The 18S rDNA was used to infer oral ciliature patterns of evolution within the family Ophryoscolecidae, with the addition of five new sequences of ciliates from the genus Ostracodinium . Our data confirmed the monophyly of the subfamilies Entodiniinae and Ophryoscolecinae, but more analysis would be required for the definition of the status of the subfamily Diplodiniinae. The oral infraciliature patterns reflect evolutionary divergence in the family Ophryscolecidae, observing monophyly on Entodinium ‐type, Diplodinium ‐type, Ostracodinium ‐type, Epidinium ‐type, and Ophryoscolex ‐type. The ancestral infraciliature of Entodinium ‐type cannot be proven, however, the position of Entodinium ‐type showed closer of Diplodinium ‐type than Ophryoscolex ‐type, corroborating previous studies using morphological characters. The observed inconsistencies reflect the need to increase the number of 18S rDNA sequences to family Ophryoscolecidae and investigate the evolution of this group using other molecular markers.
