Sigmodontine rodents are well represented in Northwestern Argentina, but information regarding their distribution in La Rioja is scarce. We add new information for seven species from seven localities in the Famatina range. These new records were obtained using both captures and owl pellet analysis. We cite the first record of Neotomys ebriosus in La Rioja. The collection locality is unusual for this species because of its low altitude and xeric conditions. Other notable results include the second records from the province of Abrothrix andina and the genus Oligoryzomys.
