Skippers ID clarification in Singapore

[Psyche]

Yes. I would say they are P. omaha.
At least the HW veins continue as dark dusted crossing the marginal zone, to the margin.
Ideally the upperside HW would be available for confirmation.
Perhaps some gene introgression (hybrid element) in the male.
The female is more obvious comparing with typical P. ganda females.
P. ganda.

Ok thanks for clarifying Dr Seow.

Apologies for adding on but two more skippers for verification please.

Could this be Erionota thrax based on the almost straight termen and acute forewing apex?

Also, is the following sufficient to ID it to Astictopterus jama?

Hi Dr Seow,

I would like to seek confirmation that the following are Pelopidas mathias?

I based it on the paler wing margins on the right individual and the general more grey-ish appearance.

Thank you.
