The larvae of Cinygmula malaisei (Ulmer, 1927) and Cinygmula unicolorata Tshernova, 1979 from the Russian Far East are described and illustrated. The larva of Cinygmula unicolorata is similar to those of Cinygmula putoranica Kluge, 1980 and Cinygmula uyka Gorovaya et Tiunova, 2013 but differs from the larva of C. uyka in the absence of gill filaments and from that of C. unicolorata in the shape of the first gill (tergalia). The upper outer margin of the first gill is rounded in the larva of C. unicolorata and almost straight in C. putoranica; the gills of C. unicolorata are matte and the trachea is poorly expressed, in contrast to the distinctly brown trachea of C. putoranica. The larvae of Cinygmula malaisei are similar to those of C. irina and C. autumnalis but differ from the latter in the presence of gill filaments. The larva of C. malaise differs from that of C. irina in the rounded outer margin of the first gill, the shape of gills VI and VII, and in the size of the leg segments.
