Neolarrini
Neolarrini is a tribe of cleptoparasitic cuckoo bees in the subfamily Nomadinae, family Apidae. Following recent phylogenomic revision, this tribe now encompasses approximately 40 species across five genera: Biastes, Neolarra, Rhopalolemma, Schwarzia, and Townsendiella. The tribe was expanded to include the former tribes Biastini and Townsendiellini as synonyms to ensure monophyly. Neolarrini likely originated in the Nearctic during the mid-Eocene and is exclusively composed of parasites of oligolectic host bees.
