Genus Paralampas : Paralampas is also an extinct cassidulid genus, with a fossil record ranging from the Maastrichtian to the Eocene (~72.1–33.9 Mya). Kier (1962) suggested that Paralampas could be a synonym of Rhynchopygus , but he was unable to analyse any specimens. Later, Smith & Jeffery (2000) considered Paralampas a subgenus of Petalobrissus , but the latter has a tetrabasal apical system and a longitudinal periproct. To our knowledge, there are seven nominal, widely distributed species of Paralampas . The following two species were included in our analyses: the type, Paralampas pileus Duncan & Sladen, 1882 , and Paralampas rancureli Tessier & Roman, 1973 .
