The 20 species of Neogene Scleractinia in the suborders Caryophylliina and Dendrophylliina known from the Dominican Republic are revised and illustrated. This research was based on 1590 specimens obtained primarily from the collections of the Naturhistorisches Museum, Basel, Switzerland; National Museum of Natural History, Smithsonian Institution, Washington, DC, U.S.A.; and Tulane University, New Orleans, LA, U.S.A. Eight new records are reported for the Neogene of the Dominican Republic, including four new species: Antillocyathus alatus, Trochocyathus chevalieri, T. duncani, and Paracyathus sinuosus. Special attention is given to the genus Asterosmilia, since half (five) of the known species in this genus occur in the Dominican Republic. Most species described herein are assumed to constitute a deep-water fauna by analogy to depth ranges of the same or similar species known from the Recent. Certain localities and parts of formations are inferred to represent deep-water (> 200 m) facies. These inferences may aid in the paleoecological interpretation of other fossils collected from these areas.
