It has a long tail, uniformly dark brown in color above and below; tail scales are visible to eye, with 16 scale rows per cm; caudal hairs are short (<2 scale rows in length); and there is no apparent terminal pencil of hairs. The hind feet are distinctly broad and clothed in orangish hair above. The dorsal coloration is dark orangish brown, paling laterally with a weakly developed, but visible orange lateral line; ventral fur color is uniformly graybased tipped with buff. The dorsal fur is thick and woolly in appearance. Distinct pale orange postauricular patches are present, uniquely so among the species encountered along the Rio Jurua´.

The upper incisors are more orthodont than in the other species. An alisphenoid strut is present in one, but not the other of the two available specimens; the tegmen tympani is in contact, but does not overlap, with the squamosal; the subsquamosal foramen is small, but open, in both specimens. The incisive foramen is short and slightly oval in shape, not distinctly teardrop in shape as in both
