Four new stygobitic cirolanids (Crustacea: Isopoda) from the Caribbean: with remarks on intergeneric limits in some cirolanids

Four new stygobitic and troglomorphic cirolanids are described from various parts of the Caribbean. Cirolana (C.) troglexuma n. sp. is described from a cave on one of the Exuma Cays, Bahamas; two subgenera are recognized in g.Cirolana: sg. Cirolana including troglexuma as only presently know stygobitic species, and sg. Anopsilana equally well represented by subterranean and by epigean species. Haptolana bowmani n. sp. and H. belizana n. sp. inhabit caves of Yucatan and Belize, respectively; interestingly they are both abundantly different from the Cuban species of this stygobenthic genus, showing more similarity with the species from Somalia and W. Australia. Jamaicalana pleoscissa n.g. n. sp. was discovered in a cave from Jamaica; the new genus has affinities with Anopsilana and Bahalana, but a combination of characters -some of them highly original- renders definition of a new genus necessary. Bahalana mayana Bowman should be removed from that genus, whereas Dodecalana yagerae Carpenter is an interesting species of Bahalana
