Hattopsis is a genus of echinoid in the family Arbaciidae. It was described 1992 from specimens in the UAE. There were 2 species described, though one was moved to another genus:[2] Hattopsis paucituberculatus (now in genus Noetlingaster as Noetlingaster monotuberculatus) and Hattopsis sphericus, both are known from the late maastrichtian.[3]
