A. pseudomuta group. Correction:alitaeus group
FW with spot 4 dislocated & shifted outwards from the band.
HW postdiscal band completely dislocated at vein 2 .beside the "V" spot.
HW postdiscal spot 7 directly above spot 6.

A. pseudomuta & alitaeus have more rounded spots.

A. pseudomuta.

A. alitaeus have very rounded dark-contrasted spots.

# 3. looks to be A. pseudomuta.



#4. https://www.inaturalist.org/observations/198208794
The underside markings are that of the amphimuta group.
The completely blue/purple upperside indicate A. amphimuta or moolaiana.
Since the HW tornus lack a white dot it should be A. amphimuta.



#5.https://www.inaturalist.org/observations/198208792
The markings are that of the amphimuta group.Upperside female.
Probably A. amphimuta.



#6 .https://www.inaturalist.org/observations/197002540
The markings are that of the pseudomuta group.
HW spot 6 is slightly rounded.
Probably A. pseudomuta itself.

#7. https://www.inaturalist.org/observations/196011840]

#7. is Arhopala ariana.

Pic 4 shows the underside markings are that of the pseudomuta group.Correction: alitaeus group.
Pic 1 shows the UpF with a dark border increasing at the apex.
This is as in Arhopala ariana.
The other males have the FW border a thread.( or broader still in aida.)

#8. https://www.inaturalist.org/observations/193482554

#8 is Arhopala elopura.

The underside is that of the pseudomuta group.
Note the spots forming the bands have straight margins.
The markings are little contrasted ,ie. the bands & the ground colour are of nearly the same tone.
This is seen in Arhopala elopura.

#9. https://www.inaturalist.org/observations/193386928

The underside is that of pseudomuta group.
It is rather pale & poorly contrasted.
Probably another Arhopala elopura.

#10. https://www.inaturalist.org/observations/192400182
Amphimuta group female.

The distorted "V" spot suggest Arhopala major.

#11. https://www.inaturalist.org/observations/187998657
Pseudomuta group male.Correction: alitaeus group.
The more rounded spot especially spot 6 suggest A. pseudomuta.

#12. https://www.inaturalist.org/observations/152490457

Arhopala moolaiana.
Underside of the amphimuta group.
UnH with a whitish spot at the tornus."V" spot rather fat.
UpF blue. The stronger black border suggest ssp maya.
