The bee subtribe Epanthidiina, a new taxon for the Neotropical clade of Anthidiini (Hymenoptera, Apidae, Megachilinae)

Anthidiini comprise a large, diversified, and widely distributed tribe of megachiline bees. Recently, morphological molecular analyses recovered five major monophyletic groups within the tribe. For this reason, we review current classification tribe, giving status subtribe to these lineages. A new subtribe, Epanthidiina (type genus: Epanthidium Moure), is proposed for large group restricted Neotropical region. Morphological phylogenetic hypotheses support taxonomic limits subtribe. We also propose genus, Urbanthidium species: Anthodioctes gracilis Urban), in order accommodate results from previous study which Holmberg came out paraphyletic. Two species are transferred gracile (Urban) comb. n., psaenythioides (Holmberg) n.
