    It is definitely Baoris male, likely Baoris oceia.

    The separation of B. oceia & farri is etremely difficult.
    It is simply assumed in the past the dark ones are oceia & the lighter brown ones are farri.
    B. oceia also tend to have reduced spots but all Singaporean examples of males have reduced spots.
    these presumptions are unscientific.

    B. oceia does not occur further north in Indochina or India.
    Thus examples there can be certain to be B. farri.

    From the observations, B. farri have the HW cilia always pale, the FW cilia may be darkish.


    Probable examples from Singapore.

    It seem easier to separate the females.
    It may be all current photos of males are of B. oceia.


    TL Seow: Cheers.
    PS. It is possible there are no valid shots of B. farri, male or female from Singapore.

    Yes. This looks correct for Telicota linna male.

    Fieldshot I are difficult.
    Here is a reiteration of the ID features between T. linna & besta.

    Telicota linna male.
    1. HW veins usually not raised or darken.
    2. HW ground colour duskier.
    3. Thorax hairs darker/duskier than the wing colour.
    4.Face & underpart (abdomen ) generally paler.
    5. Upperside male brand in middle of black space & base of space 2 black.

    Males.

    Telicota besta male.
    1. HW veins raised with shadowlines or slight dark dusting.
    2. HW ground colour clearer ,tawny or orange.
    3. Thoracic hairs orangey, closer to HW colour.
    4. Only face is slightly paler.
    5. Upperside male brand arcuate, nearer inner border & base of space 2 with an orange patch.

    Males.

    Telicota augias is often confused with T. besta.
    Often T. besta is misIDed as T. augias.
    Here is an unusual instance of T. augias misIDed as T. besta.
    Note T. augias male brand broad, straight in the middle of black space, & base of space 2 with an orange patch (as in T. besta).

    1. Male Baoris oceia. Pale area on the antenna (seen here) more often not visible.
    Baoris oceia male often have reduced spots. eg especially the subapical spots.
    In Singapore, the upper cellspot is lunulate(crescent) as seen here.
    Hw may have a vgue pale patch at the cellend.

    Caltoris philippina is very different, being narrow-winged.
