While having a similar general facies to S. vertebralis mihi, the 

 form is shorter, squarer, and more parallel, the colour much 

 darker, especially on the abdomen, while the widely different 

 shape of the prothorax, its dentate edge, and coarser sculpture 

 distinguish it, The female specimen is lighter in colour, with 

 more dilated tarsi, and more dentate edge of prothorax than the 

 male.
