Akodon spegazzinii, Spegazzini's grass mouse, is a rodent in the genus Akodon. It inhabits grassland and forest in northwestern Argentina at 400 to 3,500 m (1,300 to 11,500 ft) above sea level. Compared with other members of the Akodon boliviensis species group, it is medium in size, with a head-and-body length of 93 to 196 mm (3.7 to 7.7 in) and a mass of 13.0 to 38.0 g (0.46 to 1.34 oz). The coloration of its upperparts varies considerably, from light to dark and from yellowish to reddish brown. The underparts are yellow-brown to gray. The eyes are surrounded by a ring of yellow fur. The skull contains an hourglass-shaped interorbital region (between the eyes), and various features of the skull distinguish the species from its close allies. It reproduces year-round. First named in 1897, the species now includes mice that had been given other names from variable populations. Because it is common and widely distributed in its habitat, it is considered a species of least concern. (Full article...)
