GENUS EUCERA

Author: Scopoli 1770

Type species: Apis longicornis Linnaeus, 1758, by designation of Latreille, 1810: 439.
Subgenera: Eucera s.str.; Synhalonia; Tetralonia.
Synonyms: Macrocera Latreille 1810 (not Meigen 1803); Xenoglossodes; Melissina.
Clade: Anthophila
Family: Apidae
Subfamily: Eucerinae
Tribe: Eucerini
Estimated min and max body length from the genus.
Map source: S. Reverte 2023, ORBIT.
Estimated difficulty to accurately identify a specimen as belonging to this genus.
Distinctive traits
  • Males with very long antennae
  • Females with basitibial plate
  • Elevated clypeus
  • Long mouthparts
  • Submarginal cells of different sizes when 3 submarginal cells
Pictures of distinctive traits
Morphologically close genera and how to distinguish them:
  • Eucera - Tetralonia 
Eucera species have two or three submarginal cells, a protuberant clypeus, a linear malar space and normally unbranched scopal hairs
Tetralonia species have three submarginal cells, a flat clypeus, a non-linear malar space and normally plumose scopal hairs. 
  • Eucera - Anthophora, Amegilla & Habropoda
Eucera species have different-size submarginal cells
Anthophora, Amegilla & Habropoda species have submarginal cells of equivalent sizes







General comments on Eucera species identification
Since Dorchin (2018), Eucera now comprises every species of Eucerini in Europe, and is subdivided in three subgenera: Eucera s.str (2 submarginal cells), Synhalonia and Tetralonia.
Currently, Eucera species are amongst the most difficult bees to identify in Europe. In absence of a revision of the european species, we lack proper criteria for species identification, and putting a species name on specimens without having proper reference specimens compared to type specimens is hazardous. Unless you are in areas with very few species, an expert's eye will be required to sort out the specimens.
SPECIES IDENTIFICATION TOOL
Sorry, but the species identification tool is not yet available for Eucera.
