This large species inhabits the Mexican Plateau and the Cordillera Volcánica, but not the Sierra de Coalcomán, where apparently it is replaced by _Sceloporus bulleri_. _Sceloporus torquatus torquatus_ usually is found in pine or pine-fir forests at elevations between 1450 and 3000 meters. In many places it is almost entirely arboreal, but in areas where there are many fallen trees or rock fences and rock piles, many individuals have been found on the ground near the rocks or logs. In the coniferous forests this species is associated with _S. grammicus microtepidotus_ and _S. aeneus aeneus_. The distinction made by Smith (1938:572) between the subspecies _S. torquatus torquatus_ and _melanogaster_ is slight. Individuals with pale bluish spots are found throughout the range of the species in Michoacán; spotting is especially evident in the young. Individuals having an incomplete nuchal collar have been found at Maravatio and at Zinapécuaro in the northern part of the state; in this character these specimens resemble _S. torquatus melanogaster_, which is found to the north from Guanajuato to Zacatecas and San Luis Potosí. ~Sceloporus utiformis~ Cope _Sceloporus utiformis_ Cope, Proc.

In Michoacán the range of this species is discontinuous. It has been found between 1050 and 1550 meters on the slopes of the Cordillera Volcánica, and on the coast and seaward slopes of the Sierra de Coalcomán up to an elevation of 900 meters. It is absent from the Tepalcatepec Valley. At Uruapan and at Cascada Tzararacua this lizard was found on the ground in oak forest or in open pine-oak forest; on the coast and foothills of the Sierra de Coalcomán it was found on the ground in the gallery forests along streams, and not in the scrub forest. ~Urosaurus bicarinatus tuberculatus~ (Schmidt) _Uta tuberculata_ Schmidt, Amer.
