  • Original description
  • Type locality: USA: Texas, Hidalgo Co., McAllen
    This species is sister to E. cruza. In facies, the following characters separate the species from E. cruza: on the forewing, the hyaline spot in cell CuA2-1A+2A is offset farther distad from spot in cell CuA1-CuA2, (the two spots are closer together in E. cruza and are frequently larger) and the discal cell spot is rounder, not as strongly crescent-shaped as in typical E. cruza; on the ventral hindwing, the silver spot near the end of the discal cell more offset basad from the larger silver spot and is slightly more distant from that larger spot than in E. cruza, the area between the silver spots (both, in discal cell and between veins 1A+2A and M3) and a postdiscal band of faint white spots is mostly of dark ground color and largely devoid of pale overscaling, in particular between the discal cell spot and the postdiscal spot between the veins M1 and M3, the white spots in the postdiscal band are narrower and less diffuse that in E. cruza, pale lavender submarginal overscaling reaches the white postdiscal band, in particular in the middle and mostly in the cell CuA1-CuA2 (separated from the band with ground color brown scales in E. cruza, noticeably in the cell CuA1-CuA2, especially if white overscaling is poorly expressed between the discal silver spots and the postdiscal white band). In other words, lavender/white overscaling in E. cruza is expressed first between the discal silver spots and the postdiscal white band, but in this species, it is expressed first between the postdiscal while band and marginal pale-lavender area (which are frequently merged with each other as a result). The holotypes of both taxa reflect this tendency well.
