Sarmientoia dinka Evans, 1952 is a new junior subjective synonym of Adina adrastor (Mabille and Boullet, 1912)

Genomic sequencing of three specimens (1♁ and 2♀♀) from Brazil: Rio de Janeiro identified by phenotypic comparison as Salantoia dinka (Evans, 1952) (type locality not specified) (Fig. 1a cyan, d–f), known only from a single male holotype without a locality label (Fig. 1c), reveals that the holotype of Adina adrastor (Mabille and Boullet, 1912) (type locality in South America) (Fig. 1a magenta, b), a female, falls within their genetic variation. COI barcodes of the A. adrastor holotype and the specimens from Brazil differ by 0.46-0.6% (3-4 bp), and the specimens from Brazil show difference of 0.46% (3 bp) among them. Females from Brazil (Fig. 1e, f) are phenotypically similar to the holotype of A. adrastor, and a male (Fig. 1d), which is conspecific with the females as evidenced by DNA, is phenotypically close to the holotype of S. dinka . It is most likely that S. dinka is a male of female A. adrastor, the name kept in synonymy with Bungalotis midas (Cramer, 1775) (type locality in Suriname) since Evans (1952), who regarded this unique female as “an aberration without the spot in space 3 upf”, until it was sequenced, resurrected from synonymy, and designated as the type species of a new genus Adina Grishin, 2022 (Zhang et al. 2022). Therefore, we propose that Salantoia dinka (Evans, 1952), syn. nov. is a new junior subjective synonym of Adina adrastor (Mabille and Boullet, 1912) . Then, we hypothesize that the type localities of both S. dinka and A. adrastor are in Southeast Brazil, possibly around Rio de Janeiro.
