Hi Dr Seow,

Require some help with these skippers. Thank you!

1. Caltoris sp. There are two FW apical spots, C. malaya?

The picture uploaded here might not be clear, so here's the iNaturalist link for better details:

2. Caltoris sp. The FW spots seem different from a typical C. cormasa, maybe C. bromus?

3. Is this Caltoris or Polytremis?

4. Potanthus omaha?

Thank you Dr Seow, based on your explanations, number 3 should also be a Caltoris malaya with the more ochreous shaded brown and two FW subapical spots? A little unclear with your numbering hahaha

3 is Polytremis lubricans male.
Look at the markings on the antennal club. It is different from Caltoris.
HW spots on the underside may be invisible.
