    Default Isma sp. for identification

    Dear Dr. Seow sir,

    I am here again with some Isma sp. that needs species identification. Is there any possibility of Isma bonota or they are different.

    Thank you in advance.

    3 & 4 are Isma bonota.
    https://www.ifoundbutterflies.org/#!...01/Isma-bonota

    1a & 2 are variants of I. bonota in which UnH have 4 spots. Correction: Males.

    1b is Zographetus ogygia.
    FW cell upper one much smaller than lower one
    Likewise subapical spot 6 is much smaller (may be absent).
    Antennal club with larger white area.

    FW upper celspot large (combined with the lower one in female).
    FW subapical spots 5 & 6 subequal.
    Antennal club white area smaller.

    TL Seow: Cheers.

    PS. 1a & 2 possibly a different Isma species, but only one Isma species known in India. Correction: only one species.

    PS 2. 1a & 2 are likely males & 3 & 4 are females.
    In all known Isma species the HW spots in the female are smaller & separate.
    Examples.
