New records of coastal fishes in the northern Rio de Janeiro State, Brazil, with comments on the biogeography of the south-western Atlantic Ocean.

abstract：:A novel Caribbean species Albula sp. cf. vulpes in the family Albulidae (bonefishes) was diagnosed through genetic and morphometric study. Phylogenies derived from 16S rRNA sequences revealed deeply separated lineages among Caribbean bonefishes. Mitochondrial DNA sequence divergences indicated a separation between 3.0...
