Thank you.

Post 47.

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.

Less typical.
Upperside is typical male.
UnH postdiscal band straight but 'V' spot slightly off.

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.

A. major is much more common than A. amphimuta.

Judging from the combination of features both are more likely to be A. major.

Thank you Dr Seow.

Correction.

In looking at these examples of the same ssp amphimuta from S. Thailand.
The postdiscal band above the 'V' spot is also partially broken, so a well-shaped 'V' spot is still important in the identification.

Use google zoom to see the markings.
