Sigmodontinos (rodentia, muridae) del holoceno inferior de Bolivia

Abstract

Se estudió una pequeña colección de muroideos (Rodentia, Muridae) fósiles provenientes del Miembro Media de la Formación Nuapua (Holoceno inferior) exhumada en la Quebrada de Nuapua (20° 52' S; 63 ° 04' O; 500 m sobre el nivel del mar), departamento Chuquisaca, Bolivia. Se determinaron restos asignables a los sigmodontinos Holochilus chacarius balnearum (Oryzomyini), Necromys sp. (Akodontini), Calomys sp. y Craomys sp. (Phyllotini), todos generos y especies actualmente distribuidos en el sudeste boliviano. Se discute la taxonomía del genero Holochilus en la región, justificándose a través de rasgos de la morfología dentaria la diferenciación de H. sciureus, H. chacarius y H. brasiliensis. Las poblaciones actuales del genera en el sureste de Bolivia se refieren a la especie Holochilus chacarius. Asimismo, se destaca que el registro de "Zygodontomys" efectuado por autores previos para la muestra fósil de Nuapua corresponde al genero Necromys (= Bolomys, parte). Los escasos sigmodontinos fósiles conocidos para Nuapua sugieren condiciones chaqueñas para el Holoceno inferior, similares a las actuales en el área.
