Interpretive Summary: The identities of mason bees (genus Osmia) are not well known with new species often found. This is true for the small group of species in the subgenus Diceratosmia that is found in the southern United States, the Caribbean, Mexico, and Central America. Four of the eleven species are new to science. A key to identify these species is given along with all that is currently known about the biology, plants visited, and known distribution.

Technical Abstract: We revise the eleven species of the North American subgenus Osmia (Diceratomsia), and newly describe four species: Osmia (Diceratosmia) exquisita, n. sp., from Honduras; Osmia (Diceratomia) gonzalezi, n. sp.; and Osmia (Diceratomia) spinulifera, n. sp., from Mexico; and Osmia (Diceratomsia) lacunosa, n. sp., from the Bahamas. We provide diagnoses for the remaining seven species and a key to the known males and females of all species. In addition, we review the known nesting biology, floral hosts, and geographic range of the species.
