Abstract: The present study investigates the freshwater prawn diversity of some water bodies from Jammu region of Jammu and Kashmir State of India. Jammu is located on the Southern slopes of Shivalik hills of Himalayas at an altitude of 366 metres above the sea level. In the water bodies of Jammu region, the genus Macrobrachium earlier was represented by two species viz. M. dayanum and M. kistnense. In the present study, a total of 4 freshwater prawn species have been reported from the surveyed areas. These are Macrobrachium dayanum, M. kistnense, M. lamarrei lamarrei and M. siwalikense. M. dayanum and M. kistnense are previously on record whereas M. lamarrei lamarrei and M. siwalikense have been reported for the first time in this region. In the present text the newly reported species viz. M. lamarrei lamarrei and M. siwalikense have been taxonomically described and their key identification features have been briefly discussed.
