Heterometrus spinnifer or petersii?

I am pretty sure she is a petersii but wanted other opinions.

Hmmm possibly spinifer @Collin Clary ?

Looks like petersii, it's definitely not spinifer. True spinifer is actually hard to find in the hobby, in the US anyway. Soooo many petersii are sold here as spinifer. Here's a good pdf to look at http://www.science.marshall.edu/fet/euscorpius/p2004_15.pdf The thing you notice about it real fast is sheen, this one has a powder-coat/matte finish on it, spinifer has a polished shine to it.

Spinifer also generally has a white (while juvenile) or brown (while mature) telson similar to a pandinus imperator. The telson on this individual appears to match the body. I would lean towards petersii.

Cool thank you!

If the telson is the same colour as the body it is Either H.petersii OR H.laoticus - H. laoticus are the main " Forest Scorpions " imported in large numbers - at least here in Europe.

Claws (pedipalps) look like H. beccaloniae
Or H. bengalensis
They don’t look anything like petersii.
I’m not familiar with laoticus.

I don’t mean to hijack, but what do these things look like. I’m told they are adults but they look like juveniles.
Listed as Spinifer also.

This is what I understand is Petersii
The 1st 2 are adults and the last is a juvenile.

Certainly not petersii or laoticus or spinifer. The former two have a swelled chella while the latter has a elongated one. And spinifer also process a red telson. My best guess is the Heterometrus bengalensis, due to the shape of its chela and the carinae on it. The only problem is according to the only pics I have of H.b, its telson is red. But there might be a possibility that just like H. cyaneus, the color of telson might vary.

The ones in your group are either H. laoticus or H. scaber depending on location, both have blackish/reddish brown claws and vesicles.

You are correct with your understanding of these ones as H.petersii.
