Purse crab in Lembata, Indonesia

Anyone know what kind of purse crab this is? They were either fighting or mating.

I'd say a male & female either mating or the male carrying her around to make sure no other male can mate with her. Similar crabs are on the web as Leucosia pubescens - check out Teresa Zubi's site. In one of her shots both crabs are upside down & you can clearly see that one is male & one is female.
