The frog Alsodes vittatus is an elusive creature – described in 1902, it managed to go undetected for more than a century. Now, after a decade of investigation, a research team has rediscovered it, in its first sighting after 130 years.

Researchers from the Laboratory of Systematics and Conservation of Herpetozoa (SyCoH) of the University of Concepción, Chile – Dr. Claudio Correa, engineer in renewable natural resources Edvin Riveros Riffo, and biologist Juan Pablo Donoso, have published their extraordinary discovery in the journal ZooKeys.
Alsodes vittatus was scientifically described in 1902 by Rodulfo Amando Philippi, a German naturalist living in Chile. French entomologist Philibert Germain had discovered the species in 1893 at the former Hacienda San Ignacio de Pemehue in La Araucanía Region, Chile, and brought three specimens to Philippi for description. Since then, no one has seen the species again, despite multiple search efforts.
