Proctoporus and Opipeuter have been distinguished by the presence of prefrontal scales in Opipeuter and absence in Proctoporus, but this character has been demon- strated to be highly variable within members of the family Gymno- phthalmidae (Köhler and Lehr, 2004). Indeed, prefrontal scales are present in both O. xestus and the two species of Euspondylus that are nested within Proctoporus in our analyses, proving the highly homoplastic condition of this character state. Proctoporus species and O. xestus also share the condition of a transparent disc in the lower eyelid, a character that nonetheless appears in Potamites and other Gymnophtalmids (Doan and Castoe, 2005), being thus either homoplastic or symplesiomorphic.
