| Summary: | The taxonomic identification of mantis shrimp Lysiosquilla maculata was performed through DNA barcoding analysis of specimens collected from the Kasimedu fishing port, Chennai coast, Tamil Nadu, India. The mitochondrial cytochrome oxidase subunit I (mtCOI) gene with a region of 650 bp was sequenced for phylogenetic analysis. In the present record, mitochondrial gene sequences were used to identify the mantis shrimp. This is the first confirmed DNA barcoding record from Indian waters, whose mtCOI sequence was deposited in GenBank. The Neighbor-joining method was used for phylogenetic analysis. The calculated pairwise genetic distance with five closely related species ranged from 0.01 to 0.094%. The morphological and molecular analysis confirm that the specimens collected correspond to L. maculata.
