Melanolophia canadaria is extremely similar, but usually has more dark mottling in the wings, and usually has a noticeably denticulate PM line as opposed to the typically more sinuous (somewhat "straighter") PM line of signataria. Poorly marked or heavily mottled specimens can be very difficult to distinguish.
