The first fossil representative of the Nearctic genus Nasiaeschna in France (Odonata: Aeshnidae)

The Miocene Odonata are rather well documented in France, thanks to many discoveries in the ‘Massif Central’ outcrops of Sainte Reine (latest Miocene, Cantal) and Montagne d’Andance (late Miocene, Ardeche) (Nel et al., 1994, 1996, 1997a,b; Riou & Nel, 1995). Among these, the family Aeshnidae is well-represented by the genera Aeshna Fabricius, 1775, Boyeria MacLachlan, 1896, and Aeschnophlebia Selys, 1883. Thus, it is with great surprise that one of us has found a new well-preserved specimen in the outcrop of Montagne d’Andance, representing a new species that we describe herein.
