    Default Request for ID help and Verification from Assam

    Dear Dr. Seow sir, I hope you are good and healthy as always. I have tried to identify some of the moth species available in our area and would like to have your views on it. Kindly provide the id keys of the species (under the identified genus) if possible.

    Regards
    Atanu Bora

    Cheers

    Thank you for your concerns. I am fine.
    Now moths I haven't done for quite a while .
    with thousands of species it will take time.
    I get all my sources from the web with frequent cross- checkingn now easier with the help of GBIFie.
    Global Biodiversity Informations Facility.

    Achelura bifasciata is right.

    A. bifasciata TL. Assam
    Antemedial & postmedial bands parallel ie equal distance apart.
    Antemedial may twice as broad as postmedial
    More yellowish orange.
    Distal wings whiter.
    Typical.

    Two other similar species nearby.

    A. yunnanensis.
    Fascia deeper orange ,more nearly equal.
    Postmedial orange fascia more bend outwards in the lower half so that at rest the distance is greatest in the midline between the two fasciae.

    A. myamyoana
    This third species is found south in Myanmar to north Thailand.
    The antemedial is very much broader still ,& the wings darker.

    Macroglossum troglodytus.
    Note the very curved antemedial fascia (band)a triangular subapical costal patch joined by an L-shaped black bar to the outer margin.

    Correction Most likely Episteme maculatrix.

    Below description based mis- identifed images.
    Episteme nipalensis.
    Antemedial & postmedial spots of similar proportions.
    Postmedial spots without darkened veins.
    HW bright orange/red.
    Abdomen broadly banded black.
    https://www.gbif.org/occurrence/899969044
    Same observation as IDed by hkmoths, Dr R. Kendrick.
    https://www.inaturalist.org/observations/627384
    https://www.gbif.org/occurrence/2244221940
    https://www.gbif.org/occurrence/4111617558


    Similar but confused with it.
    Episteme maculatrix.
    FW with the postmedial spots divided by black veins.
    Abdomen shaded blackish dorsally.

    https://www.mothsofindia.org/Episteme-maculatrix
    https://www.mothsofindia.org/episteme-maculatrix

    Possibly these below may be examples of E. maculatrix different ssp.
    FW only the costal postmedial spot with the veins black.
    Abdomen with narrower black bandings.
    https://www.mothsofindia.org/episteme-nipalensis
    GBIF have no examples of these as E. nipalensis.

    E. vetula.
    FW postmedial & antemedial generally narrow & as yellow bands.

    Margina argus.

    Similar.
