The mayfly sister group family Misthodotidae Tillyard, 1932 includes two genera: Misthodotes Sellards, 1909 and Triassodotes Sinitshenkova & Papier, 2005. Misthodotes species have so far been known only from the Permian, six Early Permian species have been described from North America (Carpenter, 1933, 1979; Tillyard, 1932, 1936), one from Germany (Kinzelbach & Lutz, 1984) and two from the Perm region of Russia (Tshernova, 1965). Only three species are known from the Upper Permian deposits: two from the famous Isady locality in the Vologda Region of Russia (Sinitshenkova, 2013; Sinitshenkova & Vassilenko, 2012) and one from the Urals (Novokshonov et al., 2002). The only Triassodotes species was found in the Middle Triassic Grès à Voltzia deposits in France (Sinitshenkova et al., 2005).
