A new distribution record of stomatopods Odontodactylus japonicus (De Haan, 1844) and Lysiosquilla tredecimdentata (Holthuis, 1941) from the Puducherry coastal waters, east coast of India

Abstract

Stomatopods in India are well known with 79 species recorded to date. Here I report the Odontodactylus japonicus (De Haan, 1844) and Golden Mantis Shrimp Lysiosquilla tredecimdentata Holothuis, 1941 for the first time in Puducherry coastal waters. A single specimen of Lysiosquilla tredecimdentata was collected from by-catch in the Nallavadu landing centre, Puducherry coast on 19 November 2019 and two specimens of L. tredecimdentata were recorded again in Pillaichavadi landing centre of Puducherry coast on 22 November 2019. One specimen of Odontodactylus japonicus was collected at Nallavadu landing centre, Puducherry coast on 20 December 2019. The present study was undertaken to identify the status of distribution, habitat, and ecological aspects along with the information of spread, confinement, endemism as well as rare, threatened and endangered species. The significance of these new observations is to discern the taxonomic position and characteristics for better understanding of the mantis shrimp group. The specimens were identified, described, illustrated, and measured morphometrically.\xa0
