INTRODUCTION Order LEPIDOPTERA

The bucculatricid fauna of the Primor- Family BUCCULATRICIDAE sky Territory of Russia incorporates 25 Bucculatrix Zeller, 1839 species of the genus Bucculatrix (Barysh- Bucculatrix lovtsovae nikova, 2008a), which were predominantly sp. nov. described by the author of this communi- (Figs 1, 2) cation.
