    Lightbulb Arhopala ID trend

    Hi Doctor Seow,

    I have had the chance to see a good couple of arhopala over the last few months, but i do not quite understand how to ID arhopalas well enough, so i decided to slot all of these here to consolidate the arhopala IDs here. I cant even narrow to which subgroup currently as well.

    from Singapore

    1 - arhopala sp
    inat observation link - https://www.inaturalist.org/observations/156201179

    from Malaysia, Panti forest

    2- arhopala species

    5. Arhopala antimuta.

    Tailless species with HW spot equal between spot 5 & cellend bar.

    7 Probably A amphimuta.

    8. Alea subgroup member possibly A. sublustris. costa spot 9 more shiftedin.
    https://www.inaturalist.org/observations/180465037

    9. Probably A. amphimuta.


    10 Probably A. amphimuta.



    A. amphimuta have a better formed "V". The fout postdiscal spots above the "V" are also in line .

    A. amphimuta.

    Many exceptions eg

    Arhopala major.
    V spot distorted & postdiscal band broken.

    Hi Doctor Seow,

    A couple of arhopalas which im quite unfamiliar with shot in a short day trip in Malaysia, hope to learn more from your insights.

    1 - https://www.inaturalist.org/observations/202971454

    2 - https://www.inaturalist.org/observations/202971462
    major subgroup - most likely Arhopala major but since this is shot in malaysia i would like to be more cautious

    3 - https://www.inaturalist.org/observations/202971473
    Same reasoning as above, i believe this is A.major

    4 - https://www.inaturalist.org/observations/202972571
    Arhopala muta or that subgroup?

    5 - https://www.inaturalist.org/observations/202972589
    initially looks like major subgroup, but im not too sure

    6 - https://www.inaturalist.org/observations/202972590
    Looks like amphimuta

    7 - https://www.inaturalist.org/observations/202972592
    HW slightly torn, not sure if its still identifiable

    8 - https://www.inaturalist.org/observations/202972594
    same as above

    Post 7.

    1 https://www.inaturalist.org/observations/202971454

    Very likely Arhopala aroa.
    Salient features.
    Member of the alea subgroup.
    FW margin very rounded.
    HW with dark purple right to the margin.
    abdominal end & short palpi also indicate a male.

    Only two species in the alea subgroup have the FW rounded in the male.
    It is less obvious in A. selta which also have a broad HW border & a blocky HW spot 6.
    https://yutaka.it-n.jp/lyc4f/82110001.html
    https://thaibutterflies.com/Butterflies/arhopala-selta/

    Arhopala aroa have more rounded FW, dark purple blue to the HW margin & a Hw spot6 which is wider above & convex on the outside.

    See also Otsuka L 211.

    Amphimuta group.
    Tailless. HW postdiscal spots arrange in an arc crossing the gap between spot 5 & the cellend bar.
    MUTA.png
    Amphimuta aubgroup.
    Medium large FW 22mm [HW spots widely separated from the cellend bar.
    eg. A amphimuta, major, norda & moolaiana.

    A. amphimuta Hw V spot wellformed &postdiscal band mostly not dislocated.
    https://4.bp.blogspot.com/-J9Xmngyim...+amphimuta.jpg
    https://blogger.googleusercontent.co...a_Simon_01.jpg

    A. major hW V spot distorted & postdiscal band dislocated.
    https://blogger.googleusercontent.co...en_wing_01.gif
    https://blogger.googleusercontent.co...ederick_01.jpg

    A. norda (narrower markings) & moolaiana( broad markings) both have a HW tornal white spot.
    https://thaibutterflies.com/wp-conte...pala-norda.jpg
    https://thaibutterflies.com/wp-conte...-moolaiana.jpg


    The other smaller species belong to several subgroups.
    They have the HW postdiscal spot 6 larger & placed closer to the cellend bar.
    except for A. kurzi all are nearly unidentifiable from the underside alone.

    A. muta/moorei have UnF spot 2 & 3 out of line (hidden).

    A. kurzi have the V spot ( split here) widely separated from the postdiscal band.

    5.https://www.inaturalist.org/observations/202972589
    6.https://www.inaturalist.org/observations/202972590

    2, 5, & 6 A.maajor.

    3. https://www.inaturalist.org/observations/202971473
    4.https://www.inaturalist.org/observations/202972571
    Unknown.

    7. https://www.inaturalist.org/observations/202972592
    8. https://www.inaturalist.org/observations/202972594

    7& 8 looks to be the same species...unknown.


    TL Seow: Cheers.

    PS. The differences between A. amphimuta & major as stated above are more as in Singapore.
    In P. Malaysia they may be nearly inseparable.
