“…Approximately 340 species have been recognized and grouped into 17 species groups (Lynch, 1976). Evolutionary relationships in the genus are complex because of the overwhelming number of species, the intraspecific variation evident in many species (Cochran and Goin, 1970;Goin, 1947Goin, , 1954Lynch, 1967;Lynch and Duellman, 1980;Rivero, 1978;Schwartz, 1973Schwartz, , 1974Schwartz, , 1976, and the lack of taxonomic characteristics that can be applied to all the species over their entire ranges. The characters used to define species groups in the West Indies are not useful to define groups in South and Central America (Lynch, 1976).…”

Chromosomes from 20 species oi Eleutherodactylus from Puerto Rico and Cuba as well as chromosomes oi Sminthillus limbatus from Cuba were analysed and compared. Puerto Rican Eleutherodactylus have 26or 30-chromosome karyotypes which may reflect two separate ancestral invasions. Cuban Eleutherodactylus species have 18-, 28-, 30-, and 32-chromosome karyotypes which may be related to three chromosomal groupings and possibly three separate invasions into Cuba. Sminthillus limbatus is karyotypically similar to ricordi group members oi Eleutherodactylus in Cuba and, chromosomally, there is little justification for its generic distinction. Some of the chromosomal groupings correspond to morphologically determined species groups and have affinities with mainland species of Eleutherodactylus or Syrrhophus. The apparently rapid chromosomal evolution in Eleutherodactylus is unusual in the Anura and should be useful for examining general mechanisms of chromosomal evolution as well as the ecological and genetic significance of chromosomal variation. Preliminary results are presented for C-banded Eleutherodactylus chromosomes which reveal densely staining telomeres and interstitial constitutive heterochromatin.
