Researchers in the misty mountains of the Ecuadorian Andes have discovered a new species of terrestrial frog and named it after the pioneering British Rock Band Led Zeppelin.  Pristimantis Ledzeppelin, known in English as Led Zeppelin's Rain Frog, was found by the scientists David Brito-Zapata and Carolina Reyes-Puig in the Cordillera del Condor, which straddles south-east Equator and North-east Peru.  The small frog, which has copper-red eyes and a mottled yellow, brown, black and orange skin, is a member of the huge and rapidly expanding Pri stimulus genus.  The genus comprises 569 species-28 of which have been described in Equator in the past two years alone.  The new discovery is reported in the Neotropical Biodiversity Journal.
