tribe (biology)
According to Wikipedia:
In biology, a tribe is a taxonomic rank above genus, but below family and subfamily.
I don’t think I had ever encountered that meaning of the word tribe before.
That Wikipedia article also says that in zoology, tribe names tend to end in -ini and subtribe names tend to end in -ina, while in botany and bacteriology, tribe names end in -eae and subtribe names end in -inae.
