Review.
New material available prompt a review of this difficult species.
There is a large series of set specimens taken from the Fleming collection.
The specimens were taken from Ampang Reserve (14) The Gap, Raub(1) & Fraser's Hill(1), east of K.L.
Noteworthy the male upperside is very clean with just a thin dark FW margin.
The underside is very consistent in appearance.
The side bars on the tornal black spot can also be absent.

Even with this new material we are hardly any closer to separating pura & celeno based on the undersides.
At best a suggestion to the likely species is the norm.
J. celeno typically have the HW striae more uniform in size eg.
All with UpF confirmation.

J. pura typically have the UnF outer striaes much enhanced, but this can also be seen in celeno.

The striae are best compared in the HW cell & between vein 4 & 6.
In J celeno there is a tendency to more uniformity of the striae or the postdiscal striae are slightly thicker than the cellend striae & twice thicker than the midcell striae.

In [I]J. pura[/I ]the postdiscal striae are about as thick as the submarginal striae but about twice as thick as the midcell striae.

TL Seow: Cheers.
PS. Note several ID features are no longer consistent as to be absolute.
1. Both J. pura & zebra tend to have longer sidebars on the tornal black spot, but are not consistent.
2. The dislocation of the HW white striae across vein 6 thought to be seen only for J. zebra also occur in both pura & celeno .
eg.
Male J. celeno (Ranong) shows striae dislocated across vein 6.
