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.

https://en.wikipedia.org/wiki/Arhopala_aida#/media/File:ArhopalaAidaAidaMFUpUnAC1.jpg

# 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.

[Psyche]

#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.)
