Dear Dr Seow,

Are these Arhopla atosia or Arhopala lurida?

The first should be Arhpala pseudomuta.

The 2nd should be Arhopala atosia.


In the 1xt pic, the HW spot 7,s inner margin is aligned with that of spot 6.
In A. atosia and lurida, spot 7 should show some degree of extending inwards from spot 6.
Also, all the four FW upper postdiscal spots are dislocated giving an irregular alignment.
This is seen in at least 90% of A. pseudomuta but rarely in atosia and lurida.

In ht6e 2nd pic HW spot 7 is distinctly shifted inwards of apot 6.
A. atosia and lurida are very similar.

A. atosia is poorly contrasted; on the HW the spots on the inner half are only a bitdarker than the outer spots.
A. lurida is better contrasted, the inner HW spots are much darker than the outer spots.



Arhopala pseudomuta.
Note the irregular upper four FW postdiscal spots.
HW spot 6 and 7 are almost aligned on their inner margins.

Arhopala atosia.
FW spot 4 dislocated out from spot 5 above it.
HW spot 7 at least slightly inwards of spot 6.
HW inner half spots slightly darker than outer half ones.
Male disc is larger, extending well into cell and space 1b.

Arhopala lurida.
Markings as for A. atosia but better contrasted.
UnH inner half spots noticeably darker,compared to the outer half spots.
Male disc smaller, not extending much into cell or space 1b.

1. Arhopala athada athada ,most likely.

The FW upper 4 postdiscal spots are all visible, and spot 4, the lowest is not dislocated put.
HW submarginal and postdiscal spots are well-separated, indicating a large species.
HW spot 6 touches both spot 5 and the cellend bar.
The shape of HW spots 6 & 7resembles somewhat that of A. silhetensis but the overall appearance is that of A. athada.


A. athada :HW spot 6 more quadrate often astride spot 5 and the cellend bar; spot 7 more upright .

The members of the asmaller alea subgroup are often confused with A. athada.
Their smaaler size means the spots become closer, on the HW the submarginal and pstdiscal spots come close and almost touch.
These two pix, probably A. sublustris are misplaced under A. athada.

A. silhetensis is a larger species the spacing between the spots/bands very obvious.
HW spot 6 narrower base and usually does not touch spot 5 ,and often not the cellend bar as well.
HW spot 7 is typically oblique with snuous margins.

2.Arhopala epimuta apiala.
The FW spots are mostly hidden, but the HW spot5,6,& 7are as in A. atosia.
There is a slight tooth at vein 2. and a prominent white tornal dot on the cilia.

3. This is fairly typical Arhopala athada.
