Overview of our fauna (* –taxa not yet in the guide)
Jugal lobe in HW longer than submedian cell. Basal vein straight or nearly so. One subantennal suture below each antennal socket. Glossa (tongue) short, bilobed or truncate.
2nd and 3rd submarginal cells are roughly the same size in Colletidae, while 2nd one is distinctly smaller in Andrenidae.(2)(3)
Guide to eastern genera in(4)
Worldwide, most species live in South America and Australia.
Two subfamilies, Euryglossinae and Hylaeinae, lack external pollen-carrying apparatus (scopa), they carry pollen in their crops.
