Definition and diagnosis. Genomic analysis of a pair of Emesis ( Tenedia Grishin, 2019) specimens from Nuevo Leon, Mexico ( Fig. 3 View Figure 3 magenta) reveals that they form a clade sister to E. tenedia ( Fig. 3 View Figure 3 olive) and are genetically differentiated from it at the species level, e.g., their COI barcodes differ by 2.0% (13 bp). Therefore, these two specimens represent a new species. This new species is phenotypically similar to E. tenedia and differs from it by males with typically less elongated and weaker hooked at the apex forewings, more uniform ground color with weaker defined postdiscal paler bands, and weaker expressed gray overscaling along the postdiscal dark narrow band; and by females with less developed pale postdiscal band on the forewing, which is frequently prominent in its anterior half in E. tenedia . Due to the cryptic nature of this species and unexplored phenotypic variation, most reliable identification is achieved by DNA, and a combination of the following base pairs is diagnostic in the nuclear genome: cne603.4.1:A54G, cne9180.2.1:A57T, cne 1600.2.7:T120G, cne498.4.1:C141T, cne498.4.1:T183C, and COI barcode: T92C, T115C, T266C, T427C, T448C.
