This is one of the most abundant and widespread lizards in the Tepalcatepec Valley. Throughout its range it is ecologically associated with Cnemidophorus costatus zweifeli, which ranges to elevations somewhat higher than the 1050 meters known for C. deppei infernalis. This small lizard reaches its greatest abundance in grassy areas on the floor of the Tepalcatepec Valley, where in the Cercidium-Prosopis-Apoplanesia associations it occurs with Cnemidophorus calidipes.
Duellman and Wellman (1960) discussed the variation and relationships of Cnemidophorus deppei, of which the subspecies infernalis is restricted to the Balsas-Tepalcatepec Basin.
Cnemidophorus lineatissimus exoristus Duellman and Wellman
Cnemidophorus lineatissimus exoristus Duellman and Wellman, Misc. Publ. Mus. Zool. Univ. Michigan, 111:44, February 10, 1960.—Rancho Santa Ana, four kilometers northeast of San Salvador, Michoacán, México.
Thirteen to 25 km. S of Arteaga (18); Capirio (19); Limoncito (13); Santa Ana (22).
As in Cnemidophorus calidipes, the distribution of this subspecies seems to be restricted to the Tepalcatepec Valley, except in the vicinity of Arteaga, where it occurs on the southern slope of the Sierra de Coalcomán. As pointed out by Duellman and Wellman (1960:46), the specimens from south of Arteaga are like those from the Tepalcatepec Valley in scutellation and coloration, and not like Cnemidophorus lineatissimus lividus from the geographically closer coastal lowlands.
In the Tepalcatepec Valley Cnemidophorus lineatissimus exoristus inhabits gallery forests along the larger streams; in this habitat it is associated with Ameiva undulata sinistra. From the other species of Cnemidophorus in Michoacán, C. lineatissimus exoristus can be distinguished by the possession of seven longitudinal stripes in adults and by the characters of scutellation given in Table 5.
