Taxonomic Revision and List of Cyanobacteria from the Greater Antilles (Cuba, Haiti, Hispaniola, Jamaica, and Puerto Rico). Pt 1

The purpose of this study is to document the cyanobacteria from Greater Antilles and to revise and update nomenclature to reflect current taxonomic understanding for previously documents species from Nostocale and Chroococcales. There are a total of species 328 species and infraspecies were identified. Puerto Rico had the most at 209 species identified from the Greater Antilles, while Cuba had 106 species, Jamaica had 54, Haiti had 5, Hispanolia had 3 and 19 species were identied from the Caribbean Sea. No species have been identified from the Dominican Republic and Cayman Islands. The dominant order was Nostocales with 205 species (55 Aphanizomenonaceae, 46 Scytonemataceae, 37 Rivulariaceae, 21 Stigonemataceae, 15 Nostocaceae, 15 ,Tolypothrichaceae, 8 Hapalosiphonaceae, 5 Leptobasaceae and 3 Nodulariaceae). Chroococcales was the second most abundant order with 123 species (77 Microcystaceae, 30 Chroococcaceae, 9 Pleurocapsaceae, Gomphosphaeriaceae and Cyanothrichaceae both with 3 and Entophysalidaceae only had one species).
