DescriptionProtorthodes incincta is so variable in appearance that it is almost easier to identify it be eliminating the other species. The ground color varies from pale whitish gray, through various shades of brown, orange, and gray to blackish gray. Forewing length varies from 11–14 mm. The moths are most likely to be confused with those of Protorthodes curtica that mainly occurs father to the west. Protorthodes incincta can be distinguished by the more irregular pale subterminal line, concentration of dark sagittate marks proximal to the subterminal line to the area distal to the reniform spot, and other characters of maculation, antenna, and male genitalia listed under Protorthodes curtica. The palest forms (e.g., Fig. 16) occur in xeric areas of Nevada, Arizona and New Mexico and previously were known as Protorthodes indra, and the most contrastingly marked forms (e.g., Figs 11, 12) are localized in southern Wyoming, Colorado, and northern New Mexico and previously were known as Protorthodes daviesi. However, both forms blend into more typical forms in these areas and do not differ in structural characters or barcodes from other populations.
