Two new species of lizards have been discovered in the Andean highlands of Southern Chile. Collected from areas of heroic past, both small reptiles were named after courages tribal chiefs who have once fought against colonial Spaniards in the Arauco war. The study, conducted by a team of Chilean scientists, is published in the open access journal ZooKeys.

Jaime Troncoso-Palacios from Universidad de Chile and his team found both new species near a lake in a pre-Andean zone among deciduous vegetation. Following the examination of the collected specimens and further analysis of their mitochondrial DNA, performed by Dr. Alvaro A. Elorza from Universidad Andres Bello, Chile, the scientists concluded that they belong to species unknown to science.

One of the species, called Liolaemus janequeoae, or, Janequeo`s Lizard, is distinct for being smaller than its relatives, measuring a maximum of roughly 7 centimeters at length, as well as having no pattern on its back. Both features are quite striking for the group of lizards it belongs to. The only contrasting coloration for the species are several white scales appearing on the upper side in males. Otherwise, the species are predominantly light brown with pearly whitish down side of the body.
