Eleven new records of marine gastropods from several localities in west-central Argentina are hereby presented, including the following new species: Proconulus kotrus, Calliotropis (Riselloidea) ligosta, Lyosoma truquicoensis, Exelissa crassicostata, Cirsocerithium agriorivensis, Cataldia? binodosa, Vanikoropsis? leviplicata and Tornatellaea neuquina. These records were recovered from two Early Cretaceous units of the Neuquén Basin, the Mulichinco (Valanginian) and the Agrio (upper Valanginian—upper Hauterivian/lowermost Barremian) formations. The families Proconulidae, Calliotropidae, Neritidae, Cryptaulacidae, ?Pseudomelaniidae, Vanikoridae, Epitoniidae and Acteonidae are represented whilst one record is yet to be assigned at the family level.
