I shot this Potanthus in Ubin and think it's a Detached Dart, but as S5 in the forewing is not detached, I'm not sure if I'm correct. Can you please help to ID Dr. Seow? 20160924-Detached Dart-PU.jpg
It is a vartant of P. trachala.
This is because HW spot4/5 juts out very far out from the spots below it.
Although the FW spot 5 & 6 overlaps, on the upperside it may not.
Also FW spot 4 is practically separated from spot 3 (hidden) as in P. trachala & not seen in all the other known Singapore species including P. confucius.
