Griswold, CGY07 (CASENT 9020741, HNU), 1 &amp;female;. <b>Etymology.</b> Formed from the Chinese words for long (ch&amp;amacr;n) and hook (g&amp;omacr;u zi ), referring to shape of the epigynal scape. <b>Diagnosis.</b> Male distinguished by the trilobate cymbial base (Fig. 17B). Further distinguished from <i>M. goudao</i> by the presence of folds across the cymbial groove (Fig. 17A), as opposed to tubercles in <i>M. guodao</i> (Fig. 29A). Female distinguished from other Chinese mysmenids except <i>Mysmenella pseudojobi</i> Lin &amp; Li, 2008 by the long, soft, wrinkled scape of more or less uniform width from base to rounded tip (Fig. 18B); distinguished from <i>M. pseudojobi</i> by the clear differentiation between bulbous spermathecae and spiral copulatory ducts (Lin and Li 2008: fig. 12F), spermathecae not clearly differentiated from copulatory ducts in <i>M. changouzi</i> (Fig. 11I). <b>Description.</b> Carapace tan with dusky markings, male with weak sulci closer to margin of prosoma than ALE (Fig. 17E-F). Sternum dusky brown. Legs light brown. Femoral spots on legs I and II, indistinct on II in male. Abdomen dark brown with white spots; posterior tubercle absent (Fig. 15A-E). Male palp: Embolus spiral, follows tegular groove for most of length (Fig. 17B), engages with cymbium distally (Fig. 16B). Cymbium with trilobate base on prolateral side (Fig. 17B), middle part with wide shallow groove crossed by transverse striations (Fig. 17A), tip with two lobes (Fig. 17C). Vulva: Epigynum a soft, flexible scape (Figs 11H, 18B). Sclerotized portion of spermatheca/copulatory duct complexes separated by nearly their width (Fig. 11I). Male (CASENT 9006233): Total length 0.68, carapace 0.36 long, 0.35 wide, clypeus 0.10, sternum 0.25 long, 0.25 wide, coxa IV separated by 2.00 times their width. Macrosetae: Leg I: patella d1, tibia d1, metatarsus p1; Leg II: patella d1, tibia d1, v3; Leg III: patella d1, tibia d1; Leg IV: patella d1, tibia d1. Metatarsal macroseta nearly straight, only slightly kinked near center (Fig. 17D). Metatarsal trichobothria: TmI: 0.34; TmII: 0.41; TmIII: 0.29. Leg measurements: see Appendix A. Epiandrous gland spigots in two widely spaced clusters of three spigots each (Fig. 18C). Posterior lateral spinnerets with flagelliform and aggregate gland spigots reduced to nubbins (Fig. 19F). Female (CASENT 9006233): Total length 0.92, carapace 0.41 long, 0.36 wide, clypeus 0.08, sternum 0.25 long, 0.25 wide, coxa IV separated by 1.79 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: 0.33; TmII: 0.31; TmIII: 0.41. Leg measurements: see Appendix A. Spinnerets (Fig. 19A-D). <b>Natural History.</b> This species builds a three-dimensional spherical web typical of the Mysmenidae (Fig. 20A).
