In biology, a tribe is a taxonomic rank above genus, but below family and subfamily.
By convention, all taxa ranked above species are capitalized, including both tribe and subtribe.
Examples include the tribes Caprini (goat-antelopes), Hominini (hominins), Bombini (bumblebees), and Thunnini (tunas).
[3] An unfamiliar taxonomic rank cannot necessarily be identified as a tribe merely by the presence of one of the standard suffixes:[note 1] 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.
