Abstract

For the first time, information is provided about the presence of Najas tenuissima in the northeast of Tyva (Todzha District, Azas Lake), which significantly expands the knowledge on the species distribution in Russia. Najas tenuissima is a rare species listed in the “Red Data Book of the Russian Federation”. In Russia, its range is disjunctive; a few localities are known in the European part, the south of Central Siberia (Eastern Sayan: Tiberkul and Spasskoye Lakes) and in the Far East (Amur Region and Primorye Territory).
