Scientists Discover New Andean Lizard Species at Extreme Elevations in Peru

Scientists have identified a new lizard species, Liolaemus archipensis, in Peru’s Arequipa region at elevations above 4,800 meters. Measuring 6 to 8 centimeters, it has sex-specific markings: females have square-shaped spots, while males have oblique patterns and white scales that help it blend into rocky terrain. The lizard eats plants and small arthropods, including spiders, beetles and insect larvae. The discovery, published in the journal Diversity, adds to Peru’s known lizard diversity; the country has 296 species, according to the biologist who led the research.
Liolaemus archipensis belongs to the Liolaemus genus, a diverse group of lizards found across South America.
The lizard was found in the high Andean puna, a high-altitude grassland ecosystem in Arequipa.
Research leader Ling Huamani-Valderrama called the species description “a very important advance for biodiversity in our country.”
