Definition

1. Proper noun:
   • A taxonomic family of marsupials: "Family Phalangeridae" is the scientific name for a family of arboreal marsupials commonly known as phalangers or possums, which includes the cuscuses and brushtail possums. It is distinct from the family that includes koalas.

Usage Notes

• The term "Family Phalangeridae" is used in formal, scientific contexts such as zoology, biology, and taxonomy. It refers specifically to the taxonomic grouping. In non-scientific contexts, the common names of its members (e.g., possum, cuscus) are used instead.
• It is a singular, collective noun referring to the entire family group.

Examples

• Proper noun:
  • The researcher is studying the evolutionary history of Family Phalangeridae.
  • Family Phalangeridae is primarily distributed in Australia, New Guinea, and surrounding islands.

Advanced Usage

• In taxonomic hierarchy: The term is used to specify a rank above genus and below order. For example: Order Diprotodontia > Suborder Phalangeriformes > Family Phalangeridae.
  • The species was reclassified and moved to Family Phalangeridae.

Synonyms

Important Clarification

• Koalas are not in Family Phalangeridae: Based on the reference context provided, it is critical to note that koalas (family Phascolarctidae) are a separate taxonomic family. The reference context listing "koalas" appears to be an error or a misgrouping for a different purpose. "Family Phalangeridae" properly includes phalangers/possums, not koalas.
  • Correct: Phalangers belong to Family Phalangeridae.
  • Incorrect (based on modern taxonomy): Koalas belong to Family Phalangeridae. (Koalas belong to Family Phascolarctidae).
