There is only one cellspot & the inclination of the FW black border in space 2, 3 is as for andersoni.
Just that the markings are heavy.
The FW cellspots, upper small & lower elongate is seen in many Isma ssp (variable feature).
FW spot 2 is quadrate; there is no spot in space 1b, & the HW does not seem to have hyaline spots.
There appearance is that of Isma iapis or protoclea. https://yutaka.it-n.jp/hes/91880001.html https://yutaka.it-n.jp/hes/91890020.html
