Haha welcome back Primogen and yes, you nailed it.
The Atomic Worm Lizard occurred on Hermite Island off the Australian coast. In 1956 the British government conducted nuclear weapon testing on the island and this little lizard APPARENTLY became extinct.
A similar species was discovered on mainland Australia and a debate ensued whether it is the same species or not. In 2006 the Atomic Worm Lizard was rediscovered on Hermite Island and subsequent surveys found the same Lizard on numerous islands in the vicinity.
By the way, later mDNA testing did confirm that the population on the mainland is exactly the same species as all the insular populations.
