Milanion pilumnus var. hemestinus Mabille and Boullet, 1917 is a junior subjective synonym of Milanion pilumnus pilumnus Mabille and Boullet, 1917 not of Milanion leucaspis (Mabille, 1878)

Genomic sequencing of the lectotype of Milanion pilumnus var. hemestinus Mabille and Boullet, 1917 (type locality in Peru) reveals that it is in a clade different from Milanion leucaspis (Mabille, 1878) (type locality in Brazil), which is its current senior subjective synonym but is placed among specimens of Milanion pilumnus Mabille and Boullet, 1917 (type locality in Bolivia and Peru). COI barcodes of the M. p. hemestinus lectotype and a syntype of M. pilumnus pilumnus differ by 0.5% (3 bp). Therefore, as proposed by the original authors, M. p. hemestinus is conspecific with M. pilumnus , and we treat these two names as synonymous.
