NOTE. The nominotypical subspecies is distributed from Fennoscandia, Northwest Russia, Khanty-Mansi Autonomous Okrug, Tyumen Oblast to Russian Far East [ Oosterbroek, 2021; Oosterbroek, Reusch, 2008; Savchenko, 1989; Stolbov et al., 2018]. Pilipenko et al. [2016] believed that all three taxa in species Ch. crassipes do not deserve subspecies status, but at the same time, the eastern population of Ch. crassipes differs from the western one in an increased and unstable number of antenna segments. The specimens of Ch. crassipes collected in the Sikhote-Alin Biosphere Reserve in 2016–2019 confirm the occurrence of this rare and interesting species of snow cranefly in Primorsky Krai. In all collected specimens of Ch. crassipes (both sexes), antenna with 9 segments. In all published data, the number of antennal segments in Ch. crassipes ranges from 5 to 7.
