DNA barcodes of 75 samples from 10 species were obtained, four of which were previously described from Kamchatka watercourses. Comparative analysis of the new sequences and data from the BOLD system made it possible to expand the ranges for Acentrella diptera Kluge et Novikova, 2011, Baetis pseudothermicus Kluge, 1983, Cinygmula malaisei Ulmer, 1927, Ephemerella aurivillii Bengtsson, 1908, and E. mucronata Bengtsson, 1908. Sequences XJDQD534-18 - XJDQD542-18 from China should be transferred from the genus Baetiella Ueno 1931 to the species Baetis pseudothermicus. Despite the high K2P distances for Ephemerella mucronata and E. aurivillii, we do not consider to divide them into several species and propose to increase the threshold of intraspecific differences by 6.47% or more for the genus Ephemerella Walsh of the family Ephemerellidae.
