This group of species, with forewings brown and bands formed by large white spots, is very characteristic. It cannot be confused with other species of the Andean cordillera, except for the species of the group
Abdomens were softened in warm 20% KOH for 15 minutes. Scales were removed with a brush. Abdominal sclerites and genitalia were stained with Chlorazol Black E dissolved in distilled water, then dehydrated, positioned and mounted on permanent slides in Euparal. Photographs from slides mounts were made using a Jenoptik ProgRes C10 camera attached to a Leica MZ 16 stereomicroscope. Dissections were photographed with a Nikon CoolPix 4500 Camera attached to a Nikon SMZ-10A stereomicroscope.
Repository abbreviations are as follows:
Tissue samples of the new species described in the present work were processed through DNA barcoding at the Canadian Centre for DNA Barcoding in Guelph (Ontario, Canada), along with many other arctiid species as the target of a DNA barcoding project for neotropical tiger moths, developed within the iBOL
The taxa used in this study are detailed in Table

Morphological differences between the taxa are not obvious, but the pattern of the forewings, in addition to characters of the male and female genitalia, is sufficiently different to easily identify the three species (Table
