Some tricky Arhopala from s Thailand

[DaveChiangMai]

Still working my way through a series of images from southern Thailand. Most of my Arhopala species I have been able to ID, plus a number posted here previously have aided with subsequent images I have. These below are still giving me a problems, so any help please.

Image 1. From Ranong. A. woodi?
Image 2, 3, 4. From Ranong. Same individual. Not sure.
Image 5. From Yala. A. norda or A. major?
Image 6. From Yala. Not sure.
Image 7. From Yala. Not sure.
Image 8. From Yala. I think A. centaurus with broken tail?
Image 9. From Yala. A. norda or A. major?

Similar but HW 'V' spot narrower & well-formed.
A. norda.

With many thanks for the detailed replies. Extremely useful.

#6 should be Arhopala labuana. selta has tails and does not have dentate submarginals

I am well aware A. selta have a tail it being a member of the alea subgroup.
The HW white marginal line is broken at vein 2 suggesting a broken tail.
However, A. labuana also have a largish tooth there & a broken tooth shows the same result.
The feature which suggest alea subgroup was that the postdiscal band appear fully broken at vein 2.
In A. labuanathe postdiscal band is only slightly dislocated at vein 2 & this can be seen in the example below & in the Borneo Lycaenid book L223.

However ,you are right about the triangular/dentate submarginal spots.
I thought it odd but the selta pix on the web were all too dark.

Thus 6 should be A. labuana
