Etymology
The word Adversaeschna is a combination of two Latin words: adversus, meaning opposite in physical position; and aeschna, derived from the genus Aeshna named by Danish entomologist Johan Fabricius in 1775. Adversaeschna brevistyla was described by Tony Watson in 1992 as being taxonomically isolated from other dragonflies in the genus Aeshna.
