The blue-spotted maskray, previously N. kuhlii, consists of up to eleven lineages representing
separate species. 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.
