Abstract

Seven species from 5 groups of the weevil genus Ceutorhynchus Germ, have been found on a spring and early summer ruderal ephemeral crucifer, woodland draba (Draba nemorosa L.), in the southern regions of Eastern Siberia. Three species (C kipchak Kor, C. ? unguicularis Thorns., and C. klementzorum Kor.) have been found only on this species (the latter two also on the closely related Draba sibirica (Pall.) Thell.). Ceutorhynchu cochleariae Gyll. occurs on the woodland draba at the eastern, and C. dauricus Kor, at the western border of their ranges and both have other crucifers as main hosts; the Holarctic C. querceti Gyll. feeds on D. nemorosa (or on D. sibirica) in the areas where its main host does not occur, and the Dauro-Mongolian C. seniculus C. Bris. develops on many other crucifers besides the draba. Draba nemorosa is the first known host of the Dauro-Mongolian C. klementzorum.

Acknowledgments

I greatly appreciate the invitation to the joint investigation of the relict communities with Ulmus japonica in southwestern Transbaikalia by E.V. Sofronova (V.B. Sochava Institute of Geography, Siberian Branch of the Russian Academy of Sciences, Irkutsk) and friendly help of all the members of the expeditions of 2018 and 2019—O.A. Anenkohov (Ulan-Ude), V.V. Chepinoga, A.A. Lysov, and A.P. Sofronov (V.B. Sochava Institute of Geography, Siberian Branch of the Russian Academy of Sciences, Irkutsk). Invaluable was the help of O.A. Anenkohov, V.V. Chepinoga, and A.R Sofronov in identification of plants and other advice on the botany, ecology, and geography of the region. I cordially thank VI. Dorofeyev (VL. Komarov Botanical Institute of the Russian Academy of Sciences, St. Petersburg) for identification of my herbarium specimens of crucifers from West Sayan Mts.
