Definition and diagnosis. Phylogenetic analysis reveals that a specimen from Guatemala identified as Myrinia myris (Mabille, 1898) (type locality in Brazil: Santa Catarina ) is genetically differentiated from it ( Fig. 2): e.g., their COI barcodes differ by 3.2% (21 bp), and therefore represents a new species. The new species keys to M. myris (E.24.2) in Evans (1953) and differs from it by more contrasting wing patterns: dark bands and spots stand out on paler ground color stronger than in M. myris , e.g., forewing subapical dark spots. 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: aly528.33.1:T420A, aly707.3.1:G46A, aly315.8.2:G129C, aly536.208.9:A36G, aly4645.9.3:T87A, aly728.25.1:T72T (not A), aly 1475.3.2:G1077G (not A), aly600.8.1:G81G (not A), aly1720.13.9:C206C (not A), aly1350.21.3:T54T (not C), and COI barcode: A208G, A238A, T287C, A298T, T601C.

Type material. Holotype: ♂ deposited in the National Museum of Natural History , Smithsonian Institution, Washington, DC, USA ( USNM), illustrated in Fig. 65–66, bears the following four rectangular labels, three white: [fromLThiel | SSebastian | Retalhuleu | Guatemala], [DNA sample ID: | NVG-18061H04 | c/o Nick V. Grishin], [USNMENT | {QR Code} | 01466905], and one red [HOLOTYPE ♂ | Myrinia | maculosa Grishin ].

Type locality. Guatemala: Retalhuleu department, San Sebastián.

Etymology. In Latin, maculosa means spotted, speckled, dappled, mottled, or variegated. It reflects a more contrasting and spottier wing pattern compared to its closest relatives. The name is an adjective.

Distribution. Currently known only from the holotype collected in Guatemala.
