Etymology. Named for the type locality. The epithet is a noun in apposition.

Diagnosis. Distinguished from most other Chinese Mysmena species by the lack of a well defined scape (Fig. 31A); distinguished from M. goudao by having the spermathecae simple and round (Fig. 31B) rather than part of a complex with the copulatory ducts (Fig. 21G); distinguished from M. haban by the separation of the spermathecae (nearly three times their diameter in M. shibali , about 1.5 times their diameter in M. haban ; Fig. 21I), the path of the fertilization ducts (sinuous in M. shibali , J-shaped in M. haban ), and the presence of a posterior abdominal tubercle in M. shibali (absent in M. haban ).

Description. Carapace brown with lighter patches around thoracic margin. Sternum yellow with dark spots. Legs yellow, distal part of tibiae darker. Femoral spots on legs I and II. Abdomen dark brown with numerous tan spots, with four dorsal white spots, four to six lateral white spots, and two longitudinal white lines laterally running to posterior tubercle, region between white stripes tan with dark brown chevrons ( Fig. 27 View Figure 27 F-H).

Vulva: Epigynum a soft triangular process pointing posteriorly (Fig. 31A). Oval spermathecae separated by nearly 3 times their diameter (Fig. 31B). Copulatory ducts weakly sclerotized throughout. Fertilization ducts relatively well sclerotized, arise from mesal part of spermathecae, follow sinuous path running mesally and posteriorly (Fig. 31B).

Female (CASENT 9019885): Total length 0.94, carapace 0.35 long, 0.35 wide, clypeus 0.04, sternum 0.26 long, 0.24 wide, coxa IV separated by 1.67 times their width. Macrosetae: Leg I: patella d1, tibia d2; Leg II: patella d1, tibia d2; Leg III: patella d1, tibia d1; Leg IV: patella d1, tibia d1. Metatarsal trichobothria: TmI: 0.36; TmII: 0.26; TmIII: 0.39. Leg measurements: see Appendix A.
