Post 5.
There are about 20 species of Potanthus species in Thailand & their IDs can be very difficult from fieldshots.


Potanthus no. 1; Male on the left ,female on the right.
Male abdominal end not black-banded ,FW spots overlapping HW spot 6 absent; Female FW spots no overlap between spot 5 & 6; HW spot 6 present.
Underside dark shaded.

Three species have the abdominal end yellow without a black band. namely P. omaha, ganda & confucius.

P. omaha ;HW band the veins dark-dusted, shading light.

P. ganda; HW band the veins not dark=dusted ;heavier dark shading.
P. ganda is normally quite oranging but it difficult to judge in fieldshots.
Male from P. Malaysia; female from Singapore.

No. 1 should be Potanthus ganda.
You can see the the respective sexes match.



2. FW with spot barely overlap spot 3 while spot 5 is detached from spot 6. FW spot 2 & 3 wider.Abdominal end with a black band.
This should be P. pseudomaesa.
