Here are three specimens which I have in my J. malaccanus file. However, there are breaks in the markings, which suggest I may have one or more wrong.

They are in increasing order of broken striae.

These are difficult ones to ID.
There are 2 similar species malaccanus & parasaturatus.

1 & 2 should be J. malaccanus male & female.
3 have the striae more misaligned but topside exposes space 4, 5, & 6 of the right hindwing.The large & dark inner & outer submarginal spots is more in accord with J. malaccanus.
I would leave them as J. malaccanus.

There are many errors on the net eg. Wilkipedia have the correct male malaccanus but the female is a member of the elpis subgroup.

Thanks, Seow. It was specimen 3, photographed today, that got me a bit concerned. I also have a photo of a specimen from Nakhon Sri Thammarat province which has all the striae absolutely perfectly in line, so I did start to wonder.

I found the confirmation for pic 3.
C&P4 states in its key that the female of malaccanus have the veins lightly dark dusted in the distal third of the wing.
A check with the images in C&P4 and Fleming indeed shows that in malaccanus the veins are distinctly darkened between the marginal & submarginal spots whereas in parasaturatus they are much less so.

In pic 3 the topside veins visible are vein 5 & 6 , and they are strongly black whereas in parasaturatus they would only be slightly darkened.

We can conclude that pic 3 is indeed a female J. malaccanus.

I have located the correct upperside/underside images of the males of malaccanus & parasaturatus for future reference.
http://www.boldsystems.org/views/taxbrowser.php?taxid=296319

The one on the left with the broken right forewing is malaccanus.
ID points ; deeper blue; dark border along termen; hindwing with dark 'spots especially near tornus.

The one on the right is parasaturatus.
ID points ; lighter blue; dark border towards apex; hindwing without the dark 'spots'.

Just one definite parasaturatus have beeb found on the net.
This is Federick's shot from the Panti forest, Johor.

Note the differences. (Topside pale blue visible.)
1. Submarginal striae on forewing becoming obsolete towards the apex. (Evenly defined throughout in malaccanus.)
2. Striae blue-tinged due to translucency effect , ie. Glassy Caerulean.( Hindwing striae strongly white in malaccanus.)

This is a Malayan example of malaccanus for comparison.
