Post 4.

Yes, a female Caltoris cormasa.

This species have a redder tone to the UnH brown in photos. FW spots are yellowish.

The UpF shows a single cellspot ,which is stated to be usual, thus called the Fullstop Swift for the single spot.
However, many Singapore examples often have a second tiny upper cellspot.

Male have a rounder FW apex. Female a more pointy apex & a longer profile.
Two males , one female.

Thanks, Dr Seow!

Confusion is very easy with poor shots & worn individuals.

Here is another that should be correct as a female T. augias.
