( Figs 3, 13)

Distribution. South of East Siberia, Northeastern Yakutia , Magadan Prov. ( Korotyaev, 1980; as C. changaicus Schultze, 1898 ), Chukchi Autonomous Area ( Berman et al., 2002), Mongolia [ Schultze, 1898 (as C. changaicus ); Voss (1967; as C. gobiensis ), Korotyaev (1980; as C. changaicus )], Northern China ( Alonso-Zarazaga et al., 2017).

Hosts. Several species of Brassicaceae [often Erysimum flavum and E. cheiranthoides , occasionally Smelowskia alba ] in Tuva; Alyssum sp. in Chukotka ( Berman et al., 2002). During two short expeditions in Buryatia this species was never found on Erysimum sp. in the Selenga flood plain or on Smelowskia alba and Alyssum lenense in Barguzin Valley and was common only on Draba nemorosa in two flood-plain ruderal localities at the southern boundary of the taiga zone on the Khilok River in the absence of other crucifers around and in the forest-steppe zone at the Chikoy River, also with a poor flora of Brassicaceae ( Korotyaev, 2019) .
