Molecular phylogeny and phylogeography of the Cuban cave-fishes of the genus Lucifuga: Evidence for cryptic allopatric diversity

► mtDNA phylogeny of the Cuban cave fishes (Lucifuga) revealed three main clades. ► Nuclear and morphological characters support these clades. ► Five putative new cryptic species were identified within two of these clades. ► Phylogeography indicates that dispersal and vicariance have moulds this diversity. ► The evolutionary trends of four phenotypic traits were inferred.
