Separation of Arophala birmana and A. paraganesa

[DaveChiangMai]

I am looking for a reliable feature to separate A. birmana and paraganesa. I have a feeling some of my identifications are not correct.
This one was photographed at Omkoi, nw Thailand, Jul 2024. Dry Dipterocarp forest at 950 m. I'm not now sure which species.
Many thanks.

This one is Arhopala birmana.

Arhopala birmana.
FW postdiscal brown band & the adjacent pale whitish band are strongly dislocated at vein 4.

Arhopala paraganesa.
FW postdiscal band only slightly dislocated at vein 5, so it & the adjacent whitish discal bands have mostly regular margins.

Arhopala ganesa.
FW postdiscal band more strongly dislocated at vein 5 so it & the whitish discal band are angled on their common margin at vein 5.
HW ground colour more brownish & less contrasted.
FW apex hooked.

Many thanks for that, which confirmed my suspicions. Fortunately I don;t have to worry about ganesa in Thailand.
