A male syntype of Somatochlora exuberata Bartenev, 1910, from Kavykuchi Gazimurskie village, Transbaikalia, Siberia, June 24 (in Julian Calendar, July 7 in Gregorian Calendar) 1909, was discovered in the Milwaukee Public Museum, Wisconsin, U.S.A., as received in exchange from A.N. Bartenev by Richard Anthony Muttkowski. Another male syntype with the same data later was found in the University of Michigan Museum of Zoology, Michigan, U.S.A. The latter specimen is designated as the lectotype of S. exuberata. The description of Somatochlora vera Bartenev, 1914, a name currently considered a junior synonym of S. exuberata, is critically evaluated.
