fibronectiini

Fibronectiini is a tribe name used in zoological taxonomy to organize a group of related genera within a subfamily of a larger family. In zoological nomenclature, a tribe ranks below a subfamily and above a genus. The exact composition and validity of Fibronectiini have varied in the literature, with some taxonomic treatments recognizing it as a distinct tribe while others subsume its member genera under different tribes or leave them unplaced.

The tribal assignment was historically based on shared morphological features observed in the included genera. Contemporary revisions may rely on molecular phylogenetics, and as such, the precise boundaries of Fibronectiini are not universally fixed across sources. This has led to instability in membership across taxonomic catalogs.

Concerning distribution and ecology: Given the variability in its circumscription, distribution data are inconsistent. Where Fibronectiini is recognized, member genera occur in diverse biogeographic regions, and the ecological roles reflect those of their broader subfamily.

Etymology and nomenclature: The name Fibronectiini is formed using the standard -ini suffix for tribes and typically derives from a designated or assumed type genus within the group. The spelling and rank conform to the International Code of Zoological Nomenclature, but the exact application depends on the taxonomic authority cited.
