    - the two outermost postdiscal striae in spaces 6 and 7 of the hindwing are slightly misaligned in the live specimen and the pinned female aratus (connected in fractilinea)

    - the two postdiscal striae in the same space as the orange tornal spot are perfectly aligned with those in the spaces above and below in the live specimen and the pinned female aratus (dislocated in fractilinea)

    Seems like it's closer to a female aratus.

    Of course my assumption that the live specimen is female might well be wrong in the first place and in any case the only fractilinea i'm comparing with is male. Also the configuration of the striae in male and female aratus is totally different (?!?!)
    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).
