heterometrus ?

i picked up this male today and as usual for the shop was just labled as asian forest.
it look's similar to my spinifer's but im unsure, not the best pic's but what do you think?





these are the best shot's of the carapace granulation i can get at the moment will take some more when there's daylight



he was quite sluggish an probably dehydrated as they had him in a cricket tub on dry orchid bark but he has perked up a lot now he's on damp coco fiber an in a decent sized tub with some cork to hide under

thank's, was hoping it was spinifer but hey it's another one off the list of heterometrus sp i want to get.

what are the identifying mark's for petersii?
is it just the granulation on the carapace

Here are the ID keys with examples:
