Morphology
The phrase is transparently composed: 'subfamily' denotes a taxonomic rank below family, and 'Petauristidae' names the family of gliding mammals. A learner who knows both terms can readily infer this refers to a subordinate group within the Petauristidae (i.e., a group of flying squirrels), so the meaning is directly derivable from the constituents.
Etymology
Subfamily Petauristidae may come from Greek words meaning 'jump' or 'glide', which gives the picture of a small squirrel stretching a skin 'wing' to glide from tree to tree. That's why the name fits this group of Old World flying squirrels.
