This species is named in honor of Mr. Ge Hu and Mr. Tin-Lok Koo, two renowned actors, as an appreciation for their contribution to elementary education and environmental preservation in the mountainous areas of western China. Following Article 31.1.2 of the International Code of Zoological Nomenclature (4th edition), the specific name is treated as a noun in the genitive plural case. Type specimens will be deposited in the Museum of Biology, Peking University. Holotype ♂, Hailuogou Glacier Forest Park, 15 March 2019, collected by Jingjing Guo. Paratypes, 4 ♂, 5 ♀, same data as holotype. The new species is somewhat similar to Nemoura concava Li &Yang, 2008, but it may be separated from the latter by the cercus with two distal spines, and the epiproct with a bifurcate apex. In N. concava, the cercus has only one distal spine, and the epiproct has a triangular indentation apically.
