A. Epiandrous gland spigots in two widely spaced clusters of three spigots each (Fig. 41C). Posterior lateral spinnerets with flagelliform and aggregate gland spigots reduced to nubbins ( Fig. 42F). Female (CASENT 9016244): Total length 1.13, carapace 0.45 long, 0.45 wide, clypeus 0.10, sternum 0.30 long, 0.30 wide, coxa IV separated by 1.75 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: 0.27; TmII: 0.28; TmIII: 0.34. Leg measurements: see Appendix A. Spinnerets ( Fig. 42A-D). NaturalHistory.This species builds a three-dimensional spherical web typical of the Mysmenidae( Fig. 26B-D; see also page 12).
