Neotrygon indica Pavan-Kumar, Kumar & Borsa, 2017


Abstract 
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. Here the Indian-Ocean maskray is described as a new speciesNeotrygon indica sp. nov. A diagnosis based on its distinct colour patterns and nucleotide sequence at the CO1 locus is proposed.

 Keywords: Taxonomy; Diagnosis; Distribution
