Remarks. Chlorophorus obliteratus is a species with a relatively narrow range that is restricted to some parts of East Siberia, Mongolia, and northernmost China (Inner Mongolia) ( Danilevsky 2020).

The taxonomic confusion associated with this species is discussed in the comments to Ch. caragana . In this paper, we accept the validity of both species and refer here to Ch. obliteratus sensu Zong et al. (2012) . There is almost no data on this species in the literature. However, some basic information on Ch. ubsanurensis , which is currently one of the synonyms of Ch. obliteratus , were given by Cherepanov (1990b) and Xu et al. (2007). Although Cherepanov (1990b), who is also the author of the description of this taxon (based on a single female), mentioned that the biology and immature stages were not known, he informed on the similarity of this species to Chlorophorus varius (Müller, 1766) , from which it, however, differs conspicuously in elytral pattern and other characters. The holotype (7 mm in length) was collected in Ubsanur basin, on northern bank of Lake Uvs ( Mongolia). In turn, Xu et al. (2007) informed on the distribution of this species in Uvs Lake Basin in Mongolia (Khoton and Khurgan Lakes). They also stated that Ch. ubsanurensis can be distinguished from other species by its unique black spots on the pronotum.

Salsola laricifolia Litv. ex Drobow (Amaranthaceae) , Eurotia ceratoides (which is now a synonym of Krascheninnikovia ceratoides (L.) Gueldenst. ( Amaranthaceae )), and Caragana spp. were recorded as plant species, on which imagines of Ch. obliteratus were collected.
