    Most likely Isma iapis.

    Two species are very similar in appearance in the field.

    Isma iapis.
    Antennal club with the underside wholly white.
    FW spot 2 (largest) quadrate in shape.
    UnF lower zone pale.

    Zographetus rama.
    This looks very similar.
    Antennal club with half the area white beneath.
    FW spot 2 irregularly elongate.
    UnF lower zone brown uniform.

    It appear these are much confused with bmany conflicting images on the web.

    The differences are so small and variation so wide it seem impossible to separate the species on the underside alone.
    Some species do have a more distinct underside eg P. philota and sumatrae.

    This would be either P. ericynoides or hewitsoni
    Since the ground is whiter and the UnF bands have squeeze the white ground band-like space into a narrow irregular band it would appear to be P. erycinoides.
    Typical P. erycinoides.

    Typical P. hewitsoni.

    This should be Dacalana vidura azyada or as upgraded to D. azyada azyada.

    The Dacalana may be IDed thus.

    D. burmana.
    Postdiscal line strongly lunulate.
    HW orange crown a narrow ring.
    https://www.gbif.org/occurrence/2847202293


    D. cremera.
    FW postdiscal line midway between the margin and the white discal band.
    https://www.gbif.org/occurrence/2847202202


    Dacalana vidura or/ azyada.
    FW postdiscal band nearer margin, gently curved to costa.
    UnH orange crown not obliterating the dark striae in space 2.
    https://www.gbif.org/occurrence/2847202242
    https://www.gbif.org/occurrence/2847202245


    Dacalana sinhara sinhara (very rare)
    FW postdiscal line nearer margin than white band, running nearly straight to costa.
    UnH orange crown obliterating most of the black striae above it.

    Zographetus kutu.

    The two species Z. ogygia and ogygiodes are impossible to separate in the field.
    The males are separated by Z. ogygia having streaks of brand on the FW, but not in Z. ogygioides.
    The females are separated ,as Eliot state mainly by guesswork.

    https://www.gbif.org/occurrence/2847175576

    https://www.gbif.org/occurrence/2847175577



    In Zographetus kut6u, the UnH is reddish brown with the spots obscure or obsolete.

    This should be correct as Rapala rhodopis.

    It is unfortunate that a large part of the HW is gone, right where most of the ID marks are.
    The remaining black spot is the one at the tornal angle, not the one in space 2.

    The saving grace is that a bit of the UpH is seen showing cupreous brown.

    Salient features.
    1. Male with UpH brownish.
    2. UpF postdiscal band straight.

    Rapala rhodopis.

    The three closest.

    1. Rapala damona. FW band curved to costa ;UpH red; UnH specked patch full sized.
    https://www.gbif.org/occurrence/2847198711
    https://www.gbif.org/occurrence/2847198711

    2. Rapala suffusa. FW band curved to costa; UpH red; Ground yellowish; UnH specked patch half sized.
    https://www.gbif.org/occurrence/2847202429
    https://www.gbif.org/occurrence/2847202434

    3. Rapala dieneces. FW band straight ; UpH red; ground more natural brown.

    Possibly as Poritia phama.

    P. phama is stated to have the FW main bands straight so that the intervening pale spacing is also fairly straight and broad.
    However this is a very variable feature.
    For example in Otsuka's Bornean Lycaenidae (available for download) P. phama have narrow crooked bands and P. hewitsoni have straight broad bands, the reverse of what the key states.
    The IDs there was based on the upperside.

    Furthermore Saito and Seki in a revision in 2006 considered phama and hewitsoni the same species and phama falls as a junior synonym.
    This is followed by Yutaka.
    The taxa regia and rajata formerly as ssp. of P. phama are now under P. hewitsoni.
    https://yutaka.it-n.jp/lyc1/80060020.html

    I leave this as P. phama.
    Perhaps some will do a molecular analysis.

    Try to get an upperside.
    It will give some clue of what it really is.

    Female Pithauria stramineipennis.

    This resembles a Halpe but is very large with long FWs.
    The underside pattern is very variable, often with vague interneural spots & antennae are orange-tied.
    Only the male have the straw-coloured hairs.
