The new species was announced Wednesday, but the frogs have been hiding in plain view for more than a century.

"I saw some specimens in museum collections that are over a hundred years old,"co-discoverer Indraneil Das said in a statement.

"Scientists presumably thought they were juveniles of other species,"said Das, a herpetologist atUniversiti Malaysia Sarawakin Malaysia."But it turns out they are adults of this newly discovered microspecies."
