One hundred and three extant plus eight fossil species in Dominican amber are treated: Tridactylidae (1), Tetrigidae (12), Eumastacidae (10 1 fossil), Acrididae (20), Pyrgomorphidae (2), Tettigoniidae (22), Gryllidae (30 7 fossils), Anostostomatidae (3), Gryllacrididae (1), and Gryllotalpidae (2). Two genera of Tettigoniidae are recorded for the first time from the island.
