Walliserops (named after Prof. O. Walliser of the University of Göttingen) is a genus of spinose phacopid trilobite, of the family Acastidae, found in Lower to Middle Devonian age rocks from the Anti-Atlas Mountains of Morocco. All species of Walliserops possess a three-pronged "trident" that protrudes from the glabella. Walliserops is most closely related to the genus Comura.
