Tajuria deudorix is one of many duplex species which is as usual almost identical on the underside with its sibling species, in this case Tajuria mantra.

T. deudorix's life-history was in fact recorded during WWII in Singapore.
So it would seem strange if it disappeared without a trace.

The main ID clues are on the upperside.
However, the underside does show very minor differences.

1. There is a tendency for the FW to be more rounded than in mantra (not reliable.).

2. The diffuse submarginal fascia is midway between the termen & the postdiscal line.(Probably only in the male.)
This diffuse fascia is alway nearer the wing margin in T. mantra.

3. The teeth formed by the HW postdiscal line are not so sharp.
a. The parts of the line in space 2 & 3 are straighter. (Strongly curved in lower portion in mantra.)
b. The part in space 1b, a chevron or broad V have more or less two equal arms.
In T. mantra this chevron has the upper arm longer.

The appearrance in T. deudorix is more like a series of steps vs. jagged recurved teeth in T. mantra.

In this example of T. deudorix from Palawan (different ssp.) note points 2 & 3.

I had long suspected some of the specimens labelled mantra to actually be deudorix solely because some specimens appeared to have the post-discal line nearer the termen than usual but I wasn't sure of how else to distinguish them based on the undersides alone. Like most Iolaini, the differences are mostly on the dorsal surface.

Interesting that the underside of the Palawan specimen of deudorix looks more like the Sulawesi species cyrillus.

The Palawan subspecies is Tajuria deudorix yuhkichii.
It does have some similarity to T. cyrillus (below) but not quite.

It is notable that the difference in the degree of serration of the HW postdiscal line also holds true for both the subspecies of T. mantra & T. deudorix in the Phillipine proper.

This nss shot is without a shadow of doubt a female Tajuria deudorix ingeni.

In the female the FW postdiscal band may be shifted a bit further in so that the diffuse submarginal fascia is no longer midway between it and the termen.
The HW postdiscal line is typcal T. deudorix.
