Bombini
Tribe of bees
The Bombini are a tribe of large bristly apid bees which feed on pollen or nectar. Many species are social, forming nests of up to a few hundred individuals; other species, formerly classified as Psithyrus cuckoo bees, are brood parasites of nest-making species. The tribe contains a single living genus, Bombus, the bumblebees, and some extinct genera such as Calyptapis and Oligobombus. The tribe was described by Pierre André Latreille in 1802.

Bombus cerdanyensis was described from Late Miocene lacustrine beds of La Cerdanya, Spain in 2014.
Calyptapis florissantensis was described by Theodore Dru Alison Cockerell in 1906 from the Chadronian (Eocene) lacustrine, large shale of Florissant in the US.
