Eurema andersonii
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.

Too dificult & vague. Most likely Isma iapis.

Most likely Isma iapis.

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.

This shot in which the FW have two large cellspots is of another species.
