Definition and diagnosis. Both genomic sequences and genitalia characters (valva with knobs distally and without a long process from the ampulla) place this species in the nominal subgenus Drephalys E. Watson, 1893 . However, the yellow colors of the spots and the wing patterns show some similarity to species from the subgenus Paradrephalys Burns, 2000 . The closest in appearance and the only known nominotypical dorsally yellow-patterned Drephalys with ventral hindwing pale spots instead of a band is Drephalys opifex Evans, 1952 (type locality in Suriname). The new species keys to it (B.6.8) in Evans (1952), although not precisely, because the hindwing base in the new species is ventrally orange infused with purple instead of yellow, and palpi are whiter. More specifically, it differs from all described Drephalys species by a combination of honey-yellow markings on the dorsal wing surface (cell Rs-M 1 with a yellow spot), two prominent oval white spots on the purple-orange ventral hindwing, and the lack of costal fold. In DNA, a combination of the following base pairs is diagnostic in the nuclear genome: aly1146.54.9:A585G, aly1146.54.9:A591T, aly275211.5.3:A92G, aly 2284.4.3:T87C, aly 2284.4.3:T148C, aly113.11.7:C105C (not T), aly113.11.7:C138C (not T), aly 2363.7.5:G102G (not A), aly525.90.3:G21G (not C), aly10226.17.2:C63C (not T), and COI barcode: T268T, T274A, T475C, T487C, C536C.
