    Default Id request for lineblues

    Requesting id for these lineblues. All photos taken from NE India. For most of my Prosotas and six lineblues, I am able to ID, thanks to the discussions on this forum.

    5. Prosotas nora ardates. (The submarginal spots are actually stronger than the marginal spots).

    Prosotas nora.
    Underside submarginal spots typically well formed & of the same or greater intensity as the marginal spots.
    UnF with the mid cell band continue full width into space 1b; likewise the postdiscal band is continued into space 1b.
    Note all examples below have the extension of the postdiscal band & mid cell band visible in space 1b.

    Prosotas pia
    Similar to P. nora. . Midcell band extension into space 1b may be weak or even absent , but the postdiscal band have a spot in space 1b always.
    Submarginal spots (lunules) weak, obsolete or faded compared to the marginal spots especially on the HW.
    P. pia pia Borneo. Note the extension of midcell band into space 1b is much reduced.

    P. pia marginata Thailand.
    Female.

    P. Malaysia.ssp pia.
    https://2.bp.blogspot.com/_0EK80AsaR...sotas+nora.jpg
    Example with the midcell band not extending down into space 1b. (Sulawesi)
    https://www.floridamuseum.ufl.edu/wp...ily_plate6.jpg

    P. bhutea.
    Easily confused with P. pia in having the submarginal spots blurry.
    UnF space 1b absent of spots from the postdiscal band & the mid cell band.Diagnostic but not visible when the FW is down.
    UnF postdiscal band composed of spots with more rounded sides, & often dislocated at vein 6. . Postdiscal band is always dislocated at vein 3 in all species.

    All examples below with space 1b visible.
    In field shots the FW postdiscal band's more rounded & dislocated spots is the only clue with the FW low.

    Thank you very much sir. Now things are more clear for the Prosotas.

    As for fourlines, I will have to get new photos and try checking myself the ID keys you have given.

    Just one thing, the specimen 4 is a sixline (not fourline). If you could just have a look and tell me the species. As for the id keys, I have already taken down from another discussion, but just because of the faded nature of the specimen, i am unable to pin point the species.

    Warm regards
    Aomoa

    Oops! I simply assumed you have put in only 4 line blues since you said you have the 6 lines IDed.
    The markings are faint here.

    4. Nacaduba berenice.
    FW with a costal spot above the innermost mid cell band.
    Dark striae within the bands typically strong.
    FW submarginal are irregular.
    FW postdiscal band often with a mid dislocation.
    Examples.
