Phylogenetic and biogeographic analyses by Vergara (1980, 1981) did not support this subdivision of the genus, and in Nielsen et al. (1999) and Nielsen (2002) it was abandoned without arguments.

The Bahamas consist of two major banks: The Great Bahama Bank is a large, shallow water carbonate platform that also includes the major islands of New Providence, Bimini, Andros, Cat, Eleuthera, Great Exuma and Long Island. The Great Bahama Bank is separated from the Little Bahama Bank (containing the major Islands Grand Bahama and Abaco) by the Northeast (3800 to 4700 m deep) and Northwest (700 to 2800 m deep) Providence Channels. The banks are made up of limestone of shallow water origin having been deposited to a depth of at least 4500 m since the Cretaceous. Numerous caves and

karst features are present on most islands. In the Bahamas, such partially or totally submerged cave systems, occurring both inland and on the seabed, are referred to as “blue holes”. On Long Island for example, more than 60 blue holes are listed on topographic maps. Most notable of these is Dean's Blue Hole -the World's deepest marine cave reaching depths of 200 m (Wilson 1994).

Despite the new records and collections, morphological data have only been published from the two type specimens and thus no information on the variability and ontogeny of the species is available. During examination of 50 specimens (42-166 mm SL) collected at seven different islands, it became obvious that at least two species are represented in the Bahamas. One new species is here described and
