Hi,
I believe I also saw one today. DSC04708.JPG. Am I right?

Oh. The forewing band looks very different from yours. Spots are very small.
Does anyone else have an opinion on the ID of this aberrant looking trogon?
thanks for advice,
yik
Yik's shot does not seem to have the purple wash that A. trogon normally has.
Oops here. It is A. trogon.
I have actually thought it was A. trogon much earlier when comparing the spots but got sidetracked with the purple wash feature later.
You raised a very pertinent point here.
Note without the flash the underside is quite purplebrown.
An important clue to the ID of A. trogon is that the two black spots in space 1a(tornal angle) & space 2 are quite large.
In A. aurea they are somewhat flattened.
The male A. aurea is also slightly purple-shaded, but without the strong glaze very apparent with flash in trogon.

Apart from the more prominent black spots the markings of A. trogon tend to be broader.

Thanks Dr Seow. Now that you mentioned it, the relative prominence of the black spots suddenly becomes quite obvious!

This cannot be trogon. I'm very certain this should be Arhopala corinda. The whitish area at the fw dorsum and the strongly contrasting basal dark scaling are diagnostic (in trogon the dark scales are not so apparent).
This specimen is slightly aberrant but still the spots forming the post-discal band on the forewing and spots 6 and 7 on the hindwing are distinctive because they are more rounded than in pretty much all examples of aurea and trogon. In particular, spots 6 and 7 on the hindwing are much larger and rounder than the one in space 5 (the shape difference is quite noticeable). In aurea and trogon there is no discernible shape difference between these spots and they are always very rectangular.
There are also subtle differences in wing shape that rule out aurea/trogon.
I'd be glad if someone with C&P4 at hand can verify this

I think you got it right here.
The markings are as for A. corinda.
My main concern is that the marginal spot in space 2 is large & rounded much as in A. trogon, whereas in A. corinda it tends to be somewhat flattened.
TL Seow: Cheers.
