Abstract

Records of Dorlodotia Salée, 1920 in Russia and Ukraine include Thysanophyllum vermiculare Degtjarev, 1973 from the Moliniacian (?)-Livian of the Central Urals, Dorlodotia briarti Salée, 1920 and D. fomitschevi Zhizhina, 1978, possibly synonymous with it, both from the Moliniacian of the Donets Basin, Pseudodorlodotia subkakimii Vassilyuk, 1978 from the Warnantian of the same area and Lonsdaleia sokolovi Dobrolyubova, 1958 from the Brigantian of the Moscow Basin. Protolonsdaleia tenuis Zhizhina, 1978 from the Moliniacian of the Donets Basin, Eolithostrotionella grechovkae Degtjarev, 1973 from the upper Livian (?)-lower Warnantian of the South Urals, as well as E. utkae Degtjarev, 1973 and Thysanophyllum druzhininae Degtjarev, 1973 from the upper Moliniacian (?)-Livian of the Central Urals belong with Ceriodotia Denayer (2011). Dorlodotia and Ceriodotia are related genera and most probably belong to the family Axophyllidae Milne Edwards & Haime, 1851. Eolithostrotionella Zhizhina, 1956 is restricted to the Moliniacian of the Donets Basin and probably related to Axoclisia Semenoff-Tian-Chansky, 1974. Eolithostrotionella cystosa Zhizhina, 1960, E. rotai Zhizhina, 1960 and E. lissitzini Zhizhina, 1960 reported from higher intervals of the Donets Lower Carboniferous succession, are morphologically similar to Ceriodotia, but probably belong to a separate genus. Validity of the genera Protolonsdaleia Lissitzin, 1925 and Sublonsdaleia Lissitzin, 1925 should be discussed.
