    Default Help re Skippers and Arhopalas please

    Glorious hot sunny day yesterday, yet, strangely, very little about!

    Nevertheless, managed the shots attached, which I need help on ID'ing.

    1) Small skipper, I suspect an Isma species. Dr Kalesh, can you help?
    2&3) Medium sized skipper. I strongly suspect here Zela zeus optima (Orange-Ciliate Palmer) owing to the forewing spots, but would like confirmation. (Shots without and with flash)
    4) Arhopala lurida (Lesser Disc Oakblue)
    5) My best shot yet of Arhopala democritus democritus (White-dot Oakblue). I can relax now with this species as it is my keeper (at long last!)

    continue for my Arhopala problem!.....

    I previously showed the first butt as Arhopala silhetensis silhetensis, but now, I am not so sure. The second butt was shot yesterday, and could also be the same species. My problem lies primarily with the position of the postdiscal spot in space 6 in relation to the end-cell spot and the postdiscal spot in space 5. In one it is conjoined to the space 5 spot, in the other it is completely separate. There are other marking dissimilarities but less obvious.
    Can anyone help? PLEASE!

    the Zela is Z.zeus ,this genus has been revised recently so refer for the latest taxonomical status of this.
    Isma needs work up!,its difficult without an upper side shot.

    Thank you very much for confirming the Zela zeus. This confirms an earlier sighting I had last year, but I had no proof, so I was seriously considering taking it off my list.

    With regards to the Isma, I'll see what comes out with regards to the upperside, but I'm not too hopeful that it will help. I'll email you the pics, together with the Caltoris species you asked for in another thread in a few days.

    I have had confirmation from Stefan Schroder in Germany (a specialist in the Cleander group of Arhopala) that both specimens are most likely to be Arhopala silhetensis silhetensis.
