Description

Janus compressus (Fabricius, 1793)

Figs 3A, D–E

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.
