I've seen the darker A. remellalis in AZ and looked at the images here and on BOLD. It's not the best situation to determine a species mainly by color, especially when there seem to be conflicting images (light & dark) included in each taxon, but this one seems to fit best here. There was also a very gold-colored individual seen around the same time that looked quite different and I suspect might be A. concha. I'm not confident enough, though, and will place that other one at genus level.
