This is the first description of a zygopteran from Dominican Amber and of a coenagrionid from any amber source. Holotype 9; Dominican Republic, Cordillera Septentrional, “La Toca” mine; age Upper Eocene/Lower Oligocene; deposited in private coll, of J. Work (Ashland, OR, USA). On the basis of the elongate thin abdomen, as well as the known habits of the 2 extant congeners, it can be surmised that the larvae lived in tank bromeliads. The find provides supporting evidence that the genus Diceratobasis is endemic to the Greater Antilles.
