-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.
Wickramasinghe,
the lead author of the paper announcing the discovery in Zootaxa, says one
reason why the starry shrub frog remained undetected for so long was its
habitat.
"We
worked in [parts of the Peak Wilderness Sanctuary] where previous studies had
never taken place, in tough and rugged conditions, so hardly any researchers
had actually gone to these sites," he explains.
In all the
scientists identified 78 individuals during their surveys, but given its
scarcity and likely small habitat, Wickramasinghe believes the species should
be listed as Critically Endangered. The species is currently imperiled by
expanding tea plantations, illegal gem mining, pollution from religious
pilgrims, and forest dieback.
