1. Jamides celeno.
Colour may be brown or grey.
2 & 3.
Both are Jamides alecto ageladas.
J. alecto & elpis are easily confused.
J. elpis pseudelpis.
Male upperside light blue & unmarked.
UnF white striae narrow in the male; in female the inner (discal) white are narrow ,while the outer submarginal striae relatively broad.
HW the spike formed by the discal band relatively broadly pointed.

Dear Dr Seow,
Appreciate your id for the below species:
1) Arhopala amphimuta amphimuta?

2) Arhopala amphimuta amphimuta?

Thank you.

There is no absolute features on the underside that will separate these two species confidently.
Here are some examples with upperside confirmation.
Arhopala major major.
Unh 'V' spot in space 1b distorted often 'L' or "j" shaped.
Postdiscal band (spots 2, 3, 4, & 5) above the 'V' spot always broken or dislocated.
Examples. Males with UpF broad brown border confirmation.

UpF shows broad brown border.

Abdominal end is that of a male; UpH is brown.

Arhopala amphimuta amphimuta.
Unh 'V' spot more nearly of equal arms, the upper arm almost equal.
Unh postdiscal band above the 'V' spot usually straight & unbroken. Best single feature . Correction ;Not true over a larger sample.
Upperside male blue to the margin.
TYpical males.

http://4.bp.blogspot.com/-J9Xmngyim6...+amphimuta.jpg
Less typical.
Upperside is typical male.
UnH postdiscal band straight but 'V' spot slightly off.
https://m.singapore.biodiversity.onl...50ee5d7992.jpg
https://m.singapore.biodiversity.onl...520e538feb.jpg
From southern Thailand.
'V' spot is well-shaped but postdiscal band is broken.
Note UpF brown border is much wider than typical amphimuta male.
This suggest a strong hybrid element with A. major. Correction: Probably not true as this is a different subspecies.
https://en.wikipedia.org/wiki/Arhopa...naMUpUnAC1.jpg
A. major is much more common than A. amphimuta.
Judging from the combination of features both are more likely to be A. major.
