This species includes two subspecies: Stenus notaculipennis emeiensis Zheng, 1992 and Stenus notaculipennis notaculipennis Puthz, 1991. The former can be distinguished from the latter by the following characteristics: Median lobe of aedeagus (Figs. 11 A & 12 A) with a larger and more truncate apical sclerotized area. Most specimens found from Sichuan (Emei Shan) are obviously to the former. However, we also found one specimens from Sichuan (Emei Shan, 1 male, 28. VIII. 2005, Ye-Jun Zhang leg.) with its aedeagus (Figs. 13 & 14) somehow near to the subspecies notaculipennis Puthz, 1991. This problem is still open for further study until we have more materials from the type localities of both.	en	Lv, Wei-Xiang, Zhao, Cai-Yun, Zhou, Hong-Zhang (2018): Taxonomy of Stenus tenuimargo group (Coleoptera, Staphylinidae, Steninae) with descriptions of two new species from China.
