Looks to be a female Potanthus ganda (note abdominal tip).

Potanthus omaha & ganda are very similar.

P. omaha: veins across the bands above & below dark-dusted ,variable.abdominal tip yellow (male).
Ground colour dull ochreous yellow; Underside lightly dark-shaded.

Wear will cause some veins to appear dark, but compare also the veins on the underside of the FW.

TL Seow :Cheers.
PS. Should be a female P. omaha . The veins are out of focus. The large HW spot 6 is also not typical of ganda.
A similar female with the veins in focus.
