Taxonomic Comments
Formerly in the genus Eumeces. Smith (2005) and Brandley et al. (2005) formally proposed that all North American species (north of Mexico) be placed in the genus Plestiodon. In a phylogenetic analysis of Eumeces based on morphology, Griffith et al. (2000) proposed splitting Eumeces into multiple genera, based on the apparent paraphyly of Eumeces.

There has been disagreement over whether the southern subspecies should be called E. m. epipleurotus or E. m. gaigeae (see Hammerson 1999). The name eplipleurotus went long unused but has priority, and a recent informal ICZN evaluation concluded that epipleurotus is the name that should be used (Axtell and Smith 2004). Hammerson (1999) suggested that the variable skink (subspecies epipleurotus) might be a distinct species; genetic study is needed to resolve the question.

Range Extent200,000-2,500,000 square km (about 80,000-1,000,000 square miles)
Number of Occurrences81 - 300
Range Extent Comments
The northern part of the geographic range includes southern South Dakota, Nebraska, southeastern Wyoming, and northeastern Colorado; the southern segment encompasses southern Colorado, southeastern Utah, Arizona, New Mexico, western Texas, and possibly Chihuahua. Elevational range is 910-2,620 meters (3,000-8,600 feet) (Stebbins 2003).
Occurrences Comments
This species is represented by a large number of occurrences or subpopulations. For example, Degenhardt et al. (1996) mapped 70-75 collection sites in New Mexico. Hammerson (1999) mapped about 60 localities in Colorado. The species is secretive and undoubtedly occurs in sites not yet documented.
Threat Impact Comments
In prairie and shrubland regions, conversion of habitat to agricultural uses has caused local declines.
Ecology & Habitat

Habitat

Northern populations inhabit prairie grassland and sandhills; southern populations occur in creosote bush desert, streamside thickets, pinyon-juniper and pine-oak woodland, fir forests, semidesert and oak shrublands, vacant lots, dumps; soil may be rocky, sandy, or loamy (Degenhardt et al. 1996, Hammerson, 1999, Stebbins 2003). This is a secretive lizard that is usually found under ground cover. Eggs have been found under rocks.

Reproduction

Lays 2-7 eggs, May-June; eggs attended by female, hatch in July or August (Stebbins 1985, Hammerson 1982, Fitch 1970).
