The first fossil exomalopsine bee is described and figured from two females, one very partially preserved in Early Miocene amber from the Dominican Republic. Anthophorula (Anthophorula) persephone Engel, new species, is distinguished from its modern counterparts mainly by the broader pterostigma in which its inner breadth is greater than that of its marginal veins. This record expands the Dominican amber melittofauna to 21 species. Brief comments are made on the discovery as well as the Dominican amber bees in general. The new combination Thaumatosoma (Chalicodomopsis) glaesaria (Engel) is established.
