Description
Herein, we report the first observation of two different coloration patterns in Chilean snakes. Based on the alteration of wild coloration patterns, a juvenile specimen of Tachymenis chilensis coronellina Werner, 1898 was diagnosed with albinism and a juvenile specimen of Tachymenis chilensis chilensis (Schlegel, 1837) was diagnosed with leucism. The existence of color variations in wild snake populations and the implications of these for fitness are discussed.
