Heterometrus sp ID

[sdsnybny]

I would very much appreciate any help with a positive ID on these two clutch mates that were sold as Heterometrus cyaneus. They are not full grown only about 4-4.5" including tail. I have raised them from about 1.5" scorplings. @Collin Clary @G. Carnell
Thanks in advance.

Can't say for sure, a full body pic with the Telson included may help, but... here is a review of the genus Heterometrus. You may be able to ID it based on the information provided in the publication.

Dark telson, dorsal keels on 5th metasomal segment consist of relatively minute granules, chela fairly round (even at this age), and granulation on the carapace and tergites.
