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.

Locality of Arcynopteryx polaris Klapálek, 1912 and Pictetiella asiatica Zwick & Levanidova, 1971 in Jilin Province of northeastern China. Remarks. Body ( Figs. 16 , 17 ) length ca. 17 mm (excluding antennae and cerci). The male specimen of A. polaris studied herein is macropterous, unlike most other known brachypterous males as stated by Judson & Nelson (2012) . The following characters of the Chinese male specimen are identical with those of Russian and Mongolian specimens depicted by Teslenko & Zhiltzova (2009) and Judson & Nelson (2012) : the color pattern of head and pronotum; the slender and finger-shaped hemitergal lobes; the two sclerotized bands near the median slit between hemitergal lobes; the back-pointed, long and needle-like epiproct. It is worth noting that many historical specimens of A. polaris were misidentifed as A. altaica Zapekina-Dulkeit, 1957 and finally revised by Zhiltzova (1995) . Teslenko (2006) reported A. polaris from the “East-Manchurian Mountains”, however, the accurate locality is not specified and “Manchuria” is not a recognized toponym now. In the recent generic checklist of Chen & Du (2018) and the species catalogue of Yang & Li (2018) , Arcynopteryx was not included.
