Morphological differences between S. gigas (Tanger, Chipiona and Sidi Kaouki) and S. ferreri (Aglou and Deghaimis) (see Table 1 for locality details). Note the poorly marked carina on the anterior elytral region in S. ferreri, which are relatively well-marked in S. gigas (indicated by a red arrow in one selected specimen for each species).
