ABSTRACT. Illustrated redescription of adult male as well as the results of DNA barcoding of Thalassosmittia marina (Sounders, 1928) in comparison with the British Columbia population and known species of the genus Thalassosmittia Strenzke et Remmert, 1957 from the coast of Kamchatka in the Russian Far East are provided. DNA barcodes obtained for Orthocladius sp. (locus COI-5P), belonging to BIN BOLD:ACP8936, as well as the sequence of Thalassosmittia sp. 1 (GenBank number HQ441011, BOLD ID number GBDP42937-19, locus COI-3P) are conspecific with Thalassosmittia marina.
KEY WORDS: Diptera, Chironomidae, Thalassosmittia marina, redescription, DNA barcoding, Kamchatka, Russian Far East.
