First record of Elga leptostyla Ris, 1911 (Odonata, Libellulidae) from Costa Rica

During research in the Tirimbina Biological Reserve, on the Caribbean slope of Costa Rica, we captured adult specimens and reared larvae of the dragonfly Elga leptostyla Ris, 1911, which belongs to the Libellulidae. This species was previously reported only from southern Panama to northern South America. Therefore, this is the first record of the species and genus from Costa Rica, increasing the number of Libellulidae species recorded in the country to 95. This species’ known distribution is northwards.
