Description. Male ( holotype ). Total length 2.70. Prosoma 1.28 long, 0.93 wide; Opisthosoma 1.47 long, 1.03 wide. Eye sizes and interdistances: AME 0.05, ALE 0.09, PME 0.08, PLE 0.09; AME–AME 0.03, AME–ALE 0.02, PME–PME 0.05, PME–PLE 0.05, ALE–PLE 0.02. MOA 0.19 long, front width 0.12, back width 0.23. Clypeus height 0.11. Chelicerae with distinct stridulatory files laterally ( Figs 16C–D ), 3 promarginal, 7 retromarginal teeth. Leg measurements: I 3.58 (1.04, 1.18, 0.77, 0.59); II 3.36 (0.96, 1.09, 0.73, 0.58); III 3.04 (0.88, 0.95, 0.71, 0.51); IV 3.84 (1.09, 1.22, 0.92, 0.61). Leg formula: 4123. Spiracle long and transverse, the distance of spiracle to epigastric furrow as long as to spinnerets ( Fig. 13B ). Embolus originating retro-basally, tip of embolus lying near base of membranous median apophysis. Cymbial furrow deep and nearly as long as half of cymbium ( Figs 13E–G , 15A–C). Female ( paratypes ). Total length 3.00–3.26. Prosoma 1.38–1.50 long, 1.00–1.10 wide; Opisthosoma 1.67–1.82 long, 1.19–1.30 wide. Eye sizes and interdistances: AME 0.05, ALE 0.09, PME 0.08, PLE 0.09; AME–AME 0.04, AME–ALE 0.03, PME–PME 0.08, PME–PLE 0.05, ALE–PLE 0.01; MOA 0.19 long, front width 0.13, back width 0.27. Clypeus height 0.13. Leg measurements: I 3.81 (1.12, 1.31, 0.77, 0.60); II 3.53 (1.04, 1.17, 0.74, 0.58); III 3.21 (0.94, 1.01, 0.73, 0.54); IV 4.15 (1.20, 1.37, 0.93, 0.66). Other characters as in males. Epigyne with a pair of small copulatory openings centrally. Copulatory ducts bifurcated near copulatory openings, short branch connected with subspermathecae and with tuberculate expansion near base (green arrows and red arrows indicate in Figs 14D , 15E), long branch roundly coiled, finally connected with spermathecae, the latter sub-globular and located posterior-laterally. Subspermathecae oval, smaller than spermathecae and next to globular spermathecae. Fertilization ducts short, originating from posterior of spermathecae and pointing laterally ( Figs 14B–D , 15D–E).
