Order Hymenoptera (Ants, Bees, Wasps and Sawflies)
No Taxon (Aculeata - Ants, Bees and Stinging Wasps)
No Taxon (Apoidea (clade Anthophila) - Bees)
Family Halictidae (Sweat, Furrow, Nomiine, and Short-faced Bees)
Subfamily Halictinae (Sweat and Furrow Bees)
Tribe Halictini
Genus Halictus (Furrow Bees)
No Taxon (Subgenus Halictus sensu lato)
No Taxon ligatus or poeyi, subgenus Odontalictus
Identification
Packer, L. (1998) determined these to be two separate species (Previously only H. ligatus was considered valid). They are best separated based on range OR DNA sequence data in areas of sympatry.
Remarks
Known to be a species complex, likely to be split further in the future. The most distinctive "cryptic" forms are Mexican.
