The new species is similar to T. assamensis Manickavasagam and Ayyamperumal, 2018, but can be separated from T. assamensis by a combination of the following characters: scape about 5.5× as long as broad (in T. yunnanensis, scape about 5.8× as long as broad); F3−F5 longer than broad (in T. yunnanensis F5 wider than long); mid femora and tibiae except apical 1/5 dark brown (in T. yunnanensis only base of tibiae dark brown).</p></div>	https://treatment.plazi.org/id/955D853F890CAE13FF43B702F948FEEE	Public Domain	No known copyright restrictions apply.
