Diagnosis 
CommentNomenclature: This name is preoccupied in Cordylus by C. nebulosus A. Smith 1838, a synonym of C. cataphractus, but as the latter appears to be the sister species of all other Cordylus (Frost et. al. 2001), it required to be placed in a new monotypic genus, so that a new name will not be required (Mouton, pers. comm., STANLEY et al. 2011).

Ovoviviparous.

Abundance: only known from the type locality (Meiri et al. 2017). 
EtymologyThe designated name, Pseudocordylus nebulosus, which literally means the cloudy or dark crag lizard, refers to its occurrence within the mist belt of the Hottentots-Holland Mountains, as well as its melanistic body colour.
