Abstract

Reptalus salicinus sp. n., previously misinterpreted as R. quinquecostatus, is described and illustrated. Oscillograms of male calling signals with data on host plants and distribution of the new species that is closely related to R. artemisiae (Becker 1865) are provided. A neotype of R. artemisiae is designated. R. salicinus sp. n. and R. artemisiae are similar both in external morphology and male genitalic structure, but differ distinctly by male calling signal patterns and host plants, thus being two different biological species. The distribution of R. salicinus sp. n. covers southern European Russia, Kazakhstan and, apparently, the southern part of Western Europe. R. artemisiae is known so far only from the Lower Volga region and western Kazakhstan.
