Reassessment of Amblyscirtes hegon (Hesperiidae) as a complex of four distinct species revealed by genomic analysis

After the discovery of a unique phenotype in the southern United States with a different ventral ground color than nominotypical Amblyscirtes hegon (Scudder, 1863), which occurs in the northeastern United States, genomic analysis revealed that A. hegon is a species complex. Phenotypic, genitalic, and genomic differences of the complex are presented here. Four species are identified: A. hegon; A. nemoris (W. H. Edwards, 1864), stat. rest.; A. matheri Patterson, Pavulaan & Grishin, sp. n. (TL: USA, Mississippi, Warren Co.); and A. gelidus Grishin, Patterson & Pavulaan, sp. n. (TL: USA, Michigan, Van Buren Co.).
