Hemp sawfly found in European Russia (Hymenoptera: Tenthredinidae, Nematinae, Cladiini)

Abstract

The hemp sawfly Trichiocampus cannabis Xiao & Huang, 1986 was known until now only in the East Palaearctic. One female was captured recently in the Uljanovsk Region, European Russia. This is the first record from the West Palaearctic. The species is compared with the type species of Trichiocampus Hartig, T. grandis (Serville). The hemp sawfly differs from all known species of Cladiini by having slender, simple claws. The food plant Cannabis sativa L., a herb of the family Cannabaceae, is unique in Cladiini.
