    2. Halpe knyvetti.
    Antenna similar with a pale ring before the apiculus.
    FW upper cellspot about the same size as spot (which is triangular) in pic 2a.
    Cilia grey..

    PS. The three species in which the antennal club have a white spot below the apiculus & UnH without a white band can be Ided as follow.

    H. sikkima; FW upper cellspot smaller than spot 3 (spot in space 3) ; Underside markings illdefined; discla (interneural) spots diffuse & merging.

    3. Probably Halpe aucma.
    There is a small upper cellspot just visible.
    Key 9a. Antenna not pale-ringed.
    13a. Cell without double spot or large conjoined spot.
    13b. Termen convex.
    13 cilia chequered at least on FW.
    homolea group.
    Check out
    egena, ceylonica, & hindu.
    Check out molta.... clia white
    filda... no upper cellspot.
    Check out handa & nephele not in location.
    arcuata... cilia unchequered.

    This leaves only Halpe aucma.
    Only vague description.
    UpH darker than molta UnH markings less well-defined.

    FW cilia distinctly chequered.
    FW with upper cellspot.
    FW discal spots 2 & 3 generally with little overlap. (Huang.)
    UnH markings less defined.
    Halpe aucma. Correction:Probably an example of H. molta .FW spot 2 & 3 seem to overlap at least halfway; UnH dark spots fairly discrete.

    Huang state of H. aucma may IDed in that spot 2 & 3 have little overlap while in H. molta the two spots overlap more.
    Eliot state in H. aucma, spots tend to be small (so little overlap) & UnH markings less defined.

    Putting the two criteria together .
    H. aucma.

    This looks to be H. molta.
    Spots 2 & 3 with more overlap.
    UnH discal dark spots well-defined & discrete.

    Thanks a lot for the detailed explanation. Now I feel I have graduated in Halpe identification.

    Today, we celebrate Teachers' Day in India. So, let me wish you "Happy Teachers' Day" and thank you for all the invaluable knowledge you have imparted on us.

    While going through my Halpe collection, and cross checking with the IDs you have given, I came upon this specimen which could be H molta, which seems to have white cilia in addition to other id keys. Kindly have a look.

    4. b (same specimen as that of 4.a)

    Thanks

    Post 8.

    You are too generous with your praises.
    I appreciate the fact you brought the Halpe this time.
    I suddenly realised on going thru the species that the dozen of confusing species in the Indochinese region can be ignore.
    Two species mentioned in Evans H. kusala & flava both have UnH central band, yellow in flava & yellowish white in kusala are unlikely to occur in India.
    http://yutaka.it-n.jp/hes/91390001.html
    http://yutaka.it-n.jp/hes/91360001.html
    Correction: Both H. kusala & flava occur in NE India. (included in checklist).

    The degree of overlap between FW spot 2 & 3 in H. molta is quite variable.
    That in H. aucma should be little or almost none.
    The UnH interneural black spots are fairly well-define with the sharper margins visible.
    So it is probably H. molta.
    The white cilia is more or less the same in all three species.

    Typical H. aucma would be this.
    UnH interneural spots (Evans call these discal although the position should be postdiscal)are fuzzy & merged together.
    The ground is ?usually more golden.

    https://www.ifoundbutterflies.org/si...ae705a-2_2.jpg
    https://www.ifoundbutterflies.org/si...ae705a-1_2.jpg

    Perhaps H. molta is the more common species.

    This one with upper cellspot & well-defined HW black spots is probably H. molta.
    https://www.ifoundbutterflies.org/si...eedf1127-1.jpg

    Typical H. filda.
    https://www.ifoundbutterflies.org/si...565e6cc4-1.jpg
    https://www.ifoundbutterflies.org/si...565e6cc4-2.jpg

    It is still very difficult to ID some based on the underside alone at the moment.
    eg what should this be.
    https://www.ifoundbutterflies.org/si...4854058a-1.jpg

    What could this be.
    FW with upper cellspot;UnH black spots merged as one; central yellowish white band as in [I]H. kusala. Correction: Probably H. kusala.

    H. wantona
    Ground with the veins blacken; UnH spotswell-defined; FW cilia poorly chequered.
