Dear Sir,
Thanks for your valued response. In this context, I would like to say YES, both species exact identification is some difficulty. I have checked all the type specimens and have seen there all lots of variation (especially for Jamides caeruleus). Butterflies of Malay Peninsula, Part I also mentioned for Jamides caeruleus - UnH with the 2nd stria from the base in space 7 in line with the 3rd stria from the base in the cell OR at least nearer to this stria than the second cell stria (exactly matched with my specimen)as like your comments. FW Post discal band also dislocated at vein 3. You are requested to recheck my specimen. For your information, Jamides caeruleus also recorded adjacent locations from my site. Indian most experts also go with Jamides caeruleus for it.

Regards,
Rajib Dey
