Range Description

Taxonomic ambiguities obscure the range of this species. The range minimally extends from the Big Bend region of southwestern Texas south into northern Mexico. Walker et al. (2001) restricted the range of septemvittata (in the strict sense) to Presidio County, Texas, and northeastern Chihuahua; they identified as undescribed species certain additional populations in Texas and Mexico that previously have been allocated to A. septemvittata; moreover, they believed that septemvittata should be treated as a subspecies of A. gularis. Here we provisionally regard A. gularis and A. septemvittata as distinct species and include in the range of A. septemvittata the undescribed species as well as populations assigned to scalaris, which we regard as conspecific with A. septemvittata. Hence the range of A. septemvittata includes several counties in southwestern Texas (Dixon 2000) and the Mexican states of Chihuahua, Coahuila, northeastern Durango, Zacatecas, and San Luis Potosi.
