Abstract

Deep-sea lobster Polycheles typhlops Heller, 1862 and two squat lobsters Munidopsis scobina Alcock, 1894 and Paramunida bineeshi Macpherson, Chan, Kumar and Rodriguez-Flores, 2020 belonging to the family Polychelidae, Munidopsidae and Munididae respectively forms the new records from the Arabian sea along the southwest coast of India. Samples were obtained from the commercial bottom trawlers at a depth of 200–300 m operated off Sakthikulangara fishing harbour (8°56’60.78” N / 76°32’34.27” E) from the Arabian Sea, Kerala, India, from January to December 2020. DNA barcoding and phylogenetic analysis with mitochondrial gene sequencing were used to explore the genetic distances within the genera Polycheles, Munidopsis and Paramunida revealing high interspecies genetic divergence.
