Could this be a Deudorix staudingeri? Shot in 2006 at TBHP.

The HW orange spot is not surrounded in black.

Yes. This is a male Deudorix staudingeri.

The dark striae are prominent & the white striae somewhat faded.
The orange ring is more rounded, & not outlined in black.


In contrast, in D. epijarbas, the white striae are strong, the dark striae weak, the orange ring is more rectangular. It may or may not be edged darker.
Three males of D. epijarbas for comparison.

This observation from USR Oct 2006 is also D. staudingeri.

Many thanks, Dr Seow for the ID confirmation. :):gbounce:

Dear Doctor Seow,

I have shot a Deudorix from USR as well, would this be a D. staudingeri or D. epijarbas? The specimen is a bit faded, and harder to ID

Post 6.
The white atriae in D. epijarbas is typically very strong.
If both white & dark striae orf the FW band are equally faded as here it is D. epijarbas.

In contrast in D. staudingeri, the FW band's white striae fades off or become sullied, the dark striae are prominent.
