Abstract: 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.
