Tarbagan marmot Marmota sibirica, photographed by Eva Součková.

Belongs within: Xerinae.
Contains: Tamias, Spermophilus.

The Marmotini are a clade of either terrestrial or terrestrially nesting squirrels, including the chipmunks, marmots and prairie dogs. Many Marmotini nest socially, and all undergo at least some period of hibernation over winter. The most sociable are the prairie dogs of the North American genus Cynomys, which form large 'towns' containing numerous family groups.

Characters (from Moore 1959): Two transbullar septa per auditory bulla; orbital length at least 1.15× interorbital breadth; no temporal foramen in squamosoparietal suture; sphenopalatine foramen usually with less than half area of sphenoidal fissure; supraorbital notches generally open and trenchant.
