Identification
Distinguished from similar Protorthodes by: (1) more irregular pale subterminal ; (2) concentration of dark sagittate marks to subterminal line specifically in area to spot; (3) maculation pattern details; (4) structure; (5) male characteristics. Formerly recognized forms 'P. indra' (pale xeric ) and 'P. daviesi' (high-contrast morph) now synonymized under P. incincta.

Appearance
length 11–14 mm. Ground color highly variable: pale whitish-grey through of , orange, and grey to blackish-grey. Pale subterminal irregular in shape. Dark sagittate (arrow-shaped) marks concentrated to subterminal line in area to spot. Palest forms occur in xeric regions of Nevada, Arizona, and New Mexico. Most contrastingly marked forms found in southern Wyoming, Colorado, and northern New Mexico.
