In 1853 Edward Frederick Kelaart, a physician and naturalist, collected a strange frog on the island of Sri Lanka then a British colony known as Ceylon. The specimen was a large shrub frog (about 2 inches or 5.5 centimeters long) with black-outlined white specks on lime-green skin. He dubbed it “starry” after its pale specks, but that was last anyone heard of it. Even the holotype—the body of the amphibian collected by Kelaart—went missing. Fast forward nearly 160 years—two world wars, Sri Lanka’s independence, and a man on the moon—when a recent expedition into Sri Lanka’s Peak Wilderness rediscovered a beguiling frog with pinkish specks.

“These quite stunning frogs were observed perched on leaves in the canopy. They were slow moving, we collected samples which we thought were new species. But after reviewing past work, [especially] extinct species, it was evident that this was Pseudophilautus stellatus,” L.J. Mendis Wickramasinghe told mongabay. Kelaart’s starry shrub frog, or Pseudophilautus stellatus, had been re-discovered.
