DistributionMexico (Islas Encantadas Archipelago, Gulf of California)

Type locality: Isla Encantada, Baja California, Gulf of California, México.  
Reproductionoviparous 
TypesHolotype: UA 49549, paratypes: SDSNH 
DiagnosisDiagnosis: Uta encantadae may be diagnosed from U. nolascensis, U. squamata, U. stansburiana, U. antiqua, U. stellata, and U. palmeri by having long and narrow, laterally directed postzygapophyseal processesof the atlas vertebra and a hypertrophied nasal salt gland with the accompanying morphological rearrangements of the rostrum (see above). It differs from U. lowei and U. tumidarostra in having more narrowand elongate frontoparietals that usually are separated by a small azygous scale, having a significantly lower and higher, respectively, mean number of dorsal scale rows and a significantly higher mean number of supraoculars (Table 1), and a much less dense network of turquois spotting on the dorsum. It further differs from U. lowei in having the posterior mylohyoid foramen deep within the angular as opposed to being located between the angular and surangular,weakly as opposedto stronglykeeled dorsals, the presence of a parietal sulcus, orange as opposed to yellow spots in the gular region of adult males, and a dark, as opposed to light, ventrum. It further differs from U. tumidarostra in having undivided prefrontal scales and an offset paravertebral blotching pattern in adult males (Grismer 1994).

CommentAbundance: only known from the type locality (Meiri et al. 2017).

Diet: > 50% of this species’ diet appears to consist of isopoda (Grismer 1994). 
Etymologyhis population was named after the Islas Las Encantadas Archipelago to which it and its presumed closest relatives, Uta tumidarostra and U. lowei, are endemic.
