Akad. Wiss. Munchen, 3: 196 . Type Locality: Unknown. Vernacular Names: Dark Armored Tree Rat . Distribution: Brazil . Conservation: IUCN – Data Deficient as Mesomys obscurus . Discussion: Known only from the original description. Tate (1935) placed it first in the genus Mesomys (p. 413) and then in the genus Echimys (p. 432). Cabrera (1960) followed Tate’s first allocation and retained it in Mesomys with reservation, a placement followed by subsequent authors ( Corbet and Hill, 1991 ; Woods, 1993 ). Emmons (1993 a ) suggested that the original illustrations precluded identity with Mesomys and Emmons (In Press) placed it in the genus Makalata .
