Well, the dorsal pattern of tredecimguttatus is the obvious difference, but as we know, they don’t have any dorsal pattern in parts of Africa. I wonder if the hourglass is a way to tell them apart. I know tredecimguttatus has a similar pattern to menavodi. Size may also be a difference.

As usual, the most reliable way would be to use a microscope to analyze the reproductive organs.

I have bought slings from someone who has took 2 cocoon's from Marokko. The female where he took the cocoon from was totally black, but both widows get darker with age. So it can be both.. Latrodectus cf trededimguttatus/ cf dahli “marokko” This is one of the female slings if got..
