I wrote to Professor Vane-Wright about the Jamides fractilinea and J. aratus. He referred me to Drs. Andrew Rawlins and John Tennent (unfortunately he is out station and will be back next month) of NHM as both of them are working with Jamides species. I requested a photo from Nelson and sent it to A. Rawlins. Reply received from A. Rawlins and his colleagues pointed out that it is difficult to separate the two species and also male or female with only one underside photo.
I would like to amend the id as: Jamides sp (?fractilines or aratus).
