Lund’s Atlantic Tree-rat Phyllomys lundi French: Rat-épineux de Lund / German: Lund-Kistenbaumratte / Spanish: Rata arboricola atlantica de Lund Taxonomy. Phyllomys lund: Leite, 2003 , “Fazenda do Bené, 4 km SE Passa Vinte, Minas Gerais, Brazil, 22°14’S 44°12°’W, 680 m.” This species is monotypic. Distribution. SE Brazil, SE Minas Gerais and N Rio de Janeiro states. Descriptive notes. Head-body 184-209 mm, tail 200-204 mm; weight 145 g. Lund’s Atantic Treerat is among the smallest species of Atlantic tree-rats. It has orange upper part, mixed with black hairs, and neck and thighs are predominantly orange. Spines are conspicuous from neck to tail. Venter is creamy, with white base hairs. Tail is brown, 100-110% of head-body length, and hairy throughoutits length.
