Definition and diagnosis. Phylogenetic trees reveal that specimens from Mexico and Guatemala identified as Cymaenes laureolus (Schaus, 1913) (type locality in Costa Rica, holotype sequenced as NVG-15109B05) are not monophyletic with it and show prominent genetic differentiation from it in the Z chromosome ( Fig. 6), although their COI barcodes differ by only 0.9% (6 bp), and therefore represent a new species. This new species keys to Cymaenes laureolus laureolus (J.27.6(a)) in Evans (1955) but differs from it by better developed white subapical spots on forewing and more prominent pale areas on ventral hindwing that are tinted with purplish brown rather than plain brown ( Fig. 155–156), valva is broader, more square, and teeth on the harpe are more prominent ( Fig. 382–383). Due to the cryptic nature of this species, most reliable identification is achieved by DNA and a combination of the following base pairs is diagnostic in the nuclear genome: aly1249.14.4:C96T, aly1249.14.4:A147G, aly527.6.11:A63G, aly594.19.2:C72T, aly3936.3.3:C88T, and does not consistently differ from its close relatives in COI barcode.

Type locality. Mexico: San Luis Potosí, La Mera Ceiba, elevation 700 ft.

Etymology. In Greek, μελανό (melano) means dark, and πορφύρα (porphyra) means purple. The name is given for the purplish sheen of the ventral hindwing in this dark-brown species and is an adjective.

Distribution. Currently known from Mexico and Guatemala.
