Hesperiidae ID Request - Singapore

[loomins_zoomins]

Dear Dr Seow,

My name is Lumin Ong and I'm a new member here! May I request ID for the following Skippers:

1. Pelopidas sp. from Pulau Ubin? The forewings on this individual are longer than what I see usually in a P.mathias!

2. Potanthus sp. May I also ask what does it mean by black-dusted veins? Sometimes I see that the "dust" is under the vein.
