Pictetiella asiatica Zwick & Levanidova, 1971: 853 ; Zwick, 1973: 238; Zhiltzova & Zapekina-Dulkeit, 1986: 183; Zhiltzova, 1995: 7; Teslenko, 2009: 698; Teslenko & Zhiltzova, 2009: 32; Judson & Nelson, 2012: 44; Murányi, Hwang, Jeon & Seo, 2016: 113.

Material examined. One male, China: Jilin Province, Changbaishan National Natural Reserve, Pond of the Visitor Center ( Fig. 15 ), 42.07111 N, 128.06358 E, 1700 m, June 29, 2011, J. Morse, J. Murphy, Z. Diao (donated by Shuang Qiu in 2019, ICJUST). One male, Jilin Province, Antu County, Erdaobaihe Town, Tributary of Jianshui River ( Fig. 15 ), 42.38248 N, 128. 13431 E, 757 m, June 28, 2011, J. Morse, J. Murphy, Yun-Jun Yan, Zhi-Cai Xie (donated by Shuang Qiu in 2019, ICJUST).

Remarks. Body ( Figs. 18 , 19 ) length ca. 15 mm (excluding antennae and cerci). This species is originally described from Russia, and is now only known from Mongolia, North Korea, and Russia ( DeWalt et al. 2019). Morphology of the specimens studied herein is almost identical with that of Murányi et al. (2016), who redescribed the North Korean specimens also from the Changbai (Baekdu) ranges. Discovery of Pictetiella from northeastern China fills the gap of the generic distribution between Mongolia and North Korea.
