Are these two different species of Amathusia?

[Tai LA]

Taken at KL Butterfly Park...not very pristine

A. I ID this as Amathusia perakana - due to the darker brown band


B. I ID this as Amathusia phidippus - paler in colour


Are they the same species? What are the key ID features to tell them apart?

Thanking you in anticipation

The Palm Kings are very difficult to ID based on the underside alone.

1. Probably A. friderici female.

2. A. phidippus.

The main thing is to look at the HW 4th dark band that is inner to the main dark band & the FW main band itself.

1. A. phidippus;
FW main band intact; HW 4th band not notched .& usually flared at the top.
