First documented record of Holochilus brasiliensis (Desmarest, 1819) and Calomys laucha (G. Fischer, 1814) in the state of Santa Catarina, south Brazil

Abstract

Studies on the richness of small mammals in the Brazilian South Region are recent and point out the need for using varied methods. This way, this paper contributes to knowledge on the fauna of small sigmodontinae rodents in Santa Catarina, including Holochilus brasiliensis and Calomys laucha in the list of species with confirmed occurrence in this state. The records of H. brasiliensis refer to Laguna (n = 2) and Timbe do Sul (n = 1). In turn, C. laucha presents 23 records from Capinzal. The entire material is represented by skull fragments from owl pellets samples collected from nests and feeding perches of the Tyto alba.
