Ceutorhynchus querceti (Gyllenhal, 1813)

( Figs 6, 22)

Distribution. Holarctic species with the Arctic, boreal and northern subboreal distribution ( Colonnelli, 2004).

Hosts. Mostly on Rorippa palustris throughout most of its Holarctic range ( Dieckmann, 1972), also in several localities in Tuva [West Sayan Mts: 80 km N of Teli Vill.; southern foothills of West Sayan, town of Turan; Central Tuvinian depression – Chadan River flood plain, Lake Chagytai, Seserlig (25 km NW of Kyzyl), Kok-Tey east of Kyzyl; Shurmakskii Pass on Eastern Tannu-Ola Mt. Range; Sagly and Erzin villages in southern Tuva; Yrban Vill. on East Tuva Plateau; my collections of 1979 and 1980], but beetles were found in southern Tuva in numbers on Draba nemorosa or D. sibirica and did not occur on R. palustris closer to the creek ( Korotyaev, 1992), maybe to escape flooding.
