The lower 2/3 pf the FW outer margin is straight. Cn be very difficult to judge in photos.
Male narrower FWs.

3. I presume this is taken in Singapore.
This is a difficult one It appears to be a new species.
A male with the abdominal end strongly black-banded. FW spot 5 smaller than spot 4.

It is not P. mingo which have FW spots 4 & 5 of about equal size.
http://3.bp.blogspot.com/-f3wB2A2ujBs/TljGL_hdu_I/AAAAAAAABdc/afUjssvXasc/s1600/_MG_1531.jpg

It is not P. trachala which have FW spots 4 & 5 (of equal size) without overlapping the spots above & below; they are connected by the spikes.

It is not P. serina which is lightly dark-shaded, & more orangey.
http://www.butterflycircle.com/checklist/mugshots/Potanthus%20serina/Potanthus-serina-KSK.jpg

It looks very similar to this P. palnia which underside generally look greenish grey.
Range: India to SE Asia down to Sumatra, but not recorded from peninsular Malaysia.

In female E. acroleuca the HW patch is much wider in the lower half.

Post 10.

1. Euthalia monina male.
There are many more variations than what is shown in the reference books.

2. Pseudocoladenia dan.
The male can always be recognised by its horseshoe FW cellspot.

4. Nacaduba kurava male. FW termen straight; submarginal spots large with rounded inner margins ; HW submarginal spot 6 large typically quadrate.

Practically all Jamides can be recognised by the HW white striae forming a sharp spike near the inner margin (in a set position.)
eg. Jamides alecto male & bochus female.

Psyche
17-Apr-2018, 11:25 PM
Post 13.
They are both correct.

1. The silverstreak on the FW characteristic.

2. The paler forms of Arhopala alitaeus are often confused with pseudomuta.

A. alitaeus : darker, more contrasted & often purple-washed.
HW postdiscal spot 6 is more broadly rounded; submarginal spots are almost separate lunules (half-moons).

http://farm6.static.flickr.com/5165/5282906719_1937e569f7_b.jpg

A. pseudomuta ;Typically pale with poorly contrasted markings but some are darker causing confusion with A. alitaeus.
HW postdiscal spot 6 is more quadrate (squarish) & smaller ; submarginal spots are 'flatter' forming a running band.

Polytremis lubricans.

The HW arrangement of spots is that of P. lubricans.
There is spots 2 & 3, spot 4 is large, elongate, followed by a small spot 5.
The antennal tip is short, pale with a bit of orange.
The upper cellspot is variably large;
FW spots are yellow.
The dark lines are likely developmental faults.

Dear Dr Seow,

2) Arhopala amphimuta amphimuta?

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.

http://www.butterflycircle.com/checklist/mugshots/Arhopala%20major%20major/Arhopala%20major%20major%20-%20Tan%20CP.jpg

UpF shows broad brown border.
https://m.singapore.biodiversity.online/species/A-Arth-Hexa-Lepidoptera-000093?imageId=0

Abdominal end is that of a male; UpH is brown.
https://wanderingbutterflyeffect.files.wordpress.com/2010/03/6a0100a801ee89000e0123de1c48c6860d.jpg



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.
https://m.singapore.biodiversity.online/images/speciesImages/medium/ff936162-ec58-f1b8-8222-dd50ee5d7992.jpg
https://m.singapore.biodiversity.online/images/speciesImages/medium/c2036f71-516e-2b84-0dcf-f8520e538feb.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/Arhopala_amphimuta#/media/File:ArhopalaAmphimutaMillerianaMUpUnAC1.jpg

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

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

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.

3. Probably female Pelopidas agna.

Post 62.

Probably Miletus gopara female. Correction: Miletus biggsii.

M. symethus.
This can be eliminated because the HW postdiscal spots are crescent with rounded outer margins.
Apices of FW & HW are whitish shaded.
Male & female.

https://yutaka.it-n.jp/lyc2/80270010.html


M. biggsii.
Underside more uniform & HW postdiscal spots are blocky.
UnF cellend mark is a thin line.
Male & female.

https://yutaka.it-n.jp/lyc2/80260001.html


M. gopara.
Underside with uneven shading & whitish apices as in symethus.
HW postdiscal spots part crescent & part blocky. FW postdiscal spots in line.
UnF cellend mark broad band-like.
Female with a variable 'tail' at vein 4.
https://3.bp.blogspot.com/-_5xBXxlKdTI/W-g1uXe3ujI/AAAAAAAAep0/a_8ZVOyCuhcDDpoTPCh9lNNEZcAD2EViQCLcBGAs/s1600/DSC_4275.JPG

Although the tail is not that prominent in thisfemale, comparing the FW cellend mark between gopara & biggsii seem to suggest the former.(Use the Yutaka images.)

63-64.
Best left as Miletus biggsii female.

The tail is not long enough to be that of M. gopara female.
The FW postdiscal band's spot 6 is dislocated.
In M. gopara this is typically in line. (Varies.)

Id features are often vague & variable in Miletus.


No. 65.
Female Hypolimnas bolina bolina.
The female is very variable.
