subtribal

Subtribal refers to a taxonomic rank used in biological classification, positioned below the rank of tribe and above the rank of genus. This hierarchical system is employed by biologists to categorize and organize living organisms. The subtribe serves as an intermediate level to group genera that share a particularly close common ancestry and exhibit more specific similarities than those shared by all members of the parent tribe.

The establishment of subtribes is not as universally applied as higher ranks like family or order, and their use can vary among different taxonomic groups and among individual researchers. Their recognition is often based on detailed morphological, genetic, or other biological data that reveal distinct lineages within a tribe. For example, a tribe might contain several genera with noticeable differences, leading taxonomists to create subtribes to better reflect these evolutionary relationships.

The classification system in biology is dynamic, and the boundaries and definitions of taxonomic ranks, including subtribes, can be revised as new scientific discoveries are made. The purpose of using ranks like subtribal is to create a structured and organized understanding of biodiversity, facilitating scientific communication, research, and the study of evolutionary history.
