Nine of these species (N. australiae, N. bobwardi, N. caeruleopunctata, N. malaccensis, N. moluccensis, N. orientale, N. vali, N. varidens, N. westpapuensis) have already been formally described and two (Indian Ocean maskray and Ryukyu maskray) remain undescribed. Here, the Indian Ocean maskray is described as a new species, Neotrygon indica sp. nov. Specimens of the new species were generally characterized on their dorsal side by a moderately large number of small ocellated blue spots, a low number of medium-sized ocellated blue spots, the absence of large ocellated blue spots, a high number of dark speckles, a few dark spots, and a conspicuous occipital mark. The new species formed a distinct haplogroup in the tree built from concatenated nucleotide sequences at the CO1 and cytochrome b loci. A diagnosis based on colour patterns and nucleotide sequences at the CO1 and cytochrome b loci is proposed. The distribution of N. indica sp. nov. includes the Indian coast of the Bay of Bengal, the Indian coast of the Laccadives Sea, and Tanzania. Considerable sampling effort remains necessary for an in-depth investigation of the phylogeographic structure of the Indian Ocean maskray. specialized New species Mitochondrial DNA Diagnosis Distribution OCEAN INDIEN 034 341 2 120-130 2018 1631-0691 https://www.documentation.ird.fr/hor/fdi:010072461 10.1016/j.crvi.2017.2018.01.004 1631-0691 [F B010072461] https://www.documentation.ird.fr/hor/fdi:010072461 https://www.documentation.ird.fr/intranet/publi/2018/04/010072461.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2018-05-04 2018-05-04 fdi:010072461 fre
