On dragonfly nymphs (Insecta: Odonata: Anisoptera) from the caldera of the Cerro Azul volcano, Isla Isabela (Galapagos Archipelago, Ecuador)

摘要

We describe nymphs of the spot-winged glider, Pantala hymenaea, encountered during an expedition to the caldera of the Cerro Azul volcano on Isabela island in February 2009. This faunistic shortnote provides the first species-level identification of odonates from a caldera lake of an active Galapagos volcano.
