Diagnosis Horne & Whittaker, 1985: 137:
"Remarks: Many species assigned to Paradoxostoma by early authors (e.g. Brady & Norman, 1889) are now placed in the genera Cytherois and Paracytherois, both described by G. W. Muller (1894). The three genera are most easily distinguished from each other by their mouthparts; in Cytherois the mandible is slender but not styliform, while Paracytherois has a styliform mandible but lacks the suctorial disc of Paradoxostoma." [details]
