Tagiades litigiosus.male. Correction: Tagiades menaka.
The 2 similar species can be confused.

Look at the outer spots there are 5 here in the male.
Last one is spot 3. The two bigger inner spots are costal spot & upper cellspot.
Female have additional spot 2, & lower cellspot.

Dr. Seow,
Thanks for your ids.

I have a question to review and clarify.
For #1, can it be T.menaka?
My reasoning, per CP5, T.menaka
- also has a small white dot in space 3,
- the photo plate 113.8, there is an extra "postdiscal black spot in space 1b" in white area of hindwing.
- "confined to the forested hills" while T.litigiosus is "known in Peninsula only from Kedawi"

Cheers, SL LIew

You are right #1 should be T. menaka.

The postdiscal spot in space 1b is so vague that it disappear when I look downwards.
There is another postdiscal spot to look for.
Above the 4th marginal spot is another small postdiscal spot just besides the large partially hidden postdiscal spot in the upper corner.
This is always present in T. menaka.

This small spot is absent in T. litigiosa.

Thanks again Dr. Seow.
Always appreciate your help. It motivates me to continue to go out to nature and to seek and discover more butterfly species.
