 Definition and diagnosis. Phylogenetic analysis reveals that specimens from eastern Ecuador identified as Myrinia binoculus (Möschler, 1877) (type locality in Suriname, syntype sequenced as NVG-15033C11) are genetically differentiated from it in both nuclear and mitochondrial genomes (Fig. 2): e.g., their COI barcodes differ by 1.8% (12 bp), and therefore represent a new species. This new species keys to M. binoculus ((E.24.1) in Evans (1953) and differs from it by more elongated eyespot on the dorsal forewing, wider dark-brown forewing margins, better defined and more contrasting from the ground color bands (discal, postdiscal, and submarginal) on the ventral hindwing, and a smaller dark ventral hindwing tornal spot (Fig. 61–62). 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: aly2178.55.2:C48T, aly2178.55.2:C63T, aly1084.13.12:C93T, aly276558.43.4:A408G, aly4645.9.3:T103C, and COI barcode: A43G, A79G, T97C, A166G, A184G, A586G.
