2. While I have found a few Potanthus shots of mine that have a large HW spot 6, the FW spots 4 and 5 aren't broadly overlapping with the adjacent spots as seen here but I'm not too sure.

Will be looking out for more photos once I'm done with class! Thank you so much in advance!
I agreed both should be Potanthus omaha as the HW veins are fairly dark dusted.
The 1st pic is exceptional for the wide overlap of the FW spots & the very large HW spot 6.
Still I would like to introduce a species very similar to P. confucius, a bit larger.
There is a possibility this could find its way to Singapore.
Potanthus pava. FW 15mm.
Abdominal end yellow with basal black line/narrow band.
FW band continuous as in P. confucius Overlap may varies.Male may have the base of space 2 yellow shaded (as in T. colon or besta)
HW with a prominent spot 5 in both sexes usually large espceially on the underside. Underside bands edged in black streaks, not spots. http://yutaka.it-n.jp/hes/92820001.html
