NOTES. The two vicarious species, West Palaearctic I. serpentata and East Palaearctic I.

dohlmanni, are almost identical on appearance and definitely distinguishable only by the genitalic structure, that results to numerous misidentification of the last species as first one

(Viidalepp, 1987; Burnasheva, Beljaev, 2011). All studied specimens of " I. serpentata " from

Irkutskaya oblast, deposited in the collections of Zoological Institute (materials by I. Ko-

zhanchikov – 3♂♂, and S. Rodionov – 2♂♂), Biological Faculty of Irkutsk State University

(11♂♂) and Siberian Institute of Plant Physiology and Biochemistry (8♂♂) actually belong to I. dohlmanni . No samples of I. serpentata were also detected in the author's materials from

Baikal region (11♂♂, 1♀). Thus, the eastern range limit of I. serpentata is presumably laid to the west of the Baikal region .
