This occurrence dataset encompasses the specimens identified and reviewed by Rightmyer and Griswold in their work, "A revision of the subgenus Osmia (Diceratosmia), with descriptions of four new species (Hymenoptera, Megachilidae)" (2017).
This data publication aims to serve as a reliable resource with definitive species identifications that includes more recent material reviewed subsequently by the original authors. The dataset seeks to address the challenges highlighted by Meier et al. (2004) for reliable datasets: (1) misidentification of unrevised museum specimens; (2) the broad range of private and public collections included in specimen lists from revisionary studies; and (3) the cost-effectiveness of obtaining specimen records from revisions. The eleven species of the North American subgenus Osmia (Diceratosmia) are revised, four of which are new: Osmia (Diceratosmia) exquisita, n. sp., from Honduras; Osmia (Diceratosmia) gonzalezi, n. sp., and Osmia (Diceratomia) spinulifera, n. sp., from Mexico; and Osmia (Diceratosmia) lacunosa, n. sp., from the Bahamas. Diagnoses for the remaining seven species and a key to the males and females of all species are provided. Additional taxonomic changes include Osmia botitena Cockerell reduced junior synonym of Osmia subfasciata Cresson, and Osmia marilaunidii Cockerell removed from synonymy and recognized as valid species. In addition, the known nesting biology, floral hosts, and geographic range of each species is summarized.

We thank Connal Eardley and an anonymous reviewer for their helpful comments and suggestions. We also wish to acknowledge our debt to the first reviser of Diceratosmia, Charles Michener, who was a wonderful mentor to both of us.
