Cecropterus ( Thorybes) nevada (Scudder, 1872) is restricted to OR, CA, and NV and Cecropterus ( Thorybes) dobra ( Evans, 1952) is found eastward in the US

Genomic sequencing of specimens from the northeastern part of the range of the Cecropterus ( Thorybes) mexicana species group that consists of three species: Cecropterus ( Thorybes) nevada (Scudder, 1872) , Cecropterus ( Thorybes) dobra ( Evans, 1952) , and Cecropterus ( Thorybes) mexicana ( Herrich-Schäffer, 1869) reveals that all of them are C. dobra , which is genetically uniform throughout its range ( Fig. 26). Therefore, C. nevada is restricted to the westernmost part of the USA ( Oregon, California, and Nevada) and is separated from C. dobra by a wide gap in its distribution, according to iNaturalist observations (2023) ( Fig. 26).
