Latreille 1802


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,[1] and some extinct genera such as Calyptapis and Oligobombus.[2]


Bombus cerdanyensis was described from Late Miocene lacustrine beds of La Cerdanya, Spain in 2014.[3]

Calyptapis florissantensis was described by Cockerell in 1906 from the Chadronian (Eocene) lacustrine – large shale of Florissant in the USA.[4][5]

Oligobombus cuspidatus was described by Antropov in 2014 from the Insect Bed of the Bembridge Marls in the Eocene of the Isle of Wight, England. The fossil was described by re-examining a specimen in the Smith Collection.[6][7]
