Dear Dr Seow,

I think you got all correct.
1. It is always good to have extra views. The main problems are.
a. The antenna view here is the underside of the club, which is always prominent white in all species, thus not defining.
b. The FW upper cellspot is not visible.c. Colouration does not suggest C. cormasa ,which is redder.
The two nearest species C. bromus & malaya have the FW & HW little contrasted.
Compare.
All males.
C. cormasa. Note contrast between FW & HW.

C. bromus.

C. malaya. Hardly any pale area on the antenna.

2. It is difficult to define what is B. farri in Singapore.
It is described as more often fully spotted ,thus Complete Paintbrush Swift.
No male in Singapore is fully spotted. It is also described as silky brown.
I am simply assuming the dark form is B. oceia.
Probable B. oceiamale.

3. In Euthalia aconthea some females have the HW arrowheads pointing outwards.
See female from Surat Thani.
