The typical form of this species was based upon immature 

 individuals measuring only up to 75 mm. long. Until the adult 

 is known it seems to me impossible to classify the species with 

 certainty. It is undoubtedly nearly allied both to the following 

 species," P. phillipsi from North-west Somaliland, and to the 

 more southern Masailand form P. r/regorii, but it will probably prove 

 to be at all events subspecifically different from both.
