    Yes , a male Potanthus trachala .

    A combination of three features help to ID this species.

    1. FW spots 4 & 5 have no overlap with the spots above & below them, merely connected by the spikes.
    2. HW combination spots 4 & 5 forming a block is strongly projected out from the upper margin of spot 3.
    3. The abdominal end is strongly black-banded.

    Male & female.

    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.

    Female Telicota augias.

    First thing is to ID the sex.
    Female, longer profile shape, sharper apex, & abdominal end with a slight cleft.

    Eliminating the possibilities.

    Female T. colon: FW spot 4 & 5 not aligned , staggered like a stepladder (may be distorted); Face is paler.

    Female T. linna.; FW spots 4 & 5 aligned; Face & lower part of abdomen paler. HW veins not dark-dusted.

    Female T. besta. FW spots 4 & 5 aligned ; Face is paler.

    Female T. augias. :FW spots 4 & 5 aligned; More uniformly orange, face not paler.

    Confusion is very easy with poor shots & worn individuals.

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