underfamilier

An underfamily is a taxonomic rank used in biological classification, specifically within the context of the animal kingdom. It is a subdivision of a family, and is itself subdivided into genera. The term "underfamily" is often used to group together closely related families that share certain characteristics but are not closely enough related to be considered a single family.

The use of underfamilies is particularly common in the classification of insects, where they are used to group together families that share similar morphological or behavioral characteristics. For example, the family Formicidae, which includes ants, is divided into several underfamilies based on characteristics such as the structure of the mandibles and the presence or absence of a sting.

The rank of underfamily is not universally recognized, and some taxonomists may choose to use other ranks, such as tribe or subfamily, to group together closely related families. However, the use of underfamilies can be a useful tool for organizing and understanding the diversity of life on Earth.
