Either E. doubledayi or eyndhovii. Probably E. doubledayi.
It is near impossible to separate the two species based on the underside markings.
E. doubledayi is distinctly larger, being slightly larger than E. mulciber.


E. doubledayi larger FW 50-55 mm.
Male UpF with a dark blue sheen. Female UpF with some discal spots.

eyndhovii. Smaller, FW 45-55 mm.
Male UpF dark velvety brown; Female UpF unmarked.
UnH more often with larger white discal spots.

Probably correct as Notocrypta clavata.
In this species the UnF white band run to the costal margin broadly, & FW spot 4 is rarely present.
Here the UnF white band seem to taper slightly at the margin, but variation occurs.

There appear to be two species & perhaps several individuals.

Pix 2, 3, 4, 5, & 6 appear to be Euploea doubledayi .(Probably E. doubledayi occur in Penang after all.)

The 2nd pic here shows a narrow brand & the HW with longer stripe-like spots.
The dull blue-black FW sheen indicate it should be E. doubledayii.
The UpF of E. eyndhovii is dark brown.

Pix 1, 7, 8, 9, 10, & 11.should be Euploea algea.
The HW submarginal spots are shorter bars, longest at the tornus & tapers upwards.
The upperside have a deep dark blue brilliance.
https://yutaka.it-n.jp/dan/30600010.html
The male brand is broad & long.

Other similar species have the HW submarginal spots more uniform in size.

Dr Seow, Thanks for all the detailed ids. Appreciate it

For #1 Euploea, I believe all the photos are of the same butterfly which I spotted outside a shopping mall - where four of these ficus-looking trees (I dont know how to id tree) are planted. The butterfly would fly off and then land on another part of the tree or another tree when I approached too close. All photos were still shots of videos that I took - all within 10 minutes.I did not see another Euploea or other butterfly when I was there that I am aware of.

I am afraid there have to be two species.
You cannot reconcile the underside shot of Pic 1 with the upperside shot of Pic 3.
The shape of the HW submarginal spots are too different.

The thin male brand on the FW is that of eyndhovii/doubledayi.
eg E. eyndhovii.

Thanks again Dr Seow for all the ids. Noted your feedback on the #1 photos. I will review the photos closely and go through my videos. Perhaps go back to site location. Cheers from Penang, SLL Liew
