A recent observation strongly suggest the presence of Potanthus pava in Singapore.
Potanthus pava. FW 15mm vs FW 12-13 mm in P. confucius.
Abdominal end yellow with a narrow black band basally.
FW band yellow broad or relatively narrow, veins not blackened.
In the broad band form the band appears continuous & uninterrupted as in P. confucius.
Male FW base of space 2 with yellow scalings.
First pointed out by a Japanese entomologist, this is practically diagnostic as it does seem to be present in any other species.
Underside band edged with black streaks, not spots.
HW spot 6 prominent, large especially on the underside.

In this recent observation note the following features.
1. FW base of space 2 with yellow scales. Also seen on right UnF as a small triangular patch.
2. FW band with veins not blackened.
3. HW with a large spot 6.
4. Abdominal end yellow.

This observation seem an almost certainty(99%) to be Potanthus pava.
TL Seow: Cheers.
PS. It is highly possible this observation is also P. pava but without an upperside it is difficult to prove it.
