Exceptionally well-preserved dragonflies (Insecta: Odonata) in Mexican amber

Zheng, D., Nel, A., Jarzembowski, E.A., Chang, S.-C., Zhang, H. & Wang, B., May 2018. Exceptionally well-preserved dragonflies (Insecta: Odonata) in Mexican amber. Alcheringa xxx, xxx–xxx.

Dragonflies (odonatans) are comparatively rare as amber inclusions, and most are not well preserved on account of their size. Here, we report a single piece of Mexican amber with one complete dragonfly and two damselflies. The dragonfly is attributed to the extant gomphid Erpetogomphus Selys Longchamps, and the damselflies belong to the extant coenagrionid Argia Rambur. Both genera are nowadays distributed widely in Mexico. The new discovery dates the origins of these two genera to the Miocene at least.
