Hi to all
Internet newbie here , so pardon me if I do not try to paste the quotes.

Les,
As far as I know there are only three endemic Tanaecia in Borneo, and only two are in the T. pelea group. T he other T. amisa is white-banded.

Lc.
Discophora necho is the only blue-banded duffer.

Les,

Picture of the third Tanaecia lutala can be seen at kielo.luomus.fi
Sorry, I dont know how to put in the link.

Hi TL, I could not access the page for some reason. However, I have found out that I did photograph this other reversed fleche specimen. As you can see, the hindwing markings are much reduced.

Les,
This should be the male. Typically in the pelea group, the sagittate markings on the hindwing are short and somewhat detached in the male, while in the female it tends to be joined into a zigzag.
If you made a search for Tanaecia lutala, the website is at the bottom of page 1, some Finnish museum or university. Anyway T. lutala have the normal orientation.

Thanks very much. I had thought it might have been male and female, but wanted to be sure.

Les,

I was confused when I saw that T. lutala is a member of the pelea group ( somewhat like T. aruna ). On checking,I realised that someone have upgraded many of the insular races into full species. Borneo's pelea and aruna have been replaced by T. valmikis and T. lutala. By the old reckoning, there are only two endemics, T. amisa and T. orphne. Iniatially I was unsure whether there were any new discovery that might resembles T. orphne, but now I am certain that there are none.

Yes, T. valmikis was one of the 'species' I had found listed. There is still another one, T. elone. I got these names from the funet.fi website (another Finnish University site).

T. elone, probably endemic to Sumatra only, have as stated in C&P4, a blue-shaded white band on the hindwing.

Hi TL, I could not access the page for some reason. However, I have found out that I did photograph this other reversed fleche specimen. As you can see, the hindwing markings are much reduced.

After much sleuthing, i realised that this is in fact female Tanaecia iapis ambalika f. ambalika(the other, f. magnolia resembles the male; some classifications recognise cocytina as a distinct species and place this as T. cocytina ambalika instead)). It matches the figure in D'abrera perfectly. It is the only subspecies of iapis/cocytina, strangely, to have the sagittate markings pointing outwards away from the base of the wings. Probably the only Tanaecia to have this arrangement.

True T. orphne has the sagittate markings in the "normal" orientation. Female orphne resembles T. aruna but the spots in spacs 2 and 3 on the forewing are more rounded(C&P4). Male orphne is very distinctive.

This probably is the only correct image of female orphne.

The other photo, in which the sagittate markings are reversed as well but the butterfly appears whiter is either a variant or another form of iapis ambalika or one of the numerous other subspecies of iapis found on Borneo which i don't know. (Unless someone has a copy of Seitz' Macroleps at hand right now)
