My computer screen's gama is very low so I can not see details very well.Well it has a black telson which narrows it down to spinifer, petersii, laoticus. You can distinguish between these three by the granulation patterns on the sides of the prosoma, which is difficult to see in your picture. It does have granulation though, which rules out laoticus, so that leaves spinifer and petersii. Petersii has a relatively straight pattern of granulation, which yours doesn't, which makes it a spinifer.
