Coloration patterns in wildlife species are basic adaptations for the survival of populations, acting in camouflage, mimicry, sexual selection and thermoregulation. Atypical cases of coloration of taxa are also common, such as leucism, which is a hypopigmentary variation of the skin or fur, which occurs throughout or partially on the body. Leucism has been associated with environmental factors, such as anthropized habitat, low-quality diet, radioactive contamination and effects of anthropogenic actions. Likewise, individuals with leucism are more frequent in small and isolated populations since inbreeding increases the possibility of recessive alleles being expressed. Despite the few records, several cases have been documented in rodents over time. During April and May 2020, the activity of a gopher with total leucism that inhabited a niche fragmented by a residential villa and a golf course was monitored. This work presents the first known case of leucism in Cratogeomys merriami for the State of Mexico.
