ringtails
Erpetogomphus is a genus of dragonflies in the family Gomphidae, commonly known as ringtails. The genus comprises approximately 25 extant species distributed primarily in the Americas, plus one fossil species from Early Miocene Mexican amber. Most species exhibit predominantly green coloration, and males possess a moderately clubbed abdomen tip. The genus was taxonomically revised by Rosser Garrison in 1994.
