These are small arboreal rats with long tails. Head and body is 8.4–17.5 centimetres (3.3–6.9 in), tail is 12.8–24.5 centimetres (5.0–9.6 in), and weight is 23–122 grams (0.81–4.30 oz).[1] The fur is grey to brown above with a white belly. They are restricted to forests where they spend all of their time in the canopy. They live in groups usually consisting of a breeding pair and their offspring (usually one to three) (Nowak, 1999).
Musser and Carleton (2005) considered Chiruromys to be a member of the Pogonomys Division within the Murinae along with the genera Pogonomys, Hyomys, Macruromys, Mallomys, Coccymys, and Anisomys. It is considered a New Guinea Old Endemic, part of the initial wave of murines colonizing the island.
