Lembeh porcelain crab

I found this teeny crab at Nudi Falls on a night dive. I can't seem to figure out what it is. Closest guess is some sort of Aliaporcellana sp. Any ideas on the I.D. would be appreciated.

Cheers,

Marli

If only the people working with these things would include color photos as well as line drawings we'd be able to ID more of what gets photographed. Until then..... I don't even know enough to be confident about genus, sorry.
