This looks to be some form of E. monina.
The HW blue is evenly broad throughtout.
The FW have the two subapical spots as in some monina. This has also extra spots.
Probably Tanaecia munda.
The HW arrowheads are set closer to the margin as in the males of T. palguna & munda.
In T pelea the arrowheads are midway.
The FW arrowheads in T. palguna are short & closer to the margin.
No proper image of T. munda.
TL Seow : Cheers.
PS. T. pelea female with extensive white. Note palpi 3rd segment long & needle (diagnostic).
Probably correct as T. munda female. Note palpi 3rd segment short & thick.

Thank you again, Dr Seow! These butterflies look so alike!
