New fossil odonata from the European cenozoic (Insecta: Odonata: Thaumatoneuridae, Aeshnidae, ?Idionychidae, Libellulidae)

A new genus and species of the fossil subfamily Thaumatoneuridae: Dysagrioninae Primorilestes violetae is described from the Early Oligocene of the Far East of Russia. The aeshnid Aeschnophlebia andreasi sp. n. is described from the Late Eocene/Early Oligocene of the UK. Oligoaeschna (?) anglica COCKERELL & ANDREWS, 1916 is redescribed on the basis of new, more complete material from the same strata. The hindwing structures of Oligaeschna jungi PITON & THEOBALD, 1939 are described on the basis of a complete wing from the Oligocene of France, Aeshna stavropolensis sp. n. (Aeshnidae), Mioidionyx stavropolensis gen. n. sp. n. (?Idionychidae), two wings attributed to Sympetrum aff. elongatum GENTILINI, 1989, and two unnamed Pantalinae (Libellulidae) are described from the Middle Miocene of Stavropol (North Caucasus, Russia). Libellula ukrainensis sp. n. is described from the Late Miocene of Crimea (Ukraine). The libellulid Jeanlegrandia oligocenica gen. n. sp. n. is described from the Late Oligocene of France. These new discoveries confirm the high diversity of the Cenozoic odonatofauna of the Palaearctic Region.
