    Male Erionota torus.


    There are a lot of confusion with the Erionota spp.

    E. torus. FW 30/36 mm.
    FW margin strongly convexc, apex more pointed in the female.
    Antennal club 1/2 white above in female & 1/2 to 2/3 white above in the male.
    HW patch broad & more or less uniform width.
    UpF apex may have white shading.
    Male.

    E. thrax. FW 31/37 mm.
    FW apex sharper & margin straight. UpF apical margin may be lightly shaded white.
    Antennal club 1/2 white in female & 2/3 white in male.
    HW patch relatively broad throughout.

    .
    E. acroleuca apicalis

    Previously the continental population was given as E. acroleuca apex.
    Taxon apex type location Luzon is now considered as a ssp or full species & is not aplicable to the mainland population (unless the Philippine & continental forms are considered the same.)
    http://yutaka.it-n.jp/hes/92340010.html
    There does not seem to be any article treating taxon apex as a separate species.
    See PDF ,A taxonomic note on Erionota acroleuca.
    https://www.google.com/search?q=erio...hrome&ie=UTF-8

    FW sharp ,margin straight. UpF apical margin shaded white but may be brown.
    Antennal club fully white above in the male & 1/2 white in the female.
    HW with the pale patch much narrower in the upper half.
    Smaller FW 29/31 mm.

    Male.

    Female.

    Unusual form E. torus males with large white are on the club. HW patch partially narrower .Probably of hybrid origin with E. acroleuca.

    Callerebia hybrida.

    Two species have prominent ocelli in space 1b & 2 & a UnH dark discal fascia which is strongly stepped at vein 5.

    C. annanda.
    HW discal fascia more diffuse , especially in the upper part..
    HW submarginal fascia broad running into & connecting the two ocelli in space 1b & 2.

    C. hybrida.
    HW discal fascia sharper, more linear.
    HW submarginal fascia also more linear & runs short of connecting the two ocelli.

    Post 125.

    The two spwcies can be hard to judge in some cases.
    The position of the costal spot can be ambiguous.
    The text states in C. panormus the FW costal spot is adjoining the band ,meaning it is very close to it.
    The upperside colouration is also hard to judge in photos.

    Here are pictures of both.

    C. panormus male.

    C. strabo. male.

    In male C. strabo the FW submarginal chevrons are more flatten out so that the submarginal band have more level margins.
    On the HW the submarginal chevrons are all rather broad.

    In C. panormus male, the FW submarginal chevrons are strongly V-shaped.
    On the HW the submarginal chevrons are all narrower.

    From all the examples this individual is a C. strabo male . The upperside normally have darker outer streaks


    The females of both species have UnH submarginal chevrons broad.

    Thank you, sir. I had an impression that silvery veins on upperwings means C. panormus.

    The vein stripes are present in both species at certain angle & is not diagnostic.
    The text state C. panormus male is pale clear blue & in C. strabo male it is lilact (pale purplish blue).
    In photos the colour varies so much it is impossible to judge.

    I think you are right here.

    So far in India this feature is consistent.
    It would appear that the silvery veins are evident only when the butterfly is still alive.

    PS. As for post 125 it should still be C. strabo.
    Similar to this male.
    https://www.learnaboutbutterflies.co...s%20strabo.htm


    PS 2. Australia have only species, C. panormus. (+ a totally different C. amasea.)
    This is C. panormus in Australia.
