Brief Summary
provided by Catalog of Hymenoptera in America North of Mexico
Members of the Halictini are found on all continents and many of the islands. In the Western Hemisphere they are present from Alaska and northern Canada south to southern Argentina (Province of Chubut) and occupy most continental islands and many of the islands in the West Indies, as well as, Bermuda and Fernando de Noronha. As now understood, the tribe is represented in the Western Hemisphere by 19 genera, only five of which also occur in the Old World (Dialictus, Halictus, Lasioglossum, Evylaeus, and Sphecodes). Of the 14 genera found only in the Americas, four are known only from North America (Hemihalictus, Mexalictus, Paralictus, and Sphecodogastra), three only from South America (Pseudagapostemon, Ruizantheda, and Zikaniella), three occupy both North and South America, as well as, the West Indies (Agapostemon, Microsphecodes, and Habralictus, and four, while present in both North and South America, have not been taken in the West Indies (Caenohalictus, Paragapostemon, Ptilocleptis, and Rhinetula). In all more than 700 species including those considered as unplaced taxa of the Halictini are currently recognized from the Americas.
