The wing wear could explain the lines, some BOLD ones do have narrower lines. The black fringe is a problem however - all the BOLD specimens have yellow fringes.
Maybe it is the hindwing fringe extending beyond the forewing. One of the BOLD (Hobern) specimens has a wide dark fringe on the hindwings. https://bold-au.hobern.net/specimen.php?processid=ANICD925-10
