Thirteen new fossil eucnemid taxa (Coleoptera: Elateroidea) are described from amber deposits excavated from the vicinity of Santiago, Dominican Republic. Two new genera, Mioxylobius and Paleo­quirsfeldia are described. The following 13 new species are described from Dominican amber: Mioxylobius bicolor, Balistica serrulata, Paleoquirsfeldia epicrana, Dyscharachthis dominicana, Idiotarsus poinari, Eurypty­chus antilliensis, Euryptychus hispaniolus, Plesiofornax caribica, Fornax dominicensis, Fornax serropalpoides, Dromaeolus argenteus, Nematodes miocenensis and Nematodes thoracicus. Each new species are both diag­nosed and illustrated. Calyptocerus Guérin-Méneville and Lissantauga Poinar are shown to be congeneic, resulting in a new combination: Calyptocerus epicranis (Poinar, 2013). Summaries of fossil eucnemid dis­coveries, highlighting differing hypothesis of prehistoric Caribbean island formations/speciation, accounts of ancient Dominican Republic environmental conditions and Dominican Republic amber are provided.
