Abstract
The identity of Ariosoma dolichopterum in Indian waters has revised. Ariosoma dolichopterum from India is an undescribed species and described herein as Ariosoma tamilicum sp. nov. based on morphology and molecular studies. Ariosoma tamilicum is morphologically closely related to Ariosoma emmae from the Taiwan waters but exhibits 13.4% genetic divergence in mitochondrial CO1 gene sequences. The formal description for the new species is provided and discussed.
