Thylamys macrurus is larger than other Thylamys species on average, but possesses most of the other external features shared by members of this genus, including an incrassate (fatty) tail. Caceres et al. (2007) found that males are significantly larger than females (52.4 g vs. 41.0 g). Voss et al. (2009) noted a range in mass from 30 g to 57 g, with total body lengths ranging from 251 mm to 308 mm.
