Baird, 1859[2]

It was originally described by Baird in 1859 as having a head that was two-fifths the size if the head and body, was a light pea-green spotted with darker green and with a white underside.[2]

It can be distinguished from the Mojave fringe-toed lizard and the Coachella Valley fringe-toed lizard by its orange/pinkish stripes on the sides of its underside, while the backs have much similar appearances.[5]

The former subspecies Uma notata rufopunctata has had an unsettled taxonomy,[3] and in 2016 was found to represent a hybrid between Uma notata and Uma cowlesi.[6]

Habitat

The Colorado Desert fringe-toed lizard (Uma notata) occupy the vast windblown sands of the Algodones Dunes in Imperial County, California and crossing the border into Sonora, Mexico.[7]
