Still others are more grayish or more buffy. Some species have a bright chestnut anal patch and a faint dark line down the middle of the back. D. lokriah has a brilliant rufous patch on the outer side of the hips. The furry coat of this genus is fairly soft and full.

Females have three pairs of mammae.
These squirrels are found at elevations from sea level to 3,400 meters but dwell mainly in montane forests. They seem to spend considerable time on the ground and in trees within 4.5 meters of the ground. The diet includes fruits, nuts, other plant material, and insects. The voice of D. pernyi apparently has great power and resonance, and D. lokriah emits a sharp squeaky chatter, often continuously repeated. The Johns Hopkins University Press.
