Helocordulia Needham, 1901

Helocordulia is a genus of dragonfly in the family Corduliidae. They are commonly known as sundragons.

These are medium-sized odonates, 38–46 mm (1.5–1.8 in) long, dark brown with orange markings. They are confined to eastern USA and Canada where their habitat is clear streams and lakes with sandy bottoms.[1]

The genus contains only two species:[2]

Helocordulia selysii (Hagen in Selys, 1878) – Selys's sundragon[3]
Helocordulia uhleri (Selys, 1871) – Uhler's sundragon[3]
