Pyrgus barrosi Ureta, 1956 is a subspecies of

Chirgus (Chirgus) biseriatus (Weymer, 1890)

Genomic phylogeny that includes several specimens of Chirgus biseriatus (Weymer, 1890) (type locality in Bolivia, lectotype sequenced as NVG-15033H08, brown ground color of dorsal hindwing) and Chirgus barrosi (Ureta, 1956) (type locality in Chile, several topotypical paratypes sequenced, cream and nearly unmarked dorsal hindwing) reveals the lack of separation between them in nuclear genomes, although the mitochondrial genomes partition them into different clades ( Fig. 109 ). Due to the lack of nuclear genomic differentiation, we propose to treat these two taxa as subspecies with the junior name being Chirgus (Chirgus) biseriatus barrosi Ureta, 1956 , stat. nov. In summary, we show that C. biseriatus is not a synonym of C. limbata , but a species previously known as C. barrosi , which, due to wing pattern differences and separate geographic ranges, becomes a subspecies.

Primary type specimens are labeled in red. Branches corresponding to different species are colored in different colors: C. biseriatus (purple), C. nigella (cyan), C. limbata (green), C argentinus sp. n. (orange), C. trisignatus (blue), C. teres sp. n. (red), C. sombrus sp. n. (magenta), and C. bocchoris (aquamarine).
