Type material.
Holotype ♀: China: Yunnan Province: Tengchong County, Mangbang Village,

Etymology.
The specific name refers to the type locality; adjective.
Diagnosis.
The female is similar to that of
Sinocoelotes hehuaensis
sp. n., but can be distinguished from it by longer epigynal teeth (twice as long as in
Sinocoelotes hehuaensis
sp. n.), the broader copulatory ducts, which the posterior part separated from each other further, the slender, laterally and ventrally located spermathecal heads (dorsally situated in
Sinocoelotes hehuaensis
sp. n.) (cf. Figs 14
A-B
and 8
A-B
).

Description.
Female. Total length 10.12. Carapace 4.94 long, 3.66 wide. Abdomen 5.18 long, 3.10 wide. Eye sizes and interdistances: AME 0.21, ALE 0.29, PME 0.20, PLE 0.24; AME-AME 0.11, AME-ALE 0.05, PME-PME 0.16, PME-PLE 0.28.
