Griswold, CGY29 (CASENT 9019872, HNU), 1 ♁, 2 &amp;female;. <b>Etymology.</b> Formed from the Chinese word for groove (g&amp;omacr;u dào), referring to the wide tuberculate groove on the male cymbium. <b>Diagnosis.</b> Male distinguished by the cymbial groove studded with tubercles (Fig. 29A). Female distinguished from most Chinese <i>Mysmena</i> by the lack of scape or other external structures to the epigynum (Fig. 29F); distinguished from <i>M. haban</i> and <i>M. shibali</i> by the presence of a spermatheca/copulatory duct complex (Fig. 21G; spermathecae simple and round to oval, distinct from lightly sclerotized copulatory ducts in <i>M. haban</i> and <i>M. shibali</i>; Figs 21I, 31B). <b>Description.</b> Carapace orange, sulci absent. Sternum dusky orange. Legs orange. Femoral spots on legs I and II. Abdomen gray with four white spots on posterior; posterior tubercle absent (Fig. 27 A-E). Male palp: Embolus spiral, follows tegular groove for most of length, engages with cymbium distally (Fig. 28, 29C). Cymbium with wide groove studded with tubercles (Figs 28A, 29A). Cymbial base with lobes, no apophyses (Fig. 29B). Tip of cymbium divided into several thin terminal apophyses (Fig. 28B). Vulva: Epigynum weakly sclerotized, without scape or any other obvious external structure (Fig. 29F); internal structures visible through cuticle (Fig. 21F). Copulatory ducts with multiple turns, atria clearly visible; region between atria with wrinkled texture (Fig. 21G). Sclerotized portion of spermatheca/copulatory duct complexes separated by more than their width. Male (CASENT 9016245): Total length 0.71, carapace 0.40 long, 0.39 wide, clypeus 0.16, sternum 0.26 long, 0.26 wide, coxa IV separated by 1.50 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 macrosetae gradually curved. Metatarsal trichobothria: TmI: 0.25; TmII: 0.36; TmIII: 0.35. Leg measurements: see Appendix A. Epiandrous gland spigots in two widely spaced clusters of two spigots each. Posterior lateral spinnerets with flagelliform and aggregate gland spigots reduced to nubbins (Fig. 29E). Female (CASENT 9016245): Total length 0.98, carapace 0.46 long, 0.43 wide, clypeus 0.13, sternum 0.29 long, 0.29 wide, coxa IV separated by 1.80 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: 0.28; TmIII: 0.35.
