Checking the checkered taxonomy of Plötz's checkered skippers (Hesperiidae: Pyrgini).

We present an analysis of the names proposed by Carl Plötz in 1884 for the New World species in the genus Hübner, [1819] facilitated by the genomic sequencing of extant primary type specimens comparatively with a larger sample of more recently collected specimens of these species and their relatives. The changes to nomenclature suggested here are only caused by the identity of primary type specimens as revealed by their phenotypes or through genomic sequencing. All neotypes are designated to stabilize nomenclature in agreement with the current usage of these names, which in unison agrees best with the information available about them. are designated for the following 5 taxa: [sic] Plötz, 1884 (type locality Argentina: Buenos Aires), Plötz, 1884 (type locality in Brazil: Minas Gerais), Plötz, 1884 (type locality in Mexico), [sic] Plötz, 1884 (type locality in "Central America", likely southern Mexico), and Skinner, 1906 (type locality USA: Texas, San Antonio). are designated for the following 4 taxa: Plötz, 1884 (Herrich-Schäffer in litt.) (type locality Colombia: Bogota), [sic] Plötz, 1884 (type locality Colombia: Bogota), [sic] Plötz, 1884 (Herrich-Schäffer in litt.) (type locality in Mexico: Nuevo Leon), Plötz, 1884 (Herrich-Schäffer in litt.) (type locality in "Central America", likely southern Mexico). As a result, and are objective synonyms. The following are junior subjective synonyms: of (Plötz, 1884), [sic] Plötz, 1884 of (Stoll, 1780) and of (Linnaeus, 1767). (Plötz, 1884) is a species-level taxon and not a subspecies of (Erichson, [1849])). Genomic analysis of the lectotypes of , , and establishes them as conspecific with (Grote, 1872), thus depriving a distinct species currently identified as from its name, that becomes a name for (Plötz, 1884) in accord with its lectotype identity; and are its junior subjective synonyms, but is a junior subjective synonym of . A new name Grishin (type locality USA: Arizona, Cochise Co., Portal) is proposed for the species misidentified as . Furthermore, genomic comparisons reveal two other new species and one new subspecies of Grishin, 2019: Grishin (type locality Mexico: Veracruz, Huatusco), Grishin (type locality Ecuador: Pichincha, Tandapi), and Grishin (type locality Curaçao: Hato Field) that are cryptic and can be confidently identified only by their genotype.
