The nomenclatural status of 17 class-series nomina (13 diplorhizonyms and 4 haplorhizonyms), based on the single or primary stems Anura, Urodela and Batrachia that had been set aside in our previous papers of this series is examined. None of them is currently valid under the Duplostensional Nomenclatural System, four of them are unavailable (including "Batrachoidaria" Betancur-R. et al., 2017), and the status of four of them, based on fossil nucleogenera, is still unsettled because of missing information concerning the phylogenetic relationships of some of these genera.
