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.

northeast of San Salvador, Michoacan, Mexico.

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 Coalcoman. 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 Michoacan, _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.
