The veins of this Potanthus specimen on the underside are not darkened or at most lightly darkened. There seems to be just two sub-apical spots on the forewing. I suppose P. omaha can be ruled out.
Dr Seow, any idea on its species ID?![]()

It is definitely Potanthus juno.![]()

The 3rd spot in space 8 is either reduced or totally missing.
This is more obvious on the upperside, but in this case it is a cetainty that on the upperside there will be only two spots.
This one have the veins lightly darkened & close to P. omaha, but still less dark.

Many thanks, Dr Seow for the ID.![]()
We should be able to confirm the ID with the upperside in due course.![]()

Adding two zoomed-in pics of the same Potanthus specimens to show the degree of "darkenness" of the veins crossing the yellowish orange markings on both fore- and hindwings.

This shows clearly that the veins are just very lightly darkened. In P. omaha they are strongly darkened, including the veins on the forewing as well.
Obviously a few Darts in the past have been mis-ID'd as omaha because of noticeable darkened veins.

Thanks for the voucher specimen for confirmation, Horace.Interestingly, I have two other specimens with that missing subapical spot from two other locations - Upper Seletar Reservoir Park on 11 Jul 2010 and Mt Faber Park on 17 Aug 2010.
Can you check the specimen shots that you bred from Mt Faber?![]()
I scanned through my archive of Potanthus pics and found two other similarly looking Potanthus with very small subapical spot in space 8 of the forewing.
The first one was taken on 29 Nov 2010 in WWW.

The second one was a specimen I bred (partial record) in 2007 and posted in the BC forum. The adult underside shot given in that post also showed a much reduced subapical spot in space 8 of the forewing. As a matter of fact, in that pic the adult was positioned to hide a birth defect in the other wing. Below is a shot I took of the upperside of this other wing when the butt was resting on the window.

No doubts about it.
They are all P. juno, and probably not so rare after all.
