( Figs. 11 , 12 , 13 & 14 )

Puthz, 1991: 39 (subgenus Parastenus ; Type locality: Nepal: Ilam District nördl. Mai Pokhari, Tal der Gitang Khola, 1900– 2100 m); Zheng, 1993: 225, 227 (subgenus Parastenus ; key characters; China; Nepal); Herman, 2001a: 2306; Smetana, 2004: 544 (Palaearctic catalog); Puthz 2013a: 1399; Schülke & Smetana, 2015: 832 (Palaearctic catalog). Syn.: Stenus notaculipennis emeiensis Zheng, 1992: 167 (subgenus Parastenus ; subspecies of notaculipennis ; Type locality: China: Sichuan: E-Mei-Shan, 710–1450 m).

Material examined: China: Sichuan: Emei Shan , 3 males, 7 females, 29.VIII. 2 0 0 5, Cai-Yun Zhao leg. ( IZ- CAS). Emei Shan, 2 males, 4 females, 700–800 m, 28.VIII. 2005, Xiao-Yan Zhao leg. (IZ-CAS). Emei Shan, 1 male, 29.VIII.2005, Yong-Jie Chen leg. (IZ-CAS). Emei Shan, 1 male, 28.VIII.2005, Ye-Jun Zhang leg. (IZ-CAS).

Remarks: This species can be distinguished from S. zhangyejunianus Lv et Zhou , sp. nov by the following characteristics: body size smaller, larger elytra spot, punctures on pronotum barely confluent and well reticulated. 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. 11A & 12A ) 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.

Distribution. China (Sichuan, Yunnan, Hainan), India, Nepal.
