Scientists in Peru have identified a new lizard species, Liolaemus archipensis, living above 4,800 metres in the southern Andean region of Arequipa, the Natural History Museum of San Marcos University announced. The small reptile, six to eight centimetres long, was described in the journal Diversity and brings the number of lizard species known in Peru to about 296. Lead biologist Ling Huamani-Valderrama called it an important advance for the country's biodiversity, which has also yielded dozens of new species in the Amazon in recent years.
