Phylogeography and taxonomy of the blue-spotted maskray (ex-Neotrygon kuhlii; ikan pari totol biru) : the intricate story of a widespread species complex. Seminar, LIPI Research Center on Oceanography, Ancol on 19 October 2018

Abstract

The blue spotted maskray was once thought to be a single species widely distributed in the Indo-West Pacific, from the Red Sea to Fiji and from southern Japan to New South Wales. Genetics have shown that it actually consists of at least 12 distinct lineages with parapatric distribution. The available phylogenies suggest that the evolutionary origin of the species complex lies in the southwestern Pacific in the Miocene (between 5 and 23 million years ago). The blue-spotted maskray progressively colonized the Indo-West Pacific from the East to the West-The lineages in the western Coral Triangle and the Indian Ocean are the most recently evolved. The taxonomy of the blue-spotted maskray species complex is still an unfinished job, of which a detailed chronological account will be presented. Major but neglected contributions to the early stages of the taxonomic work on N. kuhlii were from French naturalist Jean-Rene Constant Quoy in 1828 and from Japanese artist Kawahara Keiga around 1830. Genetics led to a complete taxonomic reshuffle, starting with the pioneering DNA barcoding work of Australian geneticist Bob Ward in 2008, followed by acrimonious competition between traditional taxonomists and molecular geneticists. For nearly two centuries, the taxonomy of the species complex has been marked by neglect, confusion, and error.
