Is there a reliable field mark or anything to differentiate this species from M. semifasciata?

My specimens were all determined for me. But even back then I was told the whole genus is questionable as to which are valid species. When you view a large series of each, what I tend to see is a fatter white line on erectifascia than the others. Plus the base color of the wings seem a light to average brown in semifasciata, and a very rich chocolate brown in erectifascia.
