Side-blotched lizards are lizards of the genus Uta. They are some of the most abundant and commonly observed lizards in the deserts of western North America.
[edit] Systematics
The systematics and phylogeny of the side-blotched lizards is very confusing, with many local forms and morphs having been described as full species (e.g. see Oliver, 1943). Following the review of Upton & Murphy (1997) which included new data from mtDNA cytochrome b and ATPase 6 sequences, the following species can be recognized pending further research:
- Eastern Side-blotched Lizard, Uta stejnegeri - previously considered a subspecies of U. stansburiana
- San Pedro Martir Side-blotched Lizard, Uta palmeri
- Angel de la Guarda Side-blotched Lizard (undescribed species, previously included in U. stansburiana)
- Salsipuedes Side-blotched Lizard, Uta antiqua - previously considered a subspecies of U. stansburiana
- Santa Catalina Side-blotched Lizard, Uta squamata - sometimes considered a subspecies of U. stansburiana
- San Esteban Side-blotched Lizard (undescribed species, previously included in U. stansburiana)
- San Pedro Nolasco Side-blotched Lizard, Uta nolascensis
- Common Side-blotched Lizard, Uta stansburiana
- Western Side-blotched Lizard, Uta (stansburiana) elegans
- Enchanted Side-blotched Lizard, Uta encantadae - possibly a subspecies of U. stansburiana
- El Muerto Side-blotched Lizard, Uta lowei - possibly a subspecies of U. stansburiana
- Swollen-nosed Side-blotched Lizard, Uta tumidarostra - possibly a subspecies of U. stansburiana
- Socorro Side-blotched Lizard, Uta auriculata - possibly a subspecies of U. stansburiana
- Clarion Side-blotched Lizard, Uta clarionensis - possibly a subspecies of U. stansburiana
- Ornate Side-blotched Lizard, Uta mannophora - possibly a subspecies of U. stansburiana
Uta stellata and U. concinna are nowadays usually considered a subspecies of U. stansburiana. U. encantadae, U. lowei and U. tumidarostra might be subspecies of a distinct species (Las Encantadas Side-blotched Lizard) instead. Similarly, U. auriculata and U. clarionensis might be subspecies of a single species, the Revillagigedo Side-blotched Lizard.
