Three new Macropsis species from Eastern Siberia (Transbaikal region) and the Russian Far East are described. Macropsis daurica Tishetchkin, sp.n. feeding on Salix triandra nipponica and M. leporina Tishetchkin, sp.n. feeding on willows from the section Vimen (S. schwerinii, S. udensis) belong to the group of uniformely-green cospecies. M. multa Tishetshkin, sp.n. feeding on S. brachypoda has both green and brown varieties, the former being more abundant; Uniformely-green M. ochotonaria Tish., 1994 appears to have also pale-yellow form with two longitudinal black stripes; M. arvicolaria Tish., 1996 described basing on the yellow form with black stripes has also a uniformely-green variety. In all cases the temporal structure of acoustic signals in forms of different colour is identical: Oscillograms of calling signals of males of the studied species are given.
