Etymology. The specific epithet refers to its similarity with Hahnia saccata Zhang, Li & Zheng, 2011 ; adjective.

Diagnosis. The new species is similar to H. saccata in having a similar palpal patellar apophysis, tegular setae, embolus, median apophysis and cymbial furrow of male palp and the same location of copulatory openings of epigyne, but can be distinguished from this species by the relatively thin and long RTA and the longer row of tegular setae approaching the prolateral margin of bulb in ventral view of male palp ( Figs 10E–G , 12A–C ); epigyne with a small oval atrium, copulatory opening hidden inside atrium; copulatory ducts coiled around subspermathecae, the latter smaller than spermathecae.

Description. Male (holotype). Total length 2.71. Prosoma 1.43 long, 1.08 wide; Opisthosoma 1.44 long, 0.99 wide. Eye sizes and interdistances: AME 0.05, ALE 0.09, PME 0.07, PLE 0.09; AME–AME 0.03, AME–ALE 0.03, PME–PME 0.07, PME–PLE 0.07, ALE–PLE 0.02. MOA 0.19 long, front width 0.13, back width 0.21. Clypeus height 0.14. Chelicerae with distinct stridulatory files ( Figs 13C–D ), 3 promarginal, 6 retromarginal teeth. Leg measurements: I 4.22 (1.24, 1.44, 0.90, 0.63); II 3.99 (1.18, 1.33, 0.87, 0.62); III 3.64 (1.03, 1.14, 0.88, 0.59); IV 4.62 (1.29, 1.49, 1.12, 0.72). Leg formula: 4123. Spiracle long and transverse, the distance of spiracle to epigastric furrow as long as to spinnerets ( Fig. 10B ).

Male palpal patella with a hooked apophysis originating retro-laterally. RTA sharply curved. Tegulum with a series of setae marginally near prolateral and submarginally near proximal margin. Embolus originating retrolateroproximally, tip of embolus lying near the membranous median apophysis. Cymbial furrow deep and shorter than half cymbium ( Figs 10E–G , 12A–C ).

Female (paratypes). Total length 2.76–3.22. Prosoma 1.38–1.50 long, 1.05–1.13 wide; Opisthosoma 1.52–1.66 long, 1.12–1.24 wide. One of them total length 3.22. Prosoma 1.50 long, 1.13 wide; Opisthosoma 1.66 long, 1.24 wide. Eye sizes and interdistances: AME 0.05, ALE 0.09, PME 0.07, PLE 0.08; AME–AME 0.04, AME–ALE 0.02, PME–PME 0.07, PME–PLE 0.05, ALE–PLE 0.03; MOA 0.15 long, front width 0.19, back width 0.22. Clypeus height 0.13. Leg measurements: I 3.82 (1.12, 1.30, 0.80, 0.59); II 3.55 (1.05, 1.17, 0.77, 0.56); III 3.32 (0.94, 1.05, 0.78, 0.54); IV 4.30 (1.22, 1.38, 1.03, 0.67). Leg formula: 4123.

Epigyne with a small and transversal oval atrium near epigastric furrow. Two copulatory openings hidden inside the anterio-lateral margin of atrium. Copulatory ducts firstly extending anterio-laterally, then coiled mesally and bifurcated, one branch short, connected with the subspermatheca, the other branch long, connected with the ball-like, posterior-laterally located and widely separated spermatheca. Fertilization ducts short, originating from posterior spermathecae, pointing laterally ( Figs 11C–D , 12D–E ). Behind epigastric furrow a pair of oblique curved hoods ( Figs 11B–C , 12D ).

Distribution. Known only from the type locality in Yunnan, China ( Fig. 16 ).
