New Cenozoic dragonflies from the Most Basin and Stredohori Complex volcanic area (Czech Republic, Germany)
Abstrakt
Discovery of new dragonflies from Oligocene and Miocene deposits of the Most Basin and Ceske Stredohori Complex volcanic area in northern Bohemia and Saxony (Germany) is reported. Aeshna zlatkokvaceki sp. nov. is the first described dragonfly from early Miocene salmon-pink baked clays of Zelenky near Duchcov.
Its fore wing venation pattern seems to be closely related to that of Aeshna turoliana Riou and Nel, 1995, known from late Miocene of La Montagne d'Andance in Ardeche, France, and Aeshna solida Scudder, 1890, known from late Eocene of Florissant in Colorado, USA. A new occurrence of a libellulid dragonfly ? Onychothemis rihai in the Libkovice Member of Most Basin confirms the links to the Cypris Formation in Sokolov and Cheb basins reflecting similar habitats as was already shown on the basis of reconstructed palaeovegetation and shared thermophilous and accessory floristic elements.
Other fragmentary fossil material from different localities are discussed.
