Abstract
Knobtooth Prawn, Macrobrachium mammillodactylus (Thallwitz, 1891), is an amphidromous freshwater prawn that occurs in the tropics of the western Pacific Ocean. Here, we report a new record of this species from Miyako Island, in the Ryukyu Archipelago, Japan. The obtained specimens were mature, suggesting that they had overwintered. This record updates the northern limit of M. mammillodactylus and suggests an expansion of the range of this species.
