Now this one looks like O. boehmi! If it were any other, it would have to be a different color morph of them from what I have seen most regularly. I will note, the items in coloration difference are the vesicule being black and the stripe of black down the O. walberghii's tergite in more common color morphs of the species. The species in question, does not have the common stripe or st least, not as noticeably, and the vesicule is very light in coloration when compared to the last caudal segment.
Thanks for posting them, Paul.
I will be most pleased to add some of these scorps to my collection!
