All adult collections are confined to the neighborhood of lotic waters and carried out in the second half of July (Fig. 7). Together with the new species in the studied water bodies Trichotanypus christmasus Makarchenko, 1983</p> <p>(Podonominae), Diamesa cinerella Meigen, 1835 (Diamesinae), Constempellina brevicosta (Edwards, 1937) (Chironominae), and 22 species of Orthocladiinae were collected, among which the most interesting are Hydrobaenus laticaudus Saether,</p> <p>1976, H. pilipodex Saether, 1976, Krenosmittia halvorseni (Cranston et Saether,</p> <p>1986), Parasmittia carinata Strenzke, 1950, and Rheocricotopus (Rheocricotopus)</p> <p>gavriloae Krasheninnikov, 2015.</p> <p>ETYMOLOGY. The species is named in honor of the Russian biologist Alexey</p> <p>A. Byalynitsky-Birulya (1864–1937), who participated in the Russian polar expedition in 1900–1902 led by Eduard von Toll to study the New Siberian Islands and search for the legendary Sannikov Land.</p> <p>REFERENCES</p> <p>Ashe, P. &amp; O’Connor, J.P. 2012.
