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. Richmond (2006) found a substantial division between mtDNA haplotypes of eastern and western P. laticeps but did not draw any taxonomic conclusion from it (Crother 2017).

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. See Murphy et al. (1983) for information on the relationships among E. inexpectatus, E. fasciatus, and E. laticeps.

Range Extent200,000-2,500,000 square km (about 80,000-1,000,000 square miles)
Number of Occurrences> 300
Range Extent Comments
The range extends from southeastern Pennsylvania, central Ohio, Indiana, Illinois, Missouri, and eastern Kanas south to eastern Texas, the Gulf Coast, and central Florida. An isolated population may occur in northeastern Indiana (record could represent an atypical E. fasciatus juvenile; Minton 2001 ). Isolated questionable records exist west of established range in western Oklahoma and central Texas, and to the south in southern Florida (Cooper 1988).
Occurrences Comments
This species is represented by a very large number of occurrences or subpopulations. Cooper (1988) mapped hundred of collections sites rangewide, and Palmer and Braswell (1995) mapped well over 100 sites in North Carolina alone.
Threat Impact Comments
No major threats have been identified. The species is tolerant of moderate habitat alteration (e.g., logging, partial clearing, nonintensive rural residential development).
Ecology & Habitat

Habitat

Rangewide, the species occupies wooded areas and woodland edges having diverse soil types and moisture conditions; hammocks and cypress heads in Florida; also swamps, vacant debris-strewn lots, and barrier islands. These lizards are semiarboreal and often sun themselves on snags or stumps; they take refuge in rotting stumps and standing dead trees, occupying old woodpecker holes and other hollows. On coastal islands in South Carolina, they prefer large live oaks having holes and a fringe of dense cover (bushes) (Cooper 1993); adults occur most often in oaks or on the ground, juveniles occur most often on walls, palmettos, or on the ground; they may actively avoid pines (Cooper and Vitt 1994). Eggs are laid in a nest in a rotting stump or dead tree or under rocks or other cover.

Reproduction

Eggs are laid during May-July (June in South Carolina). Clutch size is 6-18 (average about 14). Female attends eggs until hatching, about 48 days in South Carolina; hatching occurs from late July to mid-August in South Carolina. Sexually mature in 21 months. Females breed annually (Vitt and Cooper 1985). Large males guard adult females (exclude smaller males) during the breeding season (Cooper 1993).
