Decinea onasima (Hewitson, 1877) with Cobalus boliviensis E. Bell, 1930 as its subspecies and Decinea formosus (Hayward, 1940) are species distinct from Decinea dama (Herrich-Schäffer, 1869)

Genomic analysis of primary type specimens of the following four taxa: Hesperia onasima Hewitson, 1877 (type locality in Brazil: Rio de Janeiro, syntype sequenced as NVG-18043C12), Cobalus boliviensis E. Bell, 1930 (type locality in Bolivia, holotype sequenced as NVG-18025E07), Cobalus formosus Hayward, 1940 (type locality in Ecuador, holotype sequenced as NVG-18025H07) and Cobalus dama Herrich-Schäffer, 1869 (type locality not specified, syntypes sequenced as NVG-15036H04 and NVG-18042G04), the former three of which are currently regarded as junior subjective synonyms of the latter, placed in the genus Decinea Evans, 1955 (type species Hesperia decinea Hewitson, 1876 ), reveals that they represent three genetically differentiated non-sister lineages ( Fig. 4). COI barcodes of D. dama differ from either H. onasima or C. formosus by 7.9% (52 bp). However, H. onasima and C. boliviensis are more closely related to each other ( Fig. 4). Therefore, we propose to reinstate Decinea onasima (Hewitson, 1877) and Decinea formosus (Hayward, 1940) as species-level taxa and, for the time being, pending further studies, treat Decinea onasima boliviensis (E. Bell, 1930) , new combination, as a subspecies.
