The first fossil species of the caenohalictine bee genus Agapostemon Guérin-Méneville (Halictinae: Caenohalictini:Agapostemonina) is described and figured from a single male preserved in EarlyMiocene (Burdigalian) amber from the Dominican Republic. Agapostemon (Notagapostemon) luzziiEngel & Breitkreuz, new species, is compared with modern species and isnoteworthy for the absence of metafemoral modifications [in this regardplesiomorphically resembling the West Indian A. kohliellus (Vachal)and A. centratus (Vachal)], form of the head and protibial antennalcleaner, integumental sculpturing, and male terminalia, the latter of which arefortunately exposed and cleared. Briefcomments are made on the affinity of the species to others in the West Indies and surrounding regions as well as possible biogeographic implications.
