The rocky intertidal gastropods of the Marine Priority Region No. 32 (MPR 32) in the State of Guerrero are one of the most studied invertebrates, however, little is known about their diversity and distribution. Here we report 16 new records of gastropods collected at six sites of the rocky coast (MPR 32) located in the State of Guerrero, Mexico. These records represent extensions of distributional range for an assemblage of species in different geographical scales, of which two are new for Mexico, five for the Mexican Transitional Pacific, four for the State of Guerrero and five for the MPR 32. These new records reveal the need for increasing taxonomic and biogeographic studies on the marine diversity in Mexico, especially in the Mexican Transitional Pacific Ecoregion.
