Celatoxia marginata?

[DaveChiangMai]

Photographed on Doi Suthep, n Thailand this week. I can only make this Margined Hedge Blue Celatoxia marginata, known from this mountain, but scarce. It's the closest match I can find, though the hindwing margins seem much paler and better defined than the few other specimens and images on the web. Or maybe Udara albocaerulea? Would appreciate confirmation that this is indeed Celatoxia marginata.
Many thanks
