Grados), in MUSM. Description: FW length: 28.6 mm. Dorsal surface: Ground color of both wings brown (PANTONE® DS 318­1 C), with a complete series of ochre (PANTONE® DS 10­6 C) discal, submarginal and marginal spots on FW. HW with postdiscal spots thick, different from those in  paucartambo, which are arrow­shaped and very evident. Light discal band heavily obscured by dark scales. Ventral surface: General pattern as in  paucartambo, but HW black line bordering marginal yellow lunules heavy and thickened at the distal extremity of the yellow interneural submarginal stripes (in  paucartambothe black line is uniformly thick). Allotype: female, Peru, Cuzco, Cordillera de Vilcabamba, 3350 m, 11°40’S, 73°40’W, 8.VI.1997(J. Grados), in MUSM. Description: FW length: 28,6 mm. Dorsal surface: Somewhat lighter ground color. Light markings more evident and slightly more extensive on both FW and HW. HW with postdiscal spots larger than in male, oval. Discal band not heavily obscured by dark scales. Ventral surface: Like the male.  Paratypes( 23 males, 2 females): Same data as holotype, but dates between 8 and 20.VI.1997(J. Grados; G.
