 In 1980 , Julio Contreras and María Rosi identified an Akodon from the province of Mendoza as Akodon varius neocenus ( now Akodon neocenus ) , but the following year , they identified it as a new species , named Akodon <unk> in a presentation at a scientific meeting . However , this name was never formally validated . In 2000 , Janet Braun and colleagues formally named this species Akodon oenos and allied it to the Akodon varius species group . The specific name , oenos , is Greek for " wine " and refers to the animal 's occurrence in the wine @-@ producing region of Mendoza . The common names " Monte akodont " and " wine grass mouse " were proposed for this species .
