Skippers ID clarification in Singapore

[sabafish]

Hi Dr Seow,

Here with a new set of skippers from a friend. I am trying my hand at ID-ing them, so would appreciate your assistance to confirm or correct my preliminary IDs.

Thank you!


1. Pelopidas mathias? Ground colour looks unevenly shaded.

2. Pelopidas agna? This on the other hand looks pretty even.

3a. Caltoris cormasa?

3b. Caltoris cormasa?

3c. Caltoris cormasa?

3d. Pale region of the antenna made me think Caltoris, so perhapsCaltoris cormasa?

3e. Caltoris cormasa?

3f. Caltoris cormasa?

279114685_441400837632940_808999942510470927_n-2.jpg

4. No pale region on antennae, more ochreous UNH so could be C. malaya?

1 is undoubtedly Pelopidas mathias.


2 is too worn, perhaps correct as P. agna.


P. mathias Darker, greyer ,unevenly shaded; FW cilia darker.

3a Likely Caltoris malaya male.

The pale area on the antenna is prominent in C. cormasa, bromus & cahira, but less so in C. malaya, & even less so in C. philippina.
However the feature may be variable dependant of the flash or shot angle.

Here the FW is raised high enough to show no upper cellspot.


C. malaya. No cellspot Underside rusty brown in male, more ochreous in female.
All Singapore examples.

TL Seow: Cheers.

Thanks Dr Seow!

Adding on 2 more skippers for ID.

1. I am thinking Baoris? FW cellspots seemed to be equally sized but subapical and discal spots are not reduced? Hence I am stuck.

2. Telicota sp. but unable to go further. Perhaps T. besta?
