Discussion | Erythranthe inconspicua occurs in Sierran counties from Kern north to El Dorado and then is apparently disjunct further northward to Butte County. A record from Los Angeles County (Bigelow s.n., 14 May 1854, the type of the species) is probably mislabeled, as other collections by Bigelow on the same day are from Calaveras County.

Erythranthe erubescens was long identified as E. lewisii but is distinct in its light pink corollas (versus mostly magenta-rose to purplish in E. lewisii), more broadly cylindric calyx tube [14–19 × 6–8 mm versus 12–15(–17) × 9–12 mm], and its geographic range in the Sierra Nevada of California (versus widespread from southern Alaska south to northwestern California, northern Utah, eastern Nevada, and northern Colorado in E. lewisii). The two are genetically isolated and phylogenetically distinct (see summary of evidence in G. L. Nesom 2014b). In California, Erythranthe erubescens ranges from Modoc, Plumas, and Tehama counties south to Fresno County; in Nevada, it is known only from Washoe County and Carson City.
