A new scorpion species, Hottentotta sousai sp. n. is described based on two males and two females collected around Tan-Tan, in southern Morocco. Sousa et al. (2011) reported four distinct clades within the genus Hottentotta from Morocco. This description of a new species is based on the specimens from the Low Draa Valley clade, which is closely related to Hottentotta gentili (Pallary, 1924). The new species, however, differs from the central clade of H. gentili by 12.1% divergence in COI mitochondrial DNA sequence, and is morphologically characterized primarily by very dense setation over all body parts and a lower length to width ratio of all metasomal segments.
