Seventy one species have been recorded which diversity patterns are analyzed, including particular data front the eastern and western regions as the Canarian Archipelago and Cabo Verde Islands, and the Yucatan Channel (between Gulf of Mexico and Caribbean Sea). respectively. Zoogeographic affinities and faunistic composition differences are discussed.
