Type material. CHINA: Yunnan Province: Holotype male, Baoshan City, Longyang District, Nankang , Gaoligong Mountains Nature Park , 24°49'40.195" N, 98°46'9.228" E, elev. 2203m, 8 November 2016, Z.W. Dong leg. ( SWUC).

Etymology. This new species is dedicated to Mr. Zhi-Wei Dong, collector of the new species and good friend of the first author.

Diagnosis. Male of the new species can be distinguished from other Hahnia species by the relatively short RTA, the short and protuberant LTA retrolateralo-proximally and the presence of some strong tibial setae ( Figs 3E– G , 4A–C ).

Description. Male (holotype). Total length 2.20. Prosoma 1.07 long, 0.79 wide; Opisthosoma 1.26 long, 0.93 wide. Eye sizes and interdistances: AME 0.06, ALE 0.08, PME 0.05, PLE 0.08; AME–AME 0.03, AME–ALE 0.02, PME–PME 0.08, PME–PLE 0.06, ALE–PLE 0.02. MOA 0.17 long, front width 0.15, back width 0.20. Clypeus height 0.14. Chelicerae with stridulatory files laterally ( Figs 3C–D ), 2 promarginal, 6 retromarginal teeth.

Leg measurements: I 4.56 (1.30, 1.63, 1.06, 0.57); II 3.50 (0.99, 1.18, 0.82, 0.51); III 2.90 (0.88, 0.92, 0.69, 0.41); IV 3.35 (0.99, 1.09, 0.79, 0.48). Leg formula: 1243. Spiracle long and transverse, distance of spiracle to epigastric furrow 2.4 times as long as to spinnerets ( Fig. 3B ).

Male palpal patella with a hook-like apophysis retrolatero-proximally, the patellar apophysis with a notch apically. Tibia covered with cluster of black setae at dorsal and retrolateral surface, with moderately short RTA extending dorsally and LTA proximally, tip of LTA covered with several black setae. Embolus originating retrolatero-proximally, tip of embolus lying near base of membranous median apophysis. Cymbial furrow deep and nearly as long as half of cymbium ( Figs 3E–G , 4A–C ).

Female unknown.

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