Respected T L Seow Sir,
Can you share some images of P. mathias where we will get clear upper wing view (male dark brand, FW spot 2,3)

Regards,

I kind of forgot that P. mathias is also found in Africa since my reference book did not mention it.
In fact both P. thrax & mathias are found widely in Subsaharan Africa.

As there is no example of P. thrax with whitish shading through out the Mediterranean & the Middle East, this means the examples with white marginal shading on the wings are mis-ID'ed P. mathias.
eg.http://tolweb.org/Pelopidas_thrax


The three species can now be separated with greater confidence.

Pelopidas thrax.
1. Upperside; FW with upper cellspot typically wide (elongate horizontally),often teardrop shape.
Male with the brand whitish.
Female with spots rather larger than in P. agna & mathias female.
2.Underside uniformly light brown.
HW spots with darker brown margins ,some of the spots reduced to dark rings/spots.
Underpart of body generally whiter thn the other species.
Males.

Subspecies masta Sikkim to Manipur.
UnH with spots 4 & 5, the rest absent or reduced to dark spots.


Pelopidas agna
1. Upperside both cellspots rounded.
Male brand dark.
Male spot 2 & 3 typically narrow & rectangular.
A line through the two cellspots usually bypass or just tip the lower end of the brand.
2. Underside uniformly brown ,often ochreous.
HW spots not margined in darker brown.

Pelopidas mathias
1. Upperside FW cellspots rounded.
Male brand dark.
Male spot 2 & 3 typically quadrate but may be somewhat rectangular.
A line through the two cellspot cut the lower part of the male brand.
Female spots as in the female P. agna . A line thru the 2 cellspots is closer to the spot in space 1b than in the case of the P. agna female but not reliable.
2. Underside greyer brown ,uneven, with pale shadings in the marginal areas ,variable; HW spots may have darker margins.

The best identification is from the underside

P. mathias ; Un with paler whitish shadings in the marginal areas ; spots may have dark margins ;UpF male brand dark.

P. agna .UnH uniform brown, ochreous, spots without dark margins; UpF male brand dark

P. thrax; UnH uniform light brown ;spots with dark margins, some spots may be reduced to dark rings/dots; UpF male brand whitish, upper cellspot elongate .
