This paper deals with the taxonomic composition, distribution and bionomics of the genus Copelatus Erichson, 1832 in Cuba. Two new species, C. cordovai sp. nov. and C. danyi sp. nov., are described. Diagnostic characters including illustrations of male genitalia are provided and illustrated for C. barbouri Young, 1942, C. caelatipennis angustatus Chevrolat, 1863, C. caelatipennis princeps Young, 1963, C. cubaensis Schaeffer, 1908, C. darlingtoni Young, 1942, C. insolitus Chevrolat, 1863, C. montivagus Young, 1942, and C. posticatus (Fabricius, 1801). A key for the 10 species of Copelatus occurring in Cuba is provided. Copelatus blatchleyi Young, 1953, not recorded from Cuba, is included in the key due to its presence in extreme southern Florida and the Bahamas. Maps of known distribution of Cuban Copelatus are given for each species. Copelatus caelatipennis princeps is recorded for the first time from the West Indies. Records of C. glyphicus (Say, 1823) and C. anastomosans Guignot, 1952 from Cuba are probably misidentifications and the species are not considered to be members of the Cuban fauna.
