Protorthodes mexicana is a moth in the family Noctuidae first described by J. Donald Lafontaine in 2014.

The forewings are pale whitish buff brown with a dusting of pale-brown scales.

The reniform and orbicular spots are slightly darker than the ground color and are outlined in white.

The terminal area is darker than the remainder of the forewing because of more numerous gray-brown scales.

The hindwings are white with a trace of darker scaling on the veins and the wing margin.
