摘要：
A new actinopterygian, Roslerichthys riomafrensis gen. et sp. nov., is described from the Rio do Sul Formation (Early Permian) of Mafra, State of Santa Catarina, Brazil. This fusiform ray-finned fish is the smallest so far described for the "Lontras Shales." R. rionzaftensis, gen. et sp nov., is placed into the Amblyptertis Group of Gardiner and Schaeffer. Discussion is also offered about the taphonomic processes that led to the exceptional preservation of the fossils of these shales.
