no 9. Acerbas martini.

The HW white band is strongly angled on its outer margin.
It it wider than the dark brown border generally.

Unkana mytheca have a broad white band with straight margins.

Acerbas anthea have straighter margin & a distinct 'leak' of the white to the termen in the middle.

Acsrbas selta have both the white band & the dark brown border of equal width.
You can download the pdf on 'Bornean Endemic Butterflies'.
This shows all the Bornean endemics.

No 10. Choaspes subcaudatus.

The long black bar in the fold of space 1b never extend to the inner margin of HW in both species.(The ovate orange part.)
It is always in the fold .In pic 2, the bit of black is actually in the fold.

The two species can be separated thus.

Choaspes subcaudatus.
At rest HW lobe fols into a sharp point.
The visible black 'spot' large.

Hi Dr Seow,

There was this Cheritra sp. that I shot in Sabah and I've read briefly that in Borneo it should be C.pallida which is a synonym to C.freja ssp pallida. Are these two separate species? I couldn't find much more information for C.pallida so it is a little confusing.

It is a matter of opinion whether it is Cheritra freja pallida or Cheritra pallida.
As Cheritra freja pallida it is merely a subspecies (geograpical race) pallida of the widespread C. freja.
As Cheritra pallida it is raised to full species status ,& distinct from C. freja (which no longer exist in Borneo).

Species designation is matter of peer acceptance.

The latest Compilation on Bornean endemics 2021 does not list C. pallida.

The status may have change by now.
You can use either name.

As an example , consider Tanaecia iapis.
The nominate subspecies from Java is so different that most authors separate it from the other ssp in Sundaland.
Thus Tanaecia iapis iapis Java

https://www.jungledragon.com/image/1...pis_iapis.html

All the other subspecies are relegated to Tanaecia cocytina.
The species here would be T. cocytina puseda.
The genus change to Cynitia is a separate matter.
