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.

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.

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.

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