Tribe (biology)
 | This article's lead section contains information that is not included elsewhere in the article. (May 2022) |
In biology, a tribe is a taxonomic rank above genus, but below family and subfamily.[1][2] It is sometimes subdivided into subtribes. By convention, all taxonomic ranks from genus upwards are capitalized, including both tribe and subtribe.
In
In botany, the standard ending for the name of a botanical tribe is "-eae". Examples include the tribes Acalypheae and Hyacintheae. The tribe Hyacintheae is divided into subtribes, including the subtribe Massoniinae. The standard ending for the name of a botanical subtribe is "-inae".
In bacteriology, the form of tribe names is as in botany, e.g., Pseudomonadeae, based on the genus name Pseudomonas.[3]
Rank recognition
An unfamiliar taxonomic rank cannot necessarily be identified as a tribe merely by the presence of one of the standard suffixes:[note 1]
- zoological -ini uniquely suffixes the animal tribe, [4]
- zoological -ina uniquely suffixes the animal subtribe[4]
- zoological -inae uniquely suffixes the animal subfamily[4]
- botanical -eae also suffixes class -phyceae, suborder -ineae, family -aceae, and subfamily -oideae (these additional -eae ranks are present in bacteria, plants, algae, and fungi, but not animals)[5][6]
Accordingly, working within animals alone, subfamily -inae, tribe -ini, and subtribe -ina are unique suffixes to their specific taxonomic ranks.[4] At the other extreme, working within algae alone, -eae suffixes class -phyceae, suborder -ineae, family -aceae, subfamily -oideae, and tribe -eae. The longer suffixes themselves suffixed with -eae must first be eliminated before recognizing an unfamiliar -eae designation as belonging to rank tribe.[5][6]
