Eucerini
tribe of bees
The Eucerini (often called longhorn bees or long-horned bees) are the most diverse tribe in the family Apidae, with over 32 genera worldwide that were previously classified as members of the family Anthophoridae. All species are solitary, though many nest in large aggregations, and large "sleeping" aggregations of males are found occasionally. Most genera are distinctive in the unusually long male antennae from which the tribe derives its name (eucer- means true horned). They are most diverse in the Western Hemisphere.
Classification
The classification within the tribe is rather chaotic, as many of the genera are small and poorly characterized, with the bulk of species (about 500) in only five genera. This is a group in serious need of a thorough taxonomic overhaul, and the fusion of many genera would likely result (a revision in 2000 eliminated seven genera and another in 2018 eliminated six more).

The public source identifies “Eucerini” as tribe of bees. This brief keeps that definition visible, then builds a research path around Eucerini, tribe and bees.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Eucerini”, the useful work is to connect “tribe of bees” to the records capable of establishing context and consequence.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated May 22, 2026. The linked authority identifier is Q3059472. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2000, 2018, 1957 and 1909.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
