Taxonomy:

Cupidonia cupido var. pallidicincta

prairies of Texas near latitude 32° N, USA

Genetic differentiation among all three species of Tympanuchus is very weak, suggesting either that they evolved in isolation during Pleistocene but subsequent secondary contact and hybridization have obscured molecular differences, or that the ancestral species subdivided much more recently, e.g. during the Wisconsin glaciation, such that ancestral genetic polymorphisms remain identifiable#R. Present species is frequently considered a race of T. cupido. Monotypic.

Distribution:

SC USA, in SE Colorado, WC & SW Kansas, W Oklahoma, E New Mexico and W Texas. Historically perhaps also in extreme SW Nebraska.
