Morphologically, it is somewhat similar to R.hoffmannri, R. palmarum, R. burrus, R. simalurensis, and R. lugens, although more research is needed to deter mine their true relationships. Monotypic.

Dorsum is rich dark brown, speckled buff and slightly lighter on sides due to suffusion of gray. Hairs are dark brown or black, although some have buff banding around tips that cause speckling. Venteris grayish, tinged with silver and buff, and hairs have gray bases and translucent or buff tips. Rusty patch occurs on chest, chest to chin, or chest and throat. Feet are dark brown dorsally and ventrally on hindfeet and light brown ventrally on forefoot. Ears are small and similar in color to dorsum. Tail ¢.87% of head-body length and unicolored dark brown.
