This is a lot more difficult looking at the upperside than I thought.
The extent & shape of the blue is variable in both species .
Generally T. deudorix have more blue on the HW.
This female have more HW blue than the typical T. mantra female but a bit less than the typical T. deudorix.
The definitive ID in T. deudorix, is that the underside FW is whitish near the lower margin (dorsum)
TL Seow : Cheers.
PS. Probably correct as T. deudorix, but can not be absolutely certain.
If a line is drawn across the HW from apex to mid-dorsum (inner margin) the width of the blue is twice that of the black area along this line.
In C&P4 Plate 46 fig 29 T deudorix female & fig 31 T. mantra female, the blue area is only a bit wider than the black in T. mantra. along the same imaginary line.

Reason: PS
I've just set the specimen. I'll post some photos after I take it off the board. From what I can see, it still looks like a typical T. mantra after comparing it with two other females that I bred some time back. In the meantime, this is a shot of the upperside on the setting board. Two other shots are taken from Butterflies of Thailand book comparing T. mantra and T. deudorix.
Yes, that was the first thing I checked. The area is lighter brown, although I cannot say that it is distinctly whitish as in Pisuth's book. The lighter shading at the dorsum of the underside of the forewing is something similar to what is pictured as T. mantra ogyges. Slightly lighter, but does not appear white.
