MATERIAL EXAMINED. Uzbekistan: Tashkent Province: near Bashkyzylsay River , 1200–1400 MSL, 16. VI.1980, 1♀ (D. Kasparyan) [ ZISP]. Unreadable label, 1860s, 1♂ (F. Sichel) [ ZISP] .

DISTRIBUTION. (?) Russia. Algeria Austria, Belgium, Bulgaria, Croatia, Czech Republic, France, Germany, Great Britain, Hungary, Italy, Morocco, Netherlands, Portugal, Romania, Slovakia, Slovenia, Spain, Switzerland, Turkey, Ukraine, * Uzbekistan.

HOST PLANT. Pyrus spp. , Crataegus spp. , Malus spp. ( Rosaceae ).

NOTE. The species has been repeatedly noted in the literature for the territory of Russia ( Zhelochovtsev, 1988). Also Gussakovskij (1935) indicated the species for the environs of Maykop, but without detailed label data. In the ZMMU collection we found a specimen of Janus compressus collected near Maykop, identified by D. Dovnar-Zapolskij, which was re-identified as Janus luteipes . We were unable to find any specimens collected in Russia in all studied museums and collections. Besides, in the catalog of the European sawflies ( Taeger et al., 2006), this species was not noted for Russia. However, we believe that this species is rare, but present in the fauna of Russia.
