    Female likely P. omaha.
    The veins on the HW band are just lightly dark, but more so on the underside pic 6.
    UnH ground dark-shaded, no dark spot.


    A third species with a yellw abdominal end may be confused hre.

    Potanthus confucius.

    Abdominal end yellow.
    Veins across band not dark-dusted, including on the FW
    This cause the FW band to appear continuous & unbroken in the male.

    There is a suggestion that several individuals are present ie upperside images 2, 10, 7 12 do not seem matching, there appear to be one species only.

    Underside images 1, 4, 7, 9, & 11 have the following features.
    FW band/line is oblique. This indicate there should be fine black dots, which are not visible.
    All shows a consistent features.
    Hw postdiscal spots 6 & 7 are in line, while submarginal spots 6 & 7 are out of line/dislocated.
    These features are that of Curetis santana.
    Curetis santana.

    13 & 14 are probably variants of one species.
    The legs are banded orange.
    The ground is marked with black dots.
    In 13 the fW band is parallel to the outer margin.
    In 14, the FW band is bent so that it is more or less parallel to margin, ie no longer oblique.
    HW postdiscal spot 6 is tucked under & inwards of spot 7.

    They both match the criteria for Curetis sperthis.
    https://yutaka.it-n.jp/lyc3/84070001.html
    Perhaps 14 has a hybrid element to it.

    Eurema andersonii
    There is only one cellspot & the inclination of the FW black border in space 2, 3 is as for andersoni.
    Just that the markings are heavy.


    16.https://www.inaturalist.org/observations/251010058
    Too dificult & vague. Most likely Isma iapis.



    17.https://www.inaturalist.org/observations/251010052
    Most likely Isma iapis.

    The FW cellspots, upper small & lower elongate is seen in many Isma ssp (variable feature).
    FW spot 2 is quadrate; there is no spot in space 1b, & the HW does not seem to have hyaline spots.
    There appearance is that of Isma iapis or protoclea.
    https://yutaka.it-n.jp/hes/91880001.html
    https://yutaka.it-n.jp/hes/91890020.html

    In this shot the underside can just be made out as greenish ochreous with obscure spots.
    https://inaturalist-open-data.s3.ama.../original.jpeg
    This w2ould be as in Isma iapis
    https://thaibutterflies.com/Butterflies/isma-iapis/
    In I. protoclea UnH is purple brown & rather dark.
    https://wingscales.com/Hesperiidae/I...toclea-obscura

    This shot in which the FW have two large cellspots is of another species.
    https://inaturalist-open-data.s3.ama...354/large.jpeg
    Could be these.

    Probably Eurema brigitta (drona).Uncertain.

    This is just too vague. The HW hides the FW cellspots.
    Hw spot 7 is almost touching the FW cellend spots/marks.

    This cannot happen in E. nicevillei as thet are far apart.
    https://wingscales.com/Pieridae/Eure...lei-nicevillei

    E. sari & simulatrix have prominent brown patches on FW apex.
    E. andersoni have a tailed Hw spot 7

    E. hecabe have angular HW & E. blanda have a curved hW spot 7.
    E. hecabe.
    https://inaturalist-open-data.s3.ama...4962/large.jpg
    https://thaibutterflies.com/wp-conte...a-hecabe-3.jpg
    E. blanda.
    https://www.butterflycircle.com/chec...an-Ben-JIn.jpg
    https://www.ifoundbutterflies.org/si...431_261668.jpg

    This leaves E. brigitta (=drona)
    Often with reduced vague markings ;FW cellend makr twin spots.
    https://yutaka.it-n.jp/pie/21200020.html
    https://www.ifoundbutterflies.org/si...397b5571-1.jpg

    Pemara (Oerane) pugnans.

    Note downturned antennae; FW subapical spots 7 & 8 smudged black.
    yellow spots.
    https://www.butterflycircle.com/chec...20-%20Khew.jpg


    20.https://www.inaturalist.org/observations/248154315
    Female Potanthus serina.
    Note black abdominal end
    FW spot 5 smaller than spot 4.
    HW band with a smaller inner spot 6.
    Male & female.
    https://thaibutterflies.com/wp-conte...hus-serina.jpg

    Both look the same.
    22 is Isma iapis & 21 should be too.

    The underside of Isma iapis is a pale greyish ochreous.

    23.https://www.inaturalist.org/observations/246316620
    Cephrenes trichopepla.
    The nipple-like spot on top of 6the HW orange band is diagnostic.


    24.https://www.inaturalist.org/observations/243065121
    Neptis leucoporos.
    On FW lower margin larger spot is at the top. the lower small spot may be obscure.
    A white band across the abdomen if visible is diagnostic.
    https://blogger.googleusercontent.co...erick_01_c.jpg

    In N. duryodana the smaller spot is at the top at the FW lower margin.
    No white band across the abdomen.

    25.https://www.inaturalist.org/observations/243065114
    note hW completely smooth margin.
    Amphimuta group.
    Small member of a different subgroup eg A. zylda , A. muta,etc.



    26.https://www.inaturalist.org/observations/241095332
    Oriens paragola.
