Abstract

D´HIRIART, Sofía; BARBIERE, Franck; ORTIZ, Pablo E  and  JAYAT, J. Pablo. First record of the genus Andalgalomys (Rodentia, Cricetidae, Sigmodontinae) from Santiago del Estero Province, Argentina. Mastozool. neotrop. [online]. 2017, vol.24, n.2, pp.457-465. ISSN 0327-9383.

In this work we document the presence of the genus Andalgalomys in Santiago del Estero Province, northwestern Argentina, based on specimens from a locality in Chaco Seco located more than 270 km to the south and 160 km to the east of the nearest known localities. Cranial and dental mor­phometric values of the specimens obtained allowed us to distinguish two clearly differentiable sizes and refer them tentatively to Andalgalomys cf. A. roigi and Andalgalomys sp. This locality represents the first putative area of sympatry for two species of the genus.

Keywords : Chaco Seco; Geographic distribution; Northwestern Argentina; Phyllotini.
