Ovion

The Ovions are a race of insectoid sapients who were ultimately conquered by the Cylon Empire. They are enslaved and forced into an alliance alongside other races such as the Delphians and the Hasaries known as the Cylon Alliance. As slaves, they have been transported to the planet Carillon to take part in mining operations held there. They are presumed to be extinct after a mineral vein was shot at, leading to a chain reaction strong enough to blow up a Cylon basestar in close orbit.

 * The Ovions were the only species of the Cylon Alliance to ever appear on screen.
