Phylogenetic analysis of the Cenozoic family Sieblosiidae (Insecta: Odonata), with description of new taxa from Russia, Italy and France

Abstract We describe the following Sieblosiidae: an unamed “gen. and sp. A” from the Miocene of Italy, Miostenolestes zherikhini nov. gen., nov. sp., Paraoligolestes stavropolensis nov. sp., Stenolestes fasciata nov. sp. (all from the Miocene of North Caucasus), Stenolestes (?) adygeianensis nov. sp. (Oligocene of North Caucasus), and Stenolestes cerestensis nov. sp. (Oligocene of France). The genus Sieblosia Handlirsch, 1906 is restored. A new phylogenetic analysis of the Sieblosiidae is proposed. The two taxa “gen. and sp. A” and Oligolestes fall in most inclusive positions in the same clade with the Sieblosiidae. Within the Sieblosiidae sensu stricto, the two clades ( Paraoligolestes + ( Parastenolestes + Stenolestes )) and ( Parastenolestes + Stenolestes ) are the best supported. The family Sieblosiidae seems to be restricted to the Oligocene–Miocene of Europe.
