Abstract
Cnemidophorus tesselatus is an allodiploid, parthenogenetic lizard comprised of a number of distinctive tokogenetic arrays (Frost and Hillis, 1990) presently identified by four color pattern class descriptors: C, Colorado D, New Mexico D, and E (Taylor et al., 1996; Walker et al., 1997). The macrogeographic relationships of these pattern classes were outlined in Zweifel's (1965) pioneering study of geographic variation in Cnemidophorus tesselatus. Pattern class C was known to exist isolated from the other pattern classes in parts of southeastern Colorado, northwestern Oklahoma, and northwestern Texas. Sympatry between pattern classes C and D was known to occur only in the vicinities of the historic townsite of Higbee, Otero County, Colorado, and Conchas Lake, San Miguel County, New Mexico. Pattern class E occurred to the south, with specimens from Fort Sumner, De Baca County, New Mexico, approximately 105 km south of the Conchas Lake locality, documenting the closest proximity of pattern class E to pattern classes C and D.
