Uniramia

Definition

A taxonomic group that historically included the subphylum Hexapoda and the classes Myriapoda (centipedes and millipedes), characterized by having unbranched appendages. It is now considered a paraphyletic grouping and not widely used in modern taxonomy.

Etymology

From Latin 'uni-', meaning 'one', and 'ramus', meaning 'branch', referring to the unbranched appendages of organisms in this group.

Example

In historical classifications, insects, along with centipedes and millipedes, were classified under Uniramia due to their unbranched appendages.

Usage Notes
