Austroagrion exclamationis is a species of damselfly in the family Coenagrionidae, commonly known as a northern billabongfly. It is a small damselfly; the male is blue and black. It has been recorded from New Guinea and northern Australia, where it inhabits streams and still water.
Etymology The genus name Austroagrion combines the prefix austro- (from Latin auster, meaning "south wind", hence "southern") with Agrion, a genus name derived from Greek ἄγριος (agrios, "wild"). Austroagrion thus refers to a southern representative of that group.
The species name exclamationis is derived from the Latin exclamatio ("exclamation"), referring to the marking on segment 3 of its abdomen.
