H. spinifer or H. petersii

[Cecropia1999]

I was recently sold this Asian Forest Scorpion and the dealer assured me that it was H. spinifer, but after looking around I believe it to be actually H. petersii. Could anyone tell me the exact species and the sex? Thanks

Is this the same individual as the other thread, or a different one? It looked like a male in the other thread, but after seeing these better pictures, this is a female.

The species is Heterometrus silenus (ex petersii).

The species is Heterometrus silenus

Are you going by the shape of the claws and lack of granulation on the carapace? I'm confused as I don't see any granulation which indicates Laoticus. Please correct me here.

Chelae shape and black telson indicates either silenus or laoticus.
There is a patch of granulation on the side of the carapace, under the median eyes. This is most notable in the 3rd picture. This patch is the trademark granulation pattern for H. silenus, whereas H. laoticus would not have any granulation here. If you don’t know what I mean, there is a clear picture in this thread under ‘what species is my Heterometrus?’:

Like @Joey Spijkers said, this is a female Heterometrus silenus. Note the lack of the enlarged tooth on the moveable finger of the chelae.

H. spinifer have narrower chelae, larger/more pointed granules on the dorsal keels of the 5th metasomal segment, and typically have a red telson as adults.

Granulation is also apparent on the lateral areas of the carapace, and the posterolateral areas of the tergites. In H. laoticus these areas are completely smooth.
