Hesperia pahaska Leussler, 1938 populations in most of New Mexico and the White Mountains , Arizona are the nominal subspecies, not H. p. williamsi Lindsey, 1940

Genomic trees of Hesperia pahaska Leussler, 1938 (type locality in USA: Nebraska, Sioux Co.) reveal that a specimen from southeastern New Mexico (Lincoln Co., NVG-22057C03) and specimens from the White Mountains in Arizona are not in the same clade with Hesperia pahaska williamsi Lindsey, 1940 (type locality in USA: Arizona, Pima Co. Baboquivari Mts., holotype sequenced as NVG-15096B10), a subspecies they were usually attributed to, but are within specimens of the nominal H. pahaska ( Fig. 42). Therefore, we deduce that populations in most of New Mexico and eastern Arizona are H. pahaska pahaska , while the specimens from southwestern New Mexico remain to be studied.
