Difficult "hedge blues"

[DaveChiangMai]

I am reviewing all my "hedge blues" from old as for sure some are misidentified. I have copious notes gathered from ButterflyCircle which assist greatly, but these few are causing problems. Some feedback appreciated please.

Image 1. Photographed on Doi Inthanon, n Thailand. This looks like Udara albocaerulea, but I would not have expected to see sub-marginal lines on the hindwing.

Image 2. Photographed on Doi Lang, n Thailand. No real idea on this one.

Image 3. Photographed Doi Suthep, Chiang Mai. Possibly Udara dilecta, but the spots on the leading edge of the hindwing look too large for this species

1. Typical U. dilecta. HW small spots . spot 7 not darker than the rest.

2, There is a small spot at the base of space 7, seen in Acytolepis & Oreolyce.
This is Oreolyce archena.

Yutaka surprisingly does not include both species in his list.

TL Seow: Cheers.

Many thanks for this. Could explain why I was having so many issues matching these!
I suppose not included on current Thai lists as no specimens.
Though I would have thought Oreolyce archena should be on Yutaka website as known from Vietnam.
