Interpretive Summary: Bees of the wood nesting genus Chelostoma are found across much of the Northern Hemisphere. They have been divided into five subgenera that were thought to each contain related species. Recent DNA research on the family relationships among the species of Chelostoma discovered that one of these subgenera contained two separate groups of species, one in the western United States and the other from western Europe. A new name is therefore needed for the western United States species which is here given the subgeneric name Neochelostoma. A key to identify all of the subgenera is provided.

Technical Abstract: A new subgenus of Chelostoma Latreille is established for the New World group historically placed in Foveosmia Warncke. These species, placed herein in Neochelostoma Engel & Griswold, new subgenus, are differentiated from the Palearctic Foveosmia and a modified key is provided to the subgenera of Chelostoma.
