1. Using the key this does sort of keyed out as A. agrata.
However A. agrata is quite consistent in appearance.
FW spot 9 obscure/absent HW spot 6 large trapezoid.
P. Thailand

P. Malaysia.

Examples from Borneo are similar.

This one differs in the FW band being very narrow & the HW spot 6 differently shaped.
Possibly a variant or aberration.

2. A member of the alea subgroup, HW band completely dislocated at vein 2.
Either A. selta or phaenops.
Probably A. selta from the purple flush.

3. A. moolaiana.
HW toothed at vein 2 & faint white dot at tornal cilia.
HW spot in space 1b broadly 'V' shaped. HW spot 6 large.

4. Should be correct as A. delta.
The deciding factor is HW band is only partially dislocated at vein 2.
In the similarly marked A. lurida/atosia the band is comletely dislocated at vein 2.

A. delta.
