    Default Doubtful IDs from Nepal

    Ok, I'm starting a new thread for my doubtful species from Nepal rather than creating many threads for each species. To start with, I had seen several of these Halpe back in April, central Nepal, what I think is H. arcuata. Again, it's not reported from Nepal and has been reported from as far as Assam in the far east. The only other recorded Halpe without FW cellspot here is Halpe filda.

    It is probably Halpe filda.
    Definitely not H. arcuata.


    H. arcuata.
    FW spots 2 & 3 wide & almost fully overlapping.
    FW without cellspot.
    Subapical spots 2.

    Halpe filda.
    FW almost always without a cellspot.
    Subapical spots 2 or 3.
    FW spots 2 & 3 with only partial overlap.


    Two others formerly included under H. homolea, H. aucma & molta have a prominent FW cellspot.

    All three , H. fllda, aucma & molta can be seen in the link below ,Colour Plate 1.

    Thank you, Dr. Seow. Could you check on this Ypthima baldus as well? I don't see the characteristic striae on HW well like on my other individuals. Is there any other possibility?

    It does look s correct fot Ypthima baldus.

    In this species the ground colour of the outer half of the wings are paler ,so the fasciae contrast more. ie the submarginal fasciae (bands) are very distinct.

    The next closest Five-ring is Y. persimilis.
    The ground colour is not much paler & the submarginal fasciae contrast poorly.

    This individual has overlapped FW spots, found on the same location though.

    Halpe arcuata

    FW spots 2 & 3 are wide & broadly overlapping.
    A small FW cellspot may sometimes be present as seen here.
