    Regarding no. 3, the veins are actually not dark-dusted. It is just the shadows of the veins. I maintain that the colour really was a bright orange in the field and not just in the photograph.

    I've included a cropped image of the other wing's stigma in post 75 to clear any doubts regarding its position and shape. Note that in C&P4, the feature of having the stigma filling the discal black striae is actually for T. hilda and not T. augias. I keep going back to the male that Soon Chye reared, since it has the confirmation of the genitalia. I have yet to find another close shot of a valid T/ augias for comparison. For T. besta, I take Horace's reared individuals as valid, since the features are all shown clearly. I believe Mr Foo has a nice T. augias upperside somewhere and I'm looking for it now.
    In C&P4 ' key T. augias is already separated from T. linna, hilda & ohara because the base of space 2 is black.

    Key 7 (12) is only used to separate hilda & linna from T. ohara which has a very narrow brand.

    Take a look at C&P4 plate 59, image 47 T. augias male & image 49 T. hilda male & look at their brand size.

    Horace also show me set specimens of T augias male & female.
    (I kept the images for comparison. The brand is straight & much closer to the outer margin of the black space.)

    Here is another example of a typical male T. augias from Jerantut, Pahang P. Malaysia.

    TL Seow: Cheers.

    PS. Whether you can really see the veins dark -dusted or not is an unreliable feature in T. besta. ( If veins are not visibly dark, it cannot be dismissed.)
    When it is really fresh it appear not dark dusted.
    There are numerous examples.

    T. colon is closely related ,the male with the same brand, & both have females which are greenish tinged UnH but hardly noticeable in field shots.
    The male also present with the UnH veins with dark dustings or none.
