Juliomys ossitenuis Costa, Pavan, Leite and Fagundes, 2007 was previously known in Brazil from the Atlantic Forest of the Southeastern Region to the Dense Ombrophilous Forest and Araucaria Forest of the Southern Region. The new record from Chapecó, in Santa Catarina state, confirmed by morphological and cytogenetic analyses, extends its distribution about 300 km westwards. This is the westernmost record for the species, in a region characterized by the transition between deciduous and Araucaria forests.
