) extends beyond its anterior margin. The difference between Paciphacops and ''Kainops'' is that ''Kainops'' has more eye facets than ''Paciphacops''. The skin (or sclera) is thickened and bulges compared to the edge of each lens. This genus can be found primarily in the United States and Australia.
