Euphractinae is an armadillo subfamily in the family Chlamyphoridae.

Euphractinae are known for having a well developed osteoderm that has large cavities filled with adipose tissue, and more hair follicles with well developed sebaceous glands in comparison to the Dasypodidae sub family. These are believed to be evolutionary adaptations in the Euphractinae to support it in the cooler climate that it usually lives in.[1]
