Other material studied: Russia , Volgograd oblast , Olhovka village 20 km S, 23.IX.2002 ( 1♂ ), K. Nupponen leg. ( KN ) . Distribution. Russia (S Ural, Lower Volga), S Siberia. Remarks. S. lineolella was described from S Ural. However, because it was considered a problematic species according to the criteria of the catalogue of European Lepidoptera ( Karsholt et al . 1996 ) it was not mentioned in that work. Externally S. lineolella can be separated from the closely related S. mongolica Povolný, 1975 by the presence of a characteristic dark, distinct longitudinal basal streak in the forewing, which is missing in mongolica , and by the smaller size of the adult ( 11–15 mm ; in mongolica 17–19 mm ). There are also differences in the male genitalia: in S. lineolella the valva is more slender and gradually curved from base to tip, and the aedeagus is distinctly shorter; in S. mongolica the valva is medially slightly broader and more strongly bent than in the other parts, and a narrow distal part of the aedeagus is longer. Recently described S. radicalis Falkovitsh & Bidzilya, 2003 also has a longitudinal basal streak in the forewing, but the adult is larger ( 16–19 mm ) and paler, and in the male genitalia the valva and the aedeagus are more slender than those of S. lineolella (Bidzilya pers. comm.; Falkovitsh & Bidzilya 2003 ). S. radicalis has been reared from Artemisia turanica .
