[Ichthyology • 2017] Neotrygon vali • A New Blue-spotted Maskray (Myliobatoidei: Dasyatidae) from the Solomon Archipelago Described from Its DNA Barcode

Neotrygon vali   Borsa, 2017


The blue-spotted maskray from Guadalcanal Island (Solomon archipelago) is morphologically distinct from Neotrygon kuhlii with which it was previously confused and it is genetically distinct from all other species in the genus Neotrygon. It is here described as a new species, Neotrygon vali sp. nov., on the basis of its nucleotide sequence at the cytochrome oxidase 1 (CO1) gene locus. It is unique in the genus Neotrygon by the possession of nucleotide T at nucleotide site 420 and G at nucleotide site 522 of the CO1 gene.

Keywords: new species, CO1 gene, molecular diagnosis, taxonomy
